Figure 2. Main Elements of the UPS System

If utility power is interrupted or falls outside the parameters specified in Chapter 10, “Product Specifications,” the UPS uses a backup battery supply to maintain power to the critical load for a specified period of time or until the utility power returns. For extended power outages, the backup battery supply allows you to either transfer to an alternative power system (such as a generator) or shut down your critical load in an orderly manner.

The operation of the UPS system is described in greater detail in Chapter 3, “Understanding UPS Operation.” Chapter 10, “Product Specifications,” outlines the storage and operating specifications for the UPS and optional battery.

164201036 Rev. D 041500

Understanding UPS Operation

Your UPS functions automatically to supply AC electrical power to your

critical load. The UPS always operates in one of three modes:

· In Normal mode, the critical load is supplied by the inverter, which derives its

power from rectified utility AC power. In this mode, the rectifier also provides charging current for the battery.

· In Battery mode, the battery cabinet provides DC power, which maintains

inverter operation. The battery supports the critical load.

· In Bypass mode, the critical load is directly supported by utility power.

The UPS continually monitors itself and the incoming utility power, and automatically switches between these modes as required, with no operator intervention. The sophisticated detection and switching logic inside the UPS ensures that operating mode changes are automatic and transparent to the critical load. The UPS switches operating modes in response to these system events:

· A command is an intervention that is externally initiated by an operator or by

some site action. A command causes the UPS to switch operating modes; it usually does not require any further action by you.

· A notice is a minor system event that may or may not require your attention.

· An alarm is a system event that requires immediate operator intervention.

System events, alarm horns, and indicator lights are described in Chapter 11, “Responding to System Events.”

Powerware 9315 (200 kVA ---300 kVA) Operation

164201036 Rev. D 041500

Normal Mode

In Normal mode, utility AC power is supplied to the rectifier. The rectifier supplies DC power to the inverter, which then supplies the critical load with AC power. The rectifier also provides charging power to the battery. The battery charge condition is monitored by the UPS and reported by a status indicator on the Monitor Panel. The message “System Normal” appears in the status area of the LCD screen.

Figure 3 shows the path of electrical power through the UPS system when the UPS is operating in Normal mode.

(closed)

If the utility AC power is interrupted or is out of specification, the UPS automatically switches to Battery mode to support the critical load with no interruption. When utility power returns, the UPS returns to Normal mode.

If the UPS system becomes overloaded, the UPS switches to Bypass mode. The UPS automatically returns to Normal mode when the error condition is cleared and system operation is restored within specified limits.

Output

If the UPS suffers an internal failure, it switches automatically to Bypass mode and remains in that mode until the failure is corrected and the UPS is back in service.

164201036 Rev. D 041500

Bypass Mode

The UPS automatically switches to Bypass mode if it detects an overload, load fault, or internal failure. The bypass source supplies the commercial AC power to the load directly.

CAUTION: The critical load is not protected while the UPS is in Bypass mode.

You can transfer the UPS from Normal mode to Bypass mode manually. However, the UPS switches automatically to Bypass mode whenever the inverter can no longer supply the critical load. If the UPS transfers to Bypass mode from Normal mode due to any reason other than operator intervention, the UPS automatically attempts to transfer back to Normal mode (up to three times within a 10-minute period). The fourth transfer will lock the critical load on the bypass source and requires operator intervention to transfer.

Bypass mode is a normal operating mode, and not an alarm condition. However, if the UPS is unable to return to Normal mode following an automatic transfer to Bypass mode, an alarm condition will be recorded.

164201036 Rev. D 041500

BATTERY

Battery Mode

The UPS transfers to Battery mode automatically if a utility power outage o ccurs, or if the utility power does not conform to specified parameters. In Battery mode, the battery provides emergency DC power that the inverter converts to AC power. When the UPS switches to Battery mode, the alarm indications depend on the cause and condition of the battery charge. The length of time the system can operate in Battery mode depends on loading and the battery supply capacity.

When the discharging battery voltage reaches the lower limit of UPS operation capability, the critical load transfers to Bypass mode if it is available. If Bypass input is not available, a “Shutdown Imminent” warning occurs. The warning time before critical load loss occurs is approximately 2 minutes, depending on battery capacity and the amount of loading.

If incoming power returns to within specified parameters, the UPS automatically returns to Normal mode and alarm indicationsclear. However, the process of returning to Normal mode is not instantaneous. The rectifier gradually draws increasing power from the incoming utility until Normal mode is achieved.

The following describes the switches on the Control Panel (see Figure 7):

· The MODE switch is a two-position rotary switch that controls the manual

transfer of the UPS to and from Bypass mode. The MODE switch is used to:

--- Place the critical load in Bypass mode when the UPS is operating in Normal mode and the bypass source is w ithin acceptable limits. If the transfer does not occur within 2 seconds, an alarm sounds.

--- Prevent transfer to Normal mode when the UPS is in Bypass mode.

--- S hu t d ow n t h e power processing unit (inverter and rectifier) of the UPS.

· The BATTERY switch is a two-position rotary switch that allows you to manually

shunt trip the battery breakers in remote cabinets.

· The circuit breaker (CB1) switch controls the operation of the rectifier and

inverter. If CB1 is on (closed), the rectifier turns on when the START switch is activated and the proper voltage is at the input terminals.

· The PUSH TO RESET pushbutton is described in the “Resetting the UPS

System after Load Off” section of Chapter 12.

· The START switch activates the power controls on the Control Panel. The

START switch is center-biased (the key will rest only in the upright position). Its

operation is similar to that of an automobile ignition switch. After setting the operator controls, you turn the START switch to the right momentarily to activate the controls. When you release it, it returns to the upright position.

The following sections describe how to operate these controls to start, stop, or change the operating mode of the UPS.

To Place the UPS in Normal Mode:

1. Close Input Power Feeder breaker

2. Be sure the Load Off PUSH TO RESET pushbutton is pressed in.

3. Turn t he BATTERY switch to NORMAL.

4. Turn t he MODE switch to NORMAL.

5. Move the CB1 switch to ON.

6. Turn t he START switch to the right momentarily.

The rectifier turns on, then the inverter turns on. When the inverter reaches full voltage, it turns on and supplies power to the critical load. It takes less than 1 minute for the UPS to achieve Normal mode.

IfabypasssourceisavailablewhenyouturntheSTART switch on, the critical load is immediately supplied by the bypass source in Bypass mode until the inverter turns on and the UPS transfers to Normal mode. The status indicators on the Monitor Panel indicate when the UPS is in Bypass mode and Normal mode.

7. Close battery breaker(s).

To Shut Down the UPS from Normal Mode:

1. Turn t he MODE switch to BYPASS.

The UPS switches to Bypass mode. If the bypass source is not available, the power processor remains on and an alarm sounds.

2. When the transfer is complete (the LCD screen reads “On Bypass”), move the

CB1 switch to OFF.

The bypass source supplies the critical load and the power processor de-energizes. The Bypass mode indicator illuminates on the Monitor Panel.

To Start the UPS in Bypass Mode:

If the power processing unit (PPU) of the UPS is not available and you need to energize your critical load right away, you can energize your critical load without the benefit of backup. To turn the UPS on in Bypass mode:

1. Turn t he MODE switch to BYPASS. (The remaining switches can be in any

position.)

2. Turn t he START switch to the right momentarily.

Power to the critical load is supplied by the bypass source. No backup is available.

To Shut Down Power to the Critical Load While in Bypass Mode:

To perform maintenance or service on your critical load, you must shut it down first:

1. Turn off all equipment that is being powered through the UPS.

2. Press the LOAD OFF pushbutton on the Monitor Panel.

The RMP contains a local horn and the following backlit status indicators:

SYSTEM NORMAL

The UPS is energized (either with utility power or battery back up) and is supplying conditioned power to the critical load.

NO REDUNDANCY

This indicator applies only to parallel systems when one cabinet is not functioning. This feature is not available on this system.

ON GENERATOR

This alarm means that the UPS input and bypass are being supplied by t he power from the generator, instead of from the utility power.

ON BYPASS

Thebypasssourceissupplyingthecritical load. Usually this means that the UPS is not energized. The load is not protected in Bypass mode, and a horn sounds after 30 seconds.

UPS ALARM

The UPS system is issuing an alarm. Conditions that affect the current UPS mode are indicated by the alarm lamps and horn on the U PS.

ON BATTERY

The UPS battery back up is supplying the critical load. The utility power is either interrupted or out of specification. The SYSTEM NORMAL indicator is also lit.

BYPASS UNAVAILABLE

The UPS system is in Normal mode, but

a bypass source is not within specification.

164201036 Rev. D 041500

Battery Cabinets

You can enhance the protection time provided by your UPS by adding one or more battery cabinets. The battery cabinets provided by the UPS manufacturer are equipped with sealed lead-acid, maintenance-free batteries in a cabinet that matches the UPS. Each battery cabinet contains a battery circuit breaker. Several battery capacities are available.

The UPS battery cabinets can be paralleled. With this capability, you can increase your battery backup time by adding battery cabinets to your UPS system. Most UPS models can support up to four battery cabinets.

External Battery Disconnect

A breaker switch is located inside each battery cabinet supplied by the UPS manufacturer. However, due to space limitations, your battery cabinets may not be located in the same area as your UPS. An optional external DC circuit breaker provides a manual means of disconnecting a battery that is located remotely from the UPS. The circuit breaker is enclosed in a wall-mounted box. You can install it anywhere between the remote DC supply and the UPS, according to national and local codes.

The breaker switch should be set to ON for normal UPS o peration when DC power is available at the UPS. When service personnel are performing maintenance on the UPS or battery cabinet, the switch should be set to OFF.

Note 1: There is no DC disconnect device within the UPS.

Note 2: The DC input to the UPS is protected by internal fuses F21 and F22.

Note 3: The UPS DC disconnect trip signal from TB4, points 1 and 2 (shunt trip) or

TB4, points 1 and 3 (UV trip) must be connected to the DC source disconnect device(s).

Locating the Communications Panel

The Communications Panel inside the UPS contains two serial communications ports, one DE---9 and one DB ---25. The ports provide a computer interface to a Remote Monitor Panel (RMP), R elay Interface Module (RIM), or remote terminal and/or printer. The Communications Panel also contains terminals (TB1 and TB2) for connecting your equipment to the UPS. Figure 23 shows the location of these items inside the UPS.

Connecting Equipment to a Serial Port

You can connect a wide variety of terminals, printers, and computers to each port, and configure the UPS as the Data Communication Equipment (DCE). Set up the remote equipment using the appropriate parameters for the mode you select. The following section provides more information about configuration.

The cables you use for connection depend on the equipment you are connecting to the UPS. Cables should be no longer than 16m (50 ft). The connectors for Port 1 and Port 2 on the Communications Panel in the UPS are female, so the cables should be male. Figure 24 shows the pin assignments for Port 1, and Table 2 describes them. Figure 25 shows the pin assignments for Port 2, and Table 3 describes them.

Te r m i n a l m o de System events are logged immediately as they occur.

Calibration Used only by service personnel.

System Config. Allows you to set building alarms, battery tests, etc.

(Check with your Sales or Service Representative for availability.)

Computer Provides a proprietary Binary Computer Mode (BCM) Interface.

Remote Monitor Sends all system event information to an RMP, RIM, or

Supervisory Contact Module (SCM). Available for Port 1 only.

Port 1 and Port 2 cannot be in the same mode simultaneously; they must always be operating in different modes. The modes are described later in this chapter.

The baud rate of the equipment connected to this port. The baud rate determines the speed of data transferred between the UPS and the connected equipment. For Remote Monitor mode, the baud rate must be set to 300. All other modes should operate at the highest baud rate available with the connected equipment. 300 baud is not recommended for any mode except Remote Monitor.

You can select a baud rate of 300, 1200, 2400, 4800, 9600, or 19,200.

Data/Stop

The data size and stop bits of the equipment connected to this port. These settings determine the number of bits transmitted per ASCII character. The data size and stop bits you specify depend on the configuration of your equipment.

For Port 1, the data size must be set to 8, with 1 or 2 stop bits. Settings of 7 data bits/1 stop bit and 7 data bits/2 stop bits are available for Port 2.

NOTE: When connecting a computer running a terminal emulation program, you

should set your equipment to NO PARITY.

Handshaking

This setting controls handshaking. You can select XON/XOFF or Disabled for this setting.

Disabled (No Handshaking)

If handshaking is disabled, the UPS will transmit and receive data via the serial port, ignoring all inputs from handshaking lines.

XON/XOFF

If handshaking is enabled, the UPS uses special characters (XON and XOFF) to handshake with the host terminal. The XON character is defined to be ASCII value 11 hex, and the XOFF character is defined to be ASCII value 13 hex. Upon reception of an XOFF command, the UPS halts transmission until an XON command is received. In the same way, if the terminal receives an XOFF command, the UPS expects the terminal to halt transmission until the UPS sends an XON command.

Save

Set to YES to save any changes to configuration settings upon exit from the Setup screen. Set to NO if you do not want to save any changes.

Default Settings

The following are the default configuration settings for the serial communications ports:

Port 1 Remote Monitor 300 baud 8/1 Handshaking Disabled

Port 2 Terminal 9600 baud 8/1 Handshaking Disabled

Each communications port on the UPS operates in one of five modes which you select when configuring the port using the Setup Port screen.

Term inal M ode

In this mode, system events are continually logged through the serial port to the device connected to the port. Port 2 operates by default in Terminal mode.

The printed log entries contain a time and date stamp and the alarm text message. Terminal mode uses this format for printing alarm entries:

MMM DD HH:MM:SS.hh KYWD MESSAGE :::: <CF> <LF>

Symbol Description

MM Month (3 letters) DD Day (2 digits) HH Hour (2 digits) MM Minute (2 digits) SS Second (2 digits) hh Hundredths of Second (2 digits) KYWD Keyword (ALARM, NOTICE, COMMAND, or STATUS) :::: System Diagnostic Information <CF> Carriage Return Character (ASCII 13) <LF> Line Feed (ASCII 10)

An alarm message is prefixed by the word “CLEAR” whenever an alarm is entered into the Event History Log with a cleared status.

Remote Notification

Remote Notification provides the user with the option of receiving alarms and notices at a remote location. Remote Notification also provides some basic controls that can be performed remotely on the UPS. Remote Notification operates through a standard computer modem. Using the Terminal mode, the user calls the UPS to perform basic monitoring and control. In the event of a UPS alarm or notice, the user is notified at the remote location. The UPS calls, through the modem, to the user’s computer or pager and leaves a message.

Remote Notification is an extension of the Terminal mode with the additional support algorithms necessary to control an external modem (refer to Chapter 7, “Serial Communications”). Connection to the UPS is made when a user calls the UPS on the phone. The user has exactly the same capabilities as if using a terminal connected directly to the UPS RS --- 232 port. Remote Notification differs from the basic Terminal mode with the addition of Call Answer, Call Out, and Housekeeping functions. The Call Answer function allows the user to call into the UPS from a remote location and enter Term inal mode. The Call Out function allows the UPS to be configured to call either a remote computer or numeric paging serviceoverthephoneline. CallOutallowstheUPStocallaremotecomputerand leave a one-line descriptive message of the alarm or notice condition. Numeric paging support allows the UPS to call a paging service and send numeric messages. The Housekeeping function maintains the link between the UPS and modem.

Remote Notification Features

Remote Notification provides the UPS with the capability to utilize a standard off-the-shelf PC modem as a telephone interface. The features provided by this option are as follows:

· Call out to a remote terminal or pager based on programmable events and

alarms.

· Two separate, programmable notification groups (phone numbers).

· Programmable number of redial attempts.

· Programmable time delay between call out attempts.

· Automatic answering (user configurable) for access to the Terminal mode of

the UPS.

· Remote and local ability to clear Call Out alarms and events.

· Error detection and correction for misconfigured and disconnected modems.

· Uses standard modems and cables available at your local computer supply

center.

Description of Operation

The Remote Notification option performs three basic functions: Call Answer into Terminal mode, Call Out to a remote terminal, and Housekeeping. Remote Notification also allows access to any functions available in the Terminal mode from a remote computer or terminal.

Call Answer

To use the Call Answer function, the modem is configured to automatically answer by having the user program the S0 register of the modem to a non-zero number. When the modem receives a call, the UPS is alerted to wait for a connect signal from the modem. When the modem answers and finishes handshaking, the UPS acknowledges the modem connect signal and allows the caller into the Terminal mode (refer to Chapter 7, “Serial Communications”). In this mode, the user can request four items and perform one command:

NOTE: The brackets ([ ]) in the following steps indicate standard keyboard

characters.

· Display all screens (^B, ^M, ^P). Press and hold [CTRL], then press [A].

· Display battery test results by pressing and holding [CTRL], then pressing [B].

· Display meters screen by pressing and holding [CTRL], then pressing [M].

· Display event history by pressing and holding [CTRL], then pressing [P].

· Reset Call Out Alarms by pressing and holding [CTRL], then pressing [R].

The Reset Call Out Alarms command causes the UPS to cease Call Out attempts on a currently active alarm and resets that alarm call. Refer to the “Call Out” section of this chapter for more information.

Call Out

The Call Out function contains programmable alarms and status events (refer to Chapter 11, “Responding to System Events”). The notification groups tell the UPS to notify a remote computer or pager for each selected event. Refer to the “Configuring the Modem” section of this chapter for information on the modem configuration. Refer to the “User-Selected Events” section of this chapter to note which events are designated as group one or two. These events are selected when the UPS is purchased. The Call Out function activates as follows:

· A UPS alarm or notice occurs that is programmed to cause a Call Out.

· The UPS takes the modem off the hook and sends a command to the modem

to call the notification groups (phone numbers) required. The command sent to the modem for group one is “ATDTS0” and “ATDTS1” for group two. This allows the user to program the phone numbers into the modem.

Powerware 9315 (200 kVA ---300 kVA) Operation

164201036 Rev. D 041500

· The UPS logs a successful notify to the event log when the remote computer or

modem answers and leaves an event message with the following format.

nnn<space>mmm<LF><CR> where:

nnn = The telephone number of the UPS (20 characters maximum) <space> = ASCII space character (0x20) mmm = Event message for notice or alarm (40 characters maximum) <LF> = ASCII line feed character (0x0A) <CR> = ASCII carriage return character (0x0D)

If calling a pager service and the service answers, the UPS delays momentarily and then dials the pager number. Refer to the “Configuring the Modem to Call a Numeric Pager” section of this chapter for more information on configuring a modem to dial a pager.

NOTE: Because the pager service is not a modem, the UPS does not know if its

message got through; therefore, the UPS continues to call the pager service for a programmed number of times or until a call-in reset is performed. An unsuccessful notify event is logged into the UPS event log for each attempted call out.

If the phone number that the UPS is calling does not answer, the UPS delays for a time period (programmable from 1 to 60 minutes) and then reattempts the call. If answered, the UPS ceases further attempts to call. Each call group can be programmed for a separate number of attempts to call and delay between calls. Each unsuccessful attempt to call causes an unsuccessful notify event to be logged into the UPS event log.

If both call groups are active, the UPS alternates between calling the groups. The Call Out process can be terminated at any time by calling into the UPS and sending the reset command (press and hold [CTRL] and press [R]) or by turning the key switch on the front of the UPS.

Housekeeping

When the modem is idle, the UPS “pings” (tests for connection) the modem by sending an “AT” to the modem at five-minute intervals. If the modem does not respond correctly, by sending either “O K” or “0” to the UPS, the UPS attempts to re-initialize the modem. After a successful re-initialization, the UPS returns to the Housekeeping function. If the re-initialization is unsuccessful, two more attempts to re-initialize the modem are made before the UPS disables all Call Out attempts. Re-initialization is then attempted every ten minutes or until the communications mode is changed by the UPS front panel controls (or the modem re-initializes). For each unsuccessful attempt, the UPS logs a modem failure event into the event log. When the modem link is confirmed, the UPS communications resume normal operation and Call Out is enabled.

Configuring the Modem to Call a Remote Computer

To configure the modem to call a remote computer, perform the following procedure:

NOTE: Perform this procedure only after completing “Basic Modem Configuration”

section of this chapter.

The brackets ([ ]) in the following steps indicate characters that require keying in prior to pressing [ENTER].

1. Connect the modem to the PC through the serial port as described in the modem manufacturer’s manual .

2. Keyin[A],[T],thenpress[ENTER].

3. Confirm that the modem responds with “OK” or “0” (zero).

NOTE: In steps 4 and 5, the “xxxxxxx” is the phone number of a remote computer.

The phone number should include all local line and long distance access numbers needed to dial out. This number is limited to 32 characters. Placing a “T” at the beginning of the number informs the modem to use tone dialing. For example, use “9” if needed for an outside line, “1” for long distance + (Area Code) + Number or whatever access codes are needed to dial the call directly. Add a “,” in the number anywhere that a delay is needed. This will cause a one-second delay. More than one delay may be added to the number; for example, enter “AT&Z0=T,9,,1 (Area Code) (Phone Number)”.

4. Toprogramagrouponenumber,keyin[A],[T],[&],[Z],[0](zero),[=],[T],[,], [xxxxxxx], then press [ENTER].

5. To program a group two number, key in [A], [T], [&], [Z], [1], [=], [T], [,], [xxxxxxx],

then press [ENTER].

6. Confirm that the modem responds with “OK” or “0” (zero).

7. Keyin[A],[T],[&],[W],[0](zero),thenpress[ENTER].

8. Confirm that the modem responds with “OK” or “0” (zero).

9. Connect a telephone line to the modem and test the modem by keying in [A], [T], [D], [S], [0] (zero), then pressing [ENTER].

10. The modem dials the telephone number stored in step 4 or 5. (The number is

displayed on the terminal screen as it is dialed.) Repeat steps 4 (or 5) through 9 as necessary to modify the telephone number.

Configuring the Modem to Call a Numeric Pager

To configure the modem to call a numeric pager system, perform the following procedure.

NOTE: Perform this procedure only after completing “Basic Modem Configuration”

section of this chapter.

The brackets ([ ]) in the following steps indicate characters that require keying in prior to pressing [ENTER].

1. Connect the modem to the PC through the serial port as described in the modem manufacturer’s manual .

2. Keyin[A],[T],thenpress[ENTER].

3. Confirm that the modem responds with “OK” or “0” (zero).

NOTE: In steps 4 and 5 the “xxxxxxx” is the pager system number and “yyyyyyy” is the

numeric message (usually a phone number). The three“[,]” provide a delay while the pager system computer answers. The “xxxxxxx” entry should include all local line and long distance access numbers needed to dial out, as well as the pause necessary between dialing the pager service and sending the pager the numeric message. This number is limited to 32 characters. Placing a “T” at the beginning of the number informs the modem to use tone dialing. For example, use “9” if needed for an outside line, “1” for long distance + (Area Code) + Number or whatever access codes are needed to dial the call directly. Add a “,” in the number anywhere that a delay is needed. This causes a one-second delay. More than one delay may be added to the number; for example, enter “AT&Z0=T,9,,1 (Area Code) (Phone Number) (Pauses) (Numeric Message)”. For areas with pulse dialing, the “T” should be inserted before the numeric message to switch to tone dialing. The numeric message can only be delivered using tone dialing.

(pound) character at the end of the numeric message is very important. It prevents the pager service from picking up on the modem hang-up commands and sending additional characters.

UPS Setup Configuration

Connect the modem to the UPS by connecting one end of the serial cable to the UPS Port 2 DB--- 25F connector and the other to the modem (refer to Chapter 7, “Serial Communications”). If using a standard serial cable, a null modem adapter is required for the connection to the modem.

The Powerware 9315 UPS can only use serial Port 2, DB---25F, for the Remote Notification option. This connection is located in the serial communications panel at the base of the UPS cabinet, behind the front door.

The modem operates at only one baud rate because there is no handshaking between the modem and the UPS. Select the lowest common baud rate (less than or equal to 2400 baud) compatible with the capability of the UPS interface equipment. For example, if the computer only has a 2400 baud modem, then the UPS should be set for 2400 baud. Remember, the remote computer modem can always slow down to the UPS baud rate, e.g., a 14400 baud modem can run at 2400 baud, but a 2400 baud modem cannot run at 14400 baud.

Following the instructions in Chapter 5, “Using the Monitor Panel” and Chapter 7, “Serial Communications”, use the LCD screen and pushbuttons on the Monitor Panel to access the setup screen and configure Port 2 as follows.

NOTE: The modem should be connected to the UPS as described in the modem

manufacturer’s manual before configuring the UPS communications port.

<MODE> Remote Notify

<RATE> Thebaudrateatwhichthemodemwillcommunicate

to other modems, 2400 baud maximum. <DATA/STOP> 8 1 Standard 8 data bits, 1 stop bit, no parity.

<HANDSHAKING> Disabled

<SAVE> Yes. To save new configuration.

The handshaking feature listed is for UPS-to-terminal handshaking, not UPS-to-modem handshaking. Setting the handshaking to “modem” has no effect. If the remote terminal has buffering problems because of excessive data transfer rate from the UPS, XON/XOFF handshaking can be selected to resolve this issue. The user must make sure that the modem (not the remote terminal) at the remote terminal end of the connection is configured for either hardware handshaking or none at all. This is required so that the modem does not attempt to trap the XON/XOFF characters and prevent them from being t ransmitted to the UPS.

Maintaining the UPS System

The components inside the UPS cabinet are secured to a sturdy metal frame that is supported by the UPS magnetics. This design allows authorized service personnel to remove repairable components with very little disassembly. All repairable parts and assemblies are located in the front of the UPS, allowing all routine maintenance and servicing to be performed with front panel access.

You must schedule periodic performance checks of your UPS to keep it running properly. Regular routine checks of operation and system parameters will enable your UPS s ystem to function efficiently for many trouble-free years.

Important Safety Instructions

Remember that your UPS is designed to supply power EVEN WHEN DISCONNECTED FROM THE UTILITY POWER. The UPS interior is unsafe until the DC power source is disconnected and the electrolytic capacitors are discharged. After disconnecting the utility power and the DC power, authorized service personnel should wait at least 5 minutes before attempting internal access to the UPS system.

WARNING: Servicing and maintenance should be performed by qualified service personnel only.

WARNING: LETHAL VOLTAGE PRESENT. This unit should not be operated with the cabinet doors open or protective panels removed. Do not make any assumptions about the electrical state of any cabinet in the UPS system.

WARNING: Battery cabinet maintenance or battery replacement should be performed by authorized service personnel only. Keep unauthorized personnel away from battery cabinets.

Since each battery cabinet is an energy source in itself, opening the Battery Circuit Breaker does not de-energize the voltage within the battery cabinet. DO NOT

ATTEMPT TO ACCESS ANY INTERNAL AREA OF THE BATTERY CABINET YOURSELF. VOLTAGES ARE ALWAYS PRESENT IN THE BATTERY CABINET.

If you suspect that a battery cabinet needs service, you should contact your local field service office.

If the cabinet requiring service was not provided by the UPS manufacturer, refer to the battery cabinet manufacturer’s operating manual for instructions on battery cabinet installation and maintenance, or contact your local field service office.

Observe these precautions when working on or around battery cabinets:

· Remove watches, rings, or other metal objects.

· Use tools with insulated handles.

· Wear rubber gloves and boots.

· Do not lay tools or metal parts on top of batteries or battery cabinets.

· Disconnect the charging source prior to connecting or disconnecting terminals.

· Determine if the battery is inadvertently grounded. If it is, remove the source of

the ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock will be reduced if such grounds are removed during installation and maintenance.

· When replacing batteries, use the same number of sealed, lead-acid batteries.

· Proper disposal of batteries is required. Refer to your local codes for disposal

requirements.

WARNING: HAZARDOUS WASTE. Do not incinerate or dispose of batteries indiscriminately. Observe local and national codes.

WARNING: Do not dispose of battery or batteries in a fire. The battery may explode.

Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes, and may be toxic.

A battery can cause electrical shock, burn from high short-circuit current, or fire. Observe proper precautions.

Performing Preventive Maintenance

The UPS requires very little preventive maintenance. However , the UPS should be inspected periodically to verify that the unit is operating normally and that the batteries are in good condition.

Perform the following checks DAILY:

· Check the area surrounding the UPS. Ensure the area is not cluttered, allowing

free access to the unit.

· Ensure the air intakes (vents on the front doors) and exhaust opening

(on top of the UPS cabinet) are not blocked.

· Ensure there is at least six inches of clearance behind the unit for proper air

circulation.

· Ensure the operating environment is within the parameters specified in

Chapter 10, “Product Specifications.”

· Ensure the UPS is in Normal mode (Normal status indicator is lit). If an alarm

lamp is lit or the Normal status indicator is not lit, contact Customer Support.

Perform the following checks MONTHLY:

· Ensure all status indicator lamps are operative. (Press the and

pushbuttons simultaneously to test the lamps.)

· Monitor system parameters as described in Chapter 5, “Using the Monitor

Panel.”

· Check the air filters (located behind the front doors) and replace them as

necessary. The filter size is 16 in. x20in. x1in.

· Record the results of your checks and any corrective actions in a suitable log.

ANNUAL maintenance:

Annual preventive maintenance should be performed only by authorized service personnel familiar with maintenance and servicing of the UPS system. Contact your nearest field service office for more information about service offerings.

BATTERY maintenance:

Contact your nearest field service office for battery maintenance. Battery replacement and maintenance should be performed only by authorized service personnel.

monitors itself and the incoming utility power. In Battery or Bypass modes, the UPS may issue alarms to let you know exactly what event caused the change from Normal mode. System events can be indicated by horns, lights on the UPS, or both.

Select Active from the Events menu on the LCD screen to look at the Active System Events screen. This screen shows any currently active alarms, notices, or commands.

System Event Horns

The system event horn beeps according to the type of event it is signifying:

· When the U PS detects an alarm that requires your attention, the horn beeps at

½-second intervals.

· When a notice occurs, the horn beeps at 2-second intervals.

Responding to System Events

System Event Lights

The status indicators on the UPS Monitor Panel work in conjunction with the event horn to let you know when the UPS is operating in any mode other than Normal. Only the Normal indicator is visible during normal UPS operation. The others light to indicate alarms or events. When an alarm occurs, you should first check these indicators to see what type of event has taken place. (For descriptions of the status indicators, refer to the “Reading the Status Indicators” section of Chapter 5.)

Using the LOAD OFF Pushbutton

Load Off is initiated by the covered, red LOAD OFF

pushbutton on the Monitor Panel. This pushbutton is protected by a clear plastic shield to prevent accidental activation. In an emergency, you can press this pushbutton to instantaneously open the input breaker and interrupt UPS output. The UPS is cut off from utility power, and your critical load is de-energized. All power to the critical load is lost. The UPS (including Bypass) remains locked off until you reset the LOAD OFF pushbutton.

WARNING: All power to the critical load is lost when you press this pushbutton. You should use this feature only in an emergency or when you want to de-energize the critical load.

To restart the UPS after pressing the LOAD OFF pushbutton, follow the procedure “Resetting the UPS System after Load Off” of this chapter before starting the UPS.
