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.

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

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.

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.

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.

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.

startup has been performed by authorized service personnel. The preliminary
startup verifies all electrical interconnections to ensure the installation was
successful and the UPS system operates properly.
Using the Control Panel

Although the Control Panel appears easy to use, you should read these
instructions and thoroughly understand how the controls work before attempting to
use them.
CAUTION:
Incorrect use of the power controls on the Control Panel can cause a loss of
powertoyourequipment.

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.

Using the Monitor Panel
This chapter describes the Monitor Panel and how to monitor and control
UPS operation. The Monitor Panel is a black rectangular area on the front of
the UPS (see Figure 8).
Figure 8. UPS Monitor Panel
The Monitor Panel contains a flat liquid crystal display (LCD) screen (1), a horizontal
row of pushbuttons (2), a vertical column of backlit status indicators (3), and the red
LOAD OFF pushbutton (4). A quick reference label describing how to use the Monitor
Panel is located inside the UPS above the Control Panel. The following sections
describe the Monitor Panel in detail.
