AC

Rackmount Pure Sine Wave inverters feature IGBT (Insulated Gate Bipolar Transistor) technology, minimizing
weight and dimension, while enhancing output short circuit reliability and overload capacity.

Output voltage is provided in one of two ways:

1) From AC input bypass mode: (Off-Line Mode)

2) From DC to AC inverter mode: (On-Line Mode)

Either mode is front panel programmable; the selected operational mode will predetermine the “default” output.

In the first option, Off-Line mode

, AC output power will be supplied through the AC bypass mode in its “normal”
operation. Upon AC input failure, output power will be diverted through the DC to AC inverter mode. Once AC mains
are restored, the unit will revert from inverter mode to bypass mode.

In the second option, On-Line mode

, AC output power will be provided directly by the inverter from the VDC source.
Should the DC source or inverter fail, the system will transfer its output power through the bypass mode. Once the
DC power source is restored, the system will revert to “inverter” mode.

Transfer time from inverter to bypass, or bypass to inverter is < 4 ms.

The Off-line/On-line mode is changed from one to the other by pressing the ON button for less than 3 seconds when
normal

output is available. The operational mode cannot be changed during an abnormal or fault condition.

¾ ON/OFF buttons:

These are the two power buttons for turning on or turning off the inverter.

Once the inverter is on, the “ON” button works as the On-Line <=> Off-Line mode switching button.

¾ INVERTER ON Indicates the INVERTER has been turned on and is working normally (output is available to

support load equipment).

¾ OVERLOAD Means that the inverter is in overload condition, or that there is an output short circuit.
¾ DC ABNORMAL Means that the input DC voltage is “abnormal” and requires verification.
¾ FAULT Indicates that the inverter is in “fault” condition. See Section 6-3 Alarms

**If utility by-pass is not being used, and AC input is not present, the fault LED will remain on.

¾ LCD Display Selection Buttons

The following data: (output voltage, output frequency, load, input dc voltage, bypass ac voltage, bypass ac
frequency, etc.) and system status can be shown sequentially on the LCD display by pressing these two buttons.
For more information – Refer to Section 5 Operation

¾ Ventilator

The ventilator on the front panel provides inverter cooling. Do NOT

obstruct this vent or the fan exhaust in the

back of the unit!

¾ Circuit Breaker (DC Input Breaker)

The DC circuit breaker will be tripped if there is a “short circuit” condition within the inverter. Reverse polarity
protection (input) and overload protection are integrated within the internal circuitry and neither of these faults
should trip the DC breaker.

4-3 Installation Tool Kit

Contents of the tool kit include:

• Poly zip bag containing twelve M4 screws and two 6-32 screws,

• Two large mounting brackets (23” or 24” rack mount),

• Two small mounting brackets (19” rack mount),

• One protective cover for AC input,

• One RS232 Cable.

4-4 Locking Hardwire Adapter

¾ The optional adapter is a reliable locking NEMA 5-15 plug on one end and terminal screws on the other end.

The plug-to-terminal conversion is used to secure bare wire load circuit wiring to the output sockets of the

inverter. The adapter includes strain relief for the wires being connected to the terminals.
Documents Also Available: Application Note # AN-001

5. OPERATION

5-1 Connecting to the Input Power

¾ Turn off the DC breaker before connecting the DC voltage to the input terminal. The DC terminal strip will

accommodate ring terminals with wire sizes recommended in Chapter 4-2.

¾ NOTE: Sparks will occur if the breaker is “on” when connecting the input DC voltage. This is a normal condition

due to the charging current draw from the DC voltage charging the internal capacitor of the inverter.

¾ Once the DC power has been connected, engage the DC breaker to operate the inverter.

5-2 Connecting the Loads

¾ Calculate the total power consumption (VA) of the load being attached to the output. Make sure that the total

power consumption does not exceed the rated load of the inverter.

¾ The load consumption can be monitored on the front screen of the inverter using the data button.

¾ Should the total load exceed the capacity of the inverter, remove uncritical loads until the total load is within the

capacity of the inverter. Distribute removed loads to alternate sources or additional inverters

7. COMMUNICATION

7-1 Dry Contact Communication Terminal

The “Dry Contact” terminal is the interface for two Form C relays. The relays are used for switching the voltage
provided by the user’s external alarm system.

One contact set is for “DC Abnormal” and the other one is for “FAULT”. When alarms in each classification
trigger, the relay switches state. (Ref: Sec. 6-3 Alarms) Connection to the terminal should be made to external
sensor circuits with appropriate sized wire. The terminal can support 5A / 250VAC in either NC or NO
configurations.

¾ NC: Normally Closed
¾ CO: Common
¾ NO: Normally Open

7-2 SNMP Expansion Card Slot (WEB)

Remote monitoring is a prime consideration and requirement to manage multiple network elements from a central
location. SNMP remote access as easy as; installing the plug-n-play card, configuring your network IP address, and
attaching the network interface cable.

The SNMP Kit includes:

¾ Interface electronics card
¾ Cover plate
¾ RS-232 to RJ-45 custom cable
¾ Quick installation guide
¾ CDROM with utilities and MIB

The integrated expansion card slot is located on the rear of the inverter behind a protective cover plate. [Ref: 3-4 Rear
Panel] Installation of the SNMP card and cover plate is easily achieved using a standard #2 cross point screw driver.
Card IP address programming required PC interface. Instructions for installation are included in the kit. (kit sold
separately)

7-3 RS-232 Communication Port (GUI)

The RS-232 communication port provides the following features using a GUI software package:

1) Communicates Fault, DC abnormal, Overload, Inverter Fail etc.

2) Monitor and display output voltage, output load, input dc voltage and temperature.

3) Coupled with PC software application port, provides scheduled on/off function for inverter.

Inverter data will be transmitted at 2400 baud rate. Signal is 8 bit, 1 stop bit, and no parity bit.

All information is provided in GUI format and intended for local maintenance monitoring.

9. Optional Hardware:

SNMP Remote Communication Card

:

Remote monitoring is a prime consideration and requirement to manage multiple network elements from a central

location. Remote access is established by simply installing the plug-n-play card, configuring your network IP

address, and attaching the network interface cable.

Locking - Hardwire Adapter

:

Reliable locking NEMA 5-15 plug to secure load circuits to the output sockets of the inverter. Heavy-duty design

locks the plug in place to prevent disconnecting critical loads.

[Note: Only two hardwire adapters will fit on the integrated NEMA duplex outlets of the inverter. Loads should be distributed so not to exceed current

ratings of hardware and cable.]
