Installation Manual

2-2. Block Diagram

The inverter features IGBT technology which, minimizes weight and dimension,

while enhancing output short circuit reliability and overload capacity.

AC output voltage is provided in one of the two following modes

1. From DC to AC Inverter Mode (On-line Mode)

2. From AC Input Bypass Mode

(Off-line Mode)

Either mode is front panel programmable.

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 the Inverter Mode to the Bypass Mode.

In the second option, On-line mode, AC output power will be provided directly by the

inverter from the DC 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 the inverter mode.
