Operation

4.0Scope

Operation describes the start-up for single and parallel units, modes of operation, normal specifications for operating the Galaxy PW™ 100 to 225kVA, including display messages, measurement systems, alarms, batteries, and log time stamping operations.

WARNING

Rectifier/charger start-up is automatic when normal AC input circuit breaker Q1

 

is closed. DC voltage is present in the DC bus.

 

 

4.1Start-up of a Module

Rectifier/charger start-up is automatic when the normal AC input circuit breaker Q1 is closed. The green "rectifier/charger" light 1 on the control panel goes on. Close battery circuit breaker QF1.

4.1.1Start-up of an Inverter

When the rectifier/charger is on, press the "inverter ON" button 7 on the control panel. The green "inverter" light 4 flashes.

4.1.2Emergency Power Off (EPO)

The UPS emergency shutdown function is generally wired to a "mushroom-head" type emergency-off pushbutton. In case of its use, the pushbutton contact has to reset.

IMPORTANT

After EPO/REPO, unit has to be reset by opening M2 feed (switch Q4S). Open

 

switch Q5N also, and then follow the procedure of single UPS for single unit or

 

parallel UPS for parallel units to start-up the system.
