Galaxy 4000

4.3Post Startup Safety Check List

After initial startup of the system, normal operation should be tested. At the minimum, the following tests should be performed as applicable to your installation.

◗Emergency Power Off (EPO) test.

◗Remote Emergency Power Off (REPO) test (if applicable).

◗Inverter start and stop.

◗Battery transfer test.

◗Maintenance bypass procedure.

CAUTION As soon as AC input power is supplied to the Galaxy 4000 (customer supplied upstream circuit breaker is in the "ON" position), the load is initially supplied via the "Static Switch". Verify that no error indications are present on the operator interface display panel.

4.4Shutdown Procedure

Proceed as follows:

1.Press the gray, Inverter OFF button.

2.Confirm by pressing the function key.

The load is no longer protected by the UPS. It is supplied via the bypass.

3.Set the battery circuit breakers CB1 (in battery cabinet) to the OFF position.

4.Close Q3BP, open input switch Q1, bypass switch Q4S, and output breaker Q5N.

5.To completely remove power from the UPS, open Q3BP and open the upstream circuit breakers supplying AC power to switches Q1 and Q4S. Attention: There is no power to the load.

4.5Shutdown Using EPO

During an emergency situation the UPS and all downstream devices can be instantly shutdown by pressing the red emergency power off (EPO) pushbutton on the front door of the UPS cabinet, or pressing the remote emergency power off (REPO) pushbutton (if applicable) located within the room.

IMPORTANT Pressing the EPO button disconnects the attached load. The emergency power off (EPO) is to be used during emergency situations only, where a hazard to personnel or equipment exists.

4.6Recovery from EPO

To recover from an emergency power off press the EPO pushbutton again. Follow the normal startup procedure in Section 4.2.

NOTE

The EPO pushbutton is a latching device. The EPO condition will remain until the

 

EPO button is depressed a second time.
