Installation and User Manual

4.2Normal Startup Procedure

With all of the initial safety check lists verified, the Galaxy 4000 UPS system can now be powered.

The following startup procedure should be performed during the initial startup following installation and commis- sioning of the system (typically by a MGE Field Engineer), and this sequence should be followed any time that the Galaxy 4000 UPS is being restarted from an off condition (i.e., after the UPS has been powered down by removing the upstream AC input power and opening all the circuit breakers of the UPS). For device locations refer to Figure 4-1.

a.Apply power to the UPS bypass by closing the upstream circuit breaker supplying Q4S (mains 2).

b.Apply power to the UPS input by closing the upstream circuit breaker supplying the main AC input Q1 (mains 1).

c.Close the maintenance bypass switch Q3BP in the UPS cabinet or in an external cabinet if present. Power is now available at the UPS output (the load is energized) via maintenance bypass.

d.Close the bypass switch Q4S. The static switch will come on-line; the fans will start and the display will illuminate.

e.Close the output isolation circuit breaker Q5N.

f.Open the maintenance bypass switch Q3BP in the UPS cabinet or in an external cabinet if present. The load is now supplied via the static bypass.

NOTE

IMPORTANT

If your UPS configuration does not include the maintenance bypass option, startup requires only closing Q4S and Q5N to supply the bypass source to the attached load.

If the UPS is programmed for automatic restart the inverter will automatically start.

g.Close the input switch Q1. Verify that the following conditions exist:

–The red “load not protected” LED is on.

–The rectifier automatically starts.

If either condition is not present, there is a fault. Open Q1 and contact MGE Field Services.

h.Close the battery disconnect circuit breakers CB1. The batteries are now connected to the battery charger, and have begun charging.

i.If the UPS is programmed for manual restart, press the “inverter on” green pushbutton.

j.The UPS will automatically transfer the load to the UPS inverter output. The green “load protected” LED will turn on and remain on.

k.Close the optional output distribution circuit breakers (if present).

NOTE

If the transfer conditions are not satisfied (bypass AC input source is out of

 

tolerance, or some other reason), a forced transfer is required.
