Operation

Step 2. If the bypass line is not supplied to the SCC, the LCD screen will be blank. Energize the bypass line by operating the following controls:

a.Close the Bypass Input Breaker (BIB). This breaker may be in your Maintenance Bypass cabinet.

NOTE

Wait two minutes after applying bypass power before you operate any other UPS controls.

! CAUTION

DO NOT assume that the UPS System Bypass Breaker (SBB) is closed.

Instructions for operating the Maintenance Bypass circuit breakers are on the Maintenance Bypass cabinet.

Make sure you understand the proper sequence before operating any circuit breaker. Operating a Maintenance Bypass circuit breaker out of sequence could cut off power to the critical load.

Operations involving MIB and MBB MUST only be done when the UPS system is on internal bypass.

b.Ensure the SCC Control Power Disconnect is ON. Open the door to the SCC control section and locate the fuseblock F7 through F10 (see Figure 9). If they are not connected already, push the fuseholders in to turn ON control power, then reclose the SCC control door.

c.Observe the Monitor/Mimic Display screen to determine if your System Bypass circuit breaker (SBB) is closed and whether the UPS Bypass line is supplying power to the critical load.

If your System Bypass circuit breaker is open (as in recovering from an Emergency Power Off or Low Battery Shutdown), close this circuit breaker as follows:

1.Open the SCC control panel door and find the Transfer Relay Board (Figure 11). If the red LED (CR18) labeled TOT S/D (Total Shutdown) is on, press the Bypass Reset switch (SW1) on this board. The red LED should turn off.

2.Set the Static Switch Disconnects (Figure 9) OFF (open), if not off already.

NOTE

Depending on SCC model, the static switch disconnects can be one or two circuit breakers or two contactors. The location could be at the front, right or rear of the cabinet. Refer to the drawing of the SCC cabinet selected for your UPS system.

3.Find the Close Bypass switch (SW1) on the System Interface Board (Figure 11, Item 3). Press this switch to reset the System Bypass circuit breaker. Check the Monitor/Mimic screen to verify the breaker is closed.

d.If currently OFF, close the Static Switch Disconnects.

NOTE

Depending on SCC model, the static switch disconnects can be one or two circuit breakers or two contactors. The location could be at the front, right or rear of the cabinet. Refer to the drawing of the SCC cabinet selected for your UPS system.

4.Press two Reset Switches for Static Switch Disconnects behind door below SCC control panel (see Figure 9). Note that in an SCCT less than 1600A, there is no Reset Switch for the Static Switch Disconnect, so this step is not necessary.

5.Set the Static Switch Disconnects to ON (closed).
