System Shutdown Procedure

Perform a System Shutdown Procedure when you want to remove power from the UPS system and System Con- trol Cabinet (SCC) when required for maintenance, or if you need to perform maintenance on a UPS module in a non-redundant system.

Before performing any maintenance on your Liebert Series 600T UPS, observe ALL of the WARNINGS in 4.0 - Maintenance.

Use the SCC Monitor/Mimic Display to determine the operating condition of the UPS system. From the SCC Master Menu, select the Shutdown Procedures screen.

SHUTDOWN PROCEDURES

1.If load is not already being supplied by the bypass line, select the

"LOAD TRANSFER PROCEDURE" screen and follow the instructions to transfer the load to bypass.

2.Go to the modules(s) and follow the module "SHUTDOWN PROCEDURES."

3.Press the ALARM RESET button to clear alarms which are no longer active.

4.If necessary for maintenance purposes, open the static switch disconnect circuit breakers.

5.Wait approximately two (2) minutes before attempting any other action .

Step 1. If the UPS system is supplying power to the load (Load On UPS), select the Load Transfer Procedures screen at the SCC and perform a manual transfer to the bypass line (Load On Bypass). This will open the motor- ized UPS Output circuit breaker (see Figure 9) and close the motorized System Bypass circuit breaker (SBB, Figure 9).

Step 2. If maintenance is required on the Static Bypass Switch, set the Static Switch Disconnects to OFF (open). Refer to Figure 9.

NOTE

Depending on SCC model, the static switch disconnects can be two circuit breakers, contactors, or plug-in connections on a drawout carriage assembly. 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.

CAUTION

The UPS bypass line is still energized.
