3.4.5Shutdown Procedures System Shutdown Procedure

Perform a System Shutdown Procedure when you want to remove power from the UPS system and System Control 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 610 UPS, observe ALL of the WARN- INGS 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3.Press the ALARM RESET button to clear alarms which are no longer active.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), see 3.4.3 - Load Transfer Procedures. This will open the motorized 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.

Step 3. If maintenance is required in the area of the SCC controls or the motorized system circuit breakers (UPS Output and SBB), transfer the load to the Maintenance Bypass, if available (see 3.4.4 - Maintenance Bypass Load Transfers).

! CAUTION

If your installation does not include a Maintenance Bypass, power must still be isolated from both sides of the UPS circuit breakers if maintenance is required. This will result in loss of power to the critical load. Perform an orderly load shutdown before isolating power.

! WARNING

Lethal voltages are present within this unit even when it is not on or when utility is not being supplied. Observe all cautions and warnings in this manual. Failure to do so could result in serious injury or death. Do not work on or operate this equipment unless you are fully qualified to do so! Never work alone.

Before performing any maintenance on your Liebert Series 610 UPS, observe ALL of the WARN- INGS in 4.0 - Maintenance.
