Operation

3.2.9Shutdown Procedures Screen

Go to the Master Menu and move the cursor to SHUTDOWN PROCEDURES. Press the Select pad and the Shutdown Procedures screen is displayed.

This two-page screen contains the steps you must follow to perform a controlled shutdown of the UPS system. The instructions are listed so you can review them before performing the controlled shutdown.

To perform the shutdown procedure, transfer the critical load from the UPS system to the bypass line. Then open the battery circuit breaker and manually open the UPS input circuit breaker. The Control Power may be turned off (by pulling open the two fuseholders labeled Control Disconnect) if required for maintenance purposes.

Refer to 3.4.4 - Shutdown Procedures for more details, including module shutdowns for service and emergency shutdowns.

SHUTDOWN PROCEDURES (Cont'd)

6.If necessary for maintenance purposes, open the static switch disconnects and/or control power switch (fuse disconnect on some models) to the OFF position.

7.Wait a minimum of two (2) minutes before attempting any other action.

3.2.10Battery Time Screen

At the Master Menu, move the highlighted cursor to BATTERY TIME. Press the Select pad and the Battery Time screen is displayed.

When AC power is not available to the UPS module, the UPS inverter uses DC power from the battery to supply the critical load. This screen helps the operator assess his power resources to determine if and when the critical load shutdown procedures need to be started.

The Battery Time screen is a line graph that tracks the present battery voltage versus the elapsed time that the battery has been discharging (Figure 35). As the battery voltage decreases, the line representing it moves closer to intersecting the line that represents the battery shutdown voltage.

When the battery starts to discharge, the screen displays a 15-minute graph. If the battery has been providing power for more than 15 minutes, the screen displays a 30-minute graph. If battery power is still available after 30 minutes, a 60-minute graph is displayed (Figure 36).
