Operating Instructions

9.8.2Inserting One Module into a Multi-Module System

This procedure outlines how to integrate a UPS module that has been previously isolated from other modules of a group of paralleled UPS modules. It is assumed that the installation is complete, the sys- tem has been commissioned by authorized personnel and the external power isolators are closed.

!WARNING

Mains voltage will be applied to UPS output terminals.

No operator serviceable parts are located behind covers that require a tool for their removal. Only qualified service personnel are authorized to remove such covers.

1.Open the UPS door to gain access to the main circuit breakers.

2.Open (or confirm disabled) maintenance bypass circuit breaker CB3.

3.Close Input breaker CB1.

The Rectifier indicator flashes on the UPS mimic panel during the startup of the rectifier and becomes steady green once the rectifier reaches normal operation state after about 30 seconds.

4.Close external battery circuit breaker. This breaker is inside the battery cabinet or is otherwise adjacent to the battery racks.

5.After the UPS detects the batteries, the red battery indicator extinguishes when the battery charger starts operation.

6.Close bypass circuit breaker CB2.

7.Press the INVERTER ON control button for 2 seconds.

The inverter will start up and the inverter indicator flashes while it synchronizes to the load volt- age and frequency. After the inverter is ready, the UPS connects to the load, the inverter indicator becomes steady green and the output indicator turns green.

8.Check that no “Warning” message is displayed in the top right corner of the LCD and that the indicators have the status shown below.
