Operating Procedures

7.8Insertion of One Module in a Multi-Module System

This procedure is indicated to reintegrate 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 authorised to remove such covers.

1.Open the UPS door to gain access to the main power switches.

2.Open (or confirm disabled) maintenance bypass power switch Q3

3.Close input bypass power switch Q2 and UPS output power switch Q5.

(Close also any external output isolation switches, where used). The LCD display becomes active.

4.Close the Rectifier AC Input Power Switch Q1.

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

5.Close external battery circuit breaker QF1 (where an external battery is used). This breaker is located inside the battery cabinet (if used) or is otherwise adjacent to the battery racks

6.Following battery availability being detected by the UPS, the red battery indicator extinguishes moments after when the battery charger starts operation.

7.Press INVERTER ON button for two seconds.

The inverter will start up and the inverter indicator flashes while it synchronises to the load volt- age 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 Monitor and the status of the indicators as follows:
