Operating Procedures

In multi-modulesystemsperform each step of the procedure in every UPS module before proceed- ing to the next step.

! WARNING

Mains Voltage will be applied to UPS output terminals.

This procedure results in mains voltage being applied to the UPS output terminals.

 

 

• Isolate and attach warning labels to any downstream load connections, as applicable.

 

 

• No operator serviceable parts are located behind covers that require a tool for 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.

Close Bypass input power switch Q2 and UPS output power switch Q5.

 

Close also any external output isolation switches, where used.

 

The LCD becomes active and after initialization, the UPS output is powered from the bypass,

 

with the bypass and load indicators turned on.

 

The UPS Mimic LED's will indicate (refer to Figure 67):

3.

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.

4.

Close external battery circuit breaker (where an external battery is used). This breaker is located

 

inside the battery cabinet (if used) or is otherwise adjacent to the battery racks

5.

Following battery availability being detected by the UPS, the red battery indicator extinguishes

 

moments after when the battery charger starts operation.

6.

Open (or confirm open) the internal Manual Bypass Power Switch Q3.

 

Open also any external Maintenance Bypass Switch, where used.

7.

Press INVERTER ON button for two seconds.

 

The inverter will start up and the inverter indicator flashes while it synchronises to the bypass

 

voltage frequency.

 

 

 

 

 

After the inverter is ready, the UPS transfers from bypass to inverter, the bypass indicator turns

 

off, and the inverter indicator becomes steady green.

8.

Check that no “Warning” message is displayed in the top right corner of the LCD Monitor and the

 

status of the indicators are:
