fitted: 
•  Refer to the Wire Size Tables on page 16
 and local wiring rules, and 
select the correct size ac cable. 
•  Terminate the cables with M4 crimp lugs. 
•  Route the cables to the ac neutral, ground and line terminal studs 
through the left-side panel. 
4  Secure the connections with the screws and washers supplied. Tighten the 
screws according to the Standard Torque Settings on page 58
. 
 
Step 6 - Connect ac output cables (if required) 
 
 
Ignore this Step if a static transfer switch (STS) or a maintenance bypass switch 
(MBS) is fitted. 
1  Refer to the Wire Size Tables on page 16
 and local wiring rules, and select 
the correct size ac cable. 
2  Terminate the cables with M4 crimp lugs. 
3  Route the cables to the ac neutral, ground and line terminal studs through 
the left-side panel. 
4  Secure the connections with the screws and washers supplied. Tighten the 
screws according to the Standard Torque Settings on page 58
. 
  Do not connect the other end of cables to ac load equipment at this stage. 
 
Step 7 - Connect inverter alarm (if required) 
 
 
  CN11 on the inverter shelf backplane is the inverter alarm. It will send out 
alarm signal if either inverter in the shelf fails. 
This alarm is typically used if the inverters are stand-alone (no controller). 
If required, connect from CN11 to a suitable digital input of an external alarm 
monitoring system. See details on page 57
.
