WARNING

The power shelf must be connected to 120 V AC and a 20-ampere circuit. The AC receptacle must be rated 20 amperes and wired with #12 AWG. Non-conformance to these requirement may cause the AC breaker/fuse at the AC distribution cabinet to open, under certain operational conditions, resulting in loss of power for both rectifiers.

Input AC:

120 V AC/18 A

Power system maximum load:

6 A typical to 10 A maximum.

Battery charging current:

7 to 11 A, depending on power system

 

load.

Maximum battery reserve:

120 AH (based on 8 hours).

Delayed Start delay:

Two positions; 12 and 24 hours (12

 

hours for 6 A load application and 24

 

hours for 10 A load applications).

 

Factory delayed start setting: 24 hours
