•  Communication wires connected between transfer 

switch and generator (HTS only).

•  Unit secured to pad.



• The AUTO/OFF/MANUAL switch is in the OFF 

position.

• The 120VAC supply to the battery charger is

•  Remove the fuse from the the control panel. Open 

the front door of the control box and remove the 
15 Amp ATO fuse in the lower left-hand corner of 
the control box.

• Connect the battery cables to the battery. Attach 

negative battery cable last.

• Close the 120VAC circuit breaker to the battery 

charger.

•  Measure the voltage at the battery before and after 

the charger is turned on.

•  Verify all AC electrical connections are tight at the 

circuit breaker and transfer switch.

•  Visually inspect entire area looking for loose paper, 

plastic wrappings, leaves, etc.

• Check all hoses clamps fittings for leaks or dam-

age.

• Check all electrical plugs throughout the genera-
