•The 120VAC supply to the battery charger is switched OFF.

‹PREPARATION FOR START-UP

•Ensure that the 120VAC circuit breaker to the bat- tery charger is open.

•Remove the fuse from the the control panel. For the H-100 and R-series: 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- tor. Ensure each plug is seated correctly and fully inserted into its receptacle.

•Verify the AUTO/OFF/MANUAL switch is in OFF position.

•Open the valve to the engine fuel line.

•Bleed the fuel system of air. (necessary for long fuel lines).

•Open the generator main line circuit breaker.

•Connect a manometer to the gas line and record the static pressure. It must be as listed in the Specifications.

•Insert the fuse into the control panel.

•Move the AUTO/OFF/MANUAL switch to the MAN- UAL position. The engine should now crank and start.

•Check voltage at the generator terminals.

•For 3-phase units, check phase rotation at the transfer switch terminals. The generator phase rotation must match the utility phase rotation.

•Check for coolant, fuel, oil, and exhaust leaks.

•Close the generators main line circuit breaker.

•Turn the generator set off.

•Connect the UTILITY supply to the transfer switch.

•Set the AUTO/OFF/MANUAL switch to AUTO.

•Disconnect utility power before the transfer switch.

Engine should start, transfer to load.

Run at least 15 minutes on generator power. Make certain all 3-phase loads are functioning correctly (correct phase rotation).

•Reconnect Utility power

Transfer switch will transfer back to Utility and engine will shut down within the given time parameters set up for the specific transfer switch and controller.

•Install all covers, access plates and door panels.

•Put the Owners Manual in a safe and accessible place.

•Make certain the AUTO/OFF/MANUAL switch is in the AUTO position.
