OFF position.

11. Reconnect the generator set engine starting

battery leads, negative (--) lead last.

12. Reconnect power to the battery charger.

13. Start the generator set by moving the generator set

master switch to the RUN position.

14. Check for leaks using a gas leak detector.

15. Move the generator set master switch to the OFF/

RESET position to shut down the generator set.

To convert from LP vapor to natural gas, remove the fuel

1.8 Electrical Connections

Hazardous voltage.

Backfeed to the utility system can

cause property damage, severe

injury, or death.

If the generator set is used for

standby power, install an automatic

transfer switch to prevent inadvertent

interconnection of standby and

normal sources of supply.

WARNING

Grounding electrical equipment. Hazardous voltage can

cause severe injury or death. Electrocution is possible

whenever electricity is present. Ensure you comply with all

applicable codes and standards. Electrically ground the

generator set, transfer switch, and related equipment and

electrical circuits. Turn off the main circuit breakers of all

power sources before servicing the equipment. Never contact

electrical leads or appliances when standing in water or on wet

ground because these conditions increase the risk of

electrocution.

Electrical backfeed to the utility. Hazardous backfeed

voltage can cause severe injury or death. Install a transfer

switch in standby power installations to prevent theconnection

of standby and other sources of power. Electrical backfeed

into a utility electrical system can cause severe injury or death

to utility personnel working on power lines.

NOTICE

Canadian installations only. For standby service connect

the output of the generator set t o a suitably rated transfer

switch in accordance with Canadian Electrical Code, Part 1.

Have an authorized distributor/dealer or a licensed

electrician make the following electrical connections.

Verify that the electrical installation complies with the

National Electrical Code (NEC) and all applicable local

codes. Ground the generator set from the GRD terminal

inside the controller compartment according to

applicable codes.

1.8.1 AC Connections

The generator set is equipped with a field-connection

terminal block located in the air inlet area near the

junction box. See Figure 1-19 and Figure 1-20. Also

see Section 2, Wiring Diagrams.

Refer to the transfer switch specifications and

Figure 1-20 for the acceptable cable sizes. Route AC

leads through flexible conduit. Ensure that the leads

and conduit do not interfere with the operation of the

generator set or obstruct the service areas.

The electrical installation must comply with the National

Electrical Code (NEC) and all applicable local codes.

Connection Procedure

See Figure 1-20. Leads have been factory-installed

from the junction box to the terminal block for easier field

wiring. Refer to the decal near the terminal block for

connections.

1. Connect the leads from the transfer switch

emergency source lugs to the L1 and L2

connections on the generator set terminal block.

2. Connect the neutral (L0) and ground (GRD) leads

from the ATS and the main panel to the

corresponding connection points on the terminal

block. See Section 1.8.3, Grounding.

3. The terminal block kit includes 120VAC

receptacles for the battery charger and optional

carburetor heater. Connect utility power to the

terminal block as shown. Connect to a circuit that is

supplied by the generator set if utility power is lost.
