DANGER

Hazardous voltage.

Will cause severe injury or death.

This equipment must be installed and

serviced by qualified electrical per-

sonnel.

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.

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 the connection

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.

* The wire size for 60_C (140_F) wire is not required to be included in the marking. If included, the wire size is based on ampacities for the

wire given in Table 310-16 of the National Electrical Coder, in ANSI/NFPA 70, and on 115% of the maximum current that the circuit carries

under rated conditions. The National Electrical Coder is a registered trademark of the National Fire Protection Association, Inc.

NOTICE

Canadian installations only. For standby service connect

the output of the generator set to 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.

The electrical installation must comply with the National

Electrical Coder (NEC) class 1 wire designation and all

applicable local codes. Canadian installations must

comply with the Canadian Electrical Code (CEC) and

applicable local codes.

AC circuit protection. All AC circuits must include

circuit breaker or fuse protection. The circuit breaker

must be rated for a maximum of 125% of the rated

generator set output current. The circuit breaker must

open all ungrounded connectors. The generator set is

equipped with a factory-installed circuit breaker.
