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.
