This generator must be connected to an automatic
transfer switch. The automatic transfer switch detects
when a power failure occurs and automatically starts the
engine to provide generator power. When the utility
power becomes available, the transfer switch
automatically shuts down the generator and switches
back to the utility power. (See figure 1 for typical
installation).
Refer to the transfer switch manual for detailed
installation and safety instructions. Comply with all the
instructions in the manual along with the labels and tags
attached to the transfer switch.

• Hazardous "backfeed" voltage can cause
severe injury or death. Install a transfer switch
in standby power installations to prevent
connection of standby and other sources of
power. Electrical backfeed into a utility
electrical system can cause serious injury or
death to utility personnel working on
transmission lines.
• Do not try MANUAL operation of the transfer
switch until all power supplied to the switch has
been positively turned OFF. Failure to turn OFF
power supplied may result in extremely
dangerous and possibly lethal electrical shock
or arching.
