Connection

WARNING
Before the generator can be connected to a build-
ing's electrical system, a licensed electrician must
install an isolation (transfer) switch in the build-
ing's main fuse box. The switch is the connection
point for generator power and allows selection of
generator or main line power to the building. This
will prevent the generator from charging the main
power line (backfeeding) when the main power
supply has failed or has been turned off for line
repair. Backfeeding can electrocute or injure line
maintenance personnel. Also, generator and build-
7DK-012
ing electrical system damage can occur when nor-
mal operating power returns if unit is used without
an isolation switch.

Extension cord notes

Extension cords should be protected by a tough flexi-
ble rubber sheath (IEC 245) or the equivalent to with-
stand mechanical stresses.
