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 sup-
ply has failed or has been turned off for line repair.
741-104
Backfeeding can electrocute or injure line mainte-
nance personnel. Also, generator and building
electrical system damage can occur when normal
operating power returns if unit is used without an
isolation switch.

EXTENSION CORD NOTES

Extension cords should be protected by a tough flexible
rubber sheath (IEC 245) or the equivalent to withstand
mechanical stresses.
