NOTICE
When setting the trip point on the electric trip unit, be
careful not to set the trip point too high. Setting the
trip point too high may cause the main breaker not
to trip. This condition could cause serious damage to
the equipment, and serious bodily harm even death to
operating personnel.
Always be conservative when setting the trip point. The
trip setting for this generator is position B 600 amps.
DO NOT adjust the trip point setting when the
equipment is in operation.
