operation. if 440 voltage is required, rewire the
machine per the instructions on
page 49, and fol-
low the circuit requirements on this page.
Amperage Draw

a 2 hp hydraulic pump motor that will draw the
following amps at 440V 3-phase:
Main Motor ............................................ 24 amps
hydraulic pump Motor .............................3 amps
circuit Breaker Requirements
install the machine on a dedicated circuit to
reduce the possibility of overloading the circuit
and tripping the circuit breaker. if the circuit
breaker trips and the circuit is of the correct load
capacity, have the circuit inspected by a qualified
electrician. never use a larger circuit breaker than
stated below, or you will increase the risk of fire.
Circuit Breaker .........................................30 amp
Minimum Wire Requirements
For 440V 3-phase operation, use the following
