Electrical Installation
The operator must furnish 460 VAC, 3-phase, 60 Hz electric power to the enclosure on the Hydraulic Power Unit.
The power supplied must be sufficient to power a 30 HP motor and a 4.5 KW heater. The proper wire size must be
selected, taking into consideration the amperage carried and the length of run. See Figure 6-9 for penetration details.
The electrical enclosure does not include a master switch for the high voltage input. It is suggested that a master
switch be installed within line-of-sight of the unit. Local electrical codes may require different electrical connections, and
it should be verified that the system is in accord with these codes.
WARNING CAUTION
IT IS IMPERATIVE THAT THE PROPER ROTATION OF THE MOTOR AND PUMP BE
ESTABLISHED AS INDICATED ON THE MOTOR HOUSING. Serious damage to the pump will
occur if it is operated in reverse. The direction of rotation can be checked by "jogging" the
motor on and off very quickly. If necessary, any two wires of the 3 phase input can be switched
to reverse the direction of rotation.
THESE ELECTRICAL CONNECTIONS SHOULD BE MADE BY QUALIFIED AND KNOWLEDGEABLE
PERSONNEL ONLY. After the connections are made close and secure the enclosure. Do not
reenter the enclosure until it is positively determined that the power has been disconnected.
