HIGH VOLTAGE!! – Disconnect and/or lock out the electrical
supply to the power unit per OSHA Lock-Out, Tag-Out
procedures prior to any installation or maintenance being
performed.
POWER UNIT
CONTRACTOR REMOTE POWER UNIT:
1. The Contractor Power Unit utilizes a 5 HP / 208-230-460 Volt / 60 hertz / 3 phase
“Super-Torque” intermittent duty motor with (one full lift cycle per 2 minute
period) driving a high pressure positive displacement pump assembly with an
internal relief valve, check valve and down solenoid valve.
2. Because
Autoquip "Super-Torque" motor actually delivers substantially more
horsepower than the nameplate rating, it must always be wired for heavier
current-draw than standard motors of the same nameplate rating. However,
because of the "Super-Torque" motor’s starting efficiency and superior running
characteristics, circuit components do not have to be as large as for standard
motors of equal delivered horsepower.
VERTICAL REMOTE POWER UNIT:
1. The Vertical 'HD' Power unit utilizes a 5 HP/ 208-230-460 Volt / 60 hertz / 3
phase Heavy Duty motor, (with a 30 minute continuous duty rating). The power
unit is coupled with a high-pressure positive displacement gear pump, and
Autoquip Corporation’s patented Deltatrol valve assembly.
2.
The vertical power unit is also available with a 5 HP/ 230 Volt/ 60 hertz / 1phase
motor or a 3 HP/ 115 Volt / 60 hertz/ 1phase motor as an option. These motors
are not Super Torque motors. These motors coupled with a high-pressure
positive displacement gear pump, and Autoquip Corporation’s patented Deltatrol
valve assembly.
3.
The motor connection diagram in Figure 21, should be referenced in connecting
the motors to a power source. Remember that heavy wire must be used all the
way to the power source.
