DANGER!
HIGH VOLTAGE!! Disconnect and/or lock out the electrical supply to
the power unit prior to any maintenance being performed.
INTERNAL POWER UNITS
Because Autoquip "Super-Torque" motors actually deliver substantially more
horsepower than their nameplate rating, they must always be wired for heavier current-
draw than standard motors of the same nameplate rating. However, because of the
starting efficiency and superior running characteristics of the "Super-Torque" motor,
circuit components do not have to be as large as for standard motors of equal delivered
horsepower.
The following chart should be referenced in connecting these motors to power sources,
remembering that, where 115-Volt operation is contemplated, the current-draw is too
heavy for plugging into ordinary lighting circuits. Heavy wire must be used all the way to
the power-source.
3/4 HP / 1 PH 115 Volts 230 Volts
Full Load Amperages 16.6 AMPS 8.3 AMPS
NOTE: 115V/1ph/60Hz operation is not recommended. If 115V/1ph operation is
absolutely required, the lift will function properly if adequate power is supplied.
However, it is very sensitive to deviations from the required power.
Consequently, performance could prove unsatisfactory. To assure proper
operation on 115V/1ph/60Hz power supply, a separate circuit, protected by a 30
AMP time delay circuit breaker, and adequate wiring should be provided to allow
and actual 115V at the power cord plug during fully loaded operation. Specify if
required.
REMOTE POWER UNITS
1. The “vertical” unit utilizes a 5 hp / 208-230 volts / 60 hertz / single phase motor
coupled to a high-pressure positive displacement gear pump and Autoquip
Corporation’s patented Deltatrol valve assembly. It is also available with a 5 hp /
230 or 460 volts / 60 hertz / three-phase motor as an option.
