ELECTRICAL:
1. Route a copper American Wire Gage (AWG) #0 cable from the battery to the power
unit. Connect one end to the negative battery terminal. Connect the other end to the
power unit’s aluminum valve block with a 5/16”-18 x 3/4” hex cap screw as shown
in Figure 3.
CAUTION: The high current demands of the power unit require a direct connection
between the negative post of the battery and the power unit. Never rely on the
vehicle’s ground circuit, which could lead to property damage or reduced hoist
lifting capacity during peak loads.
NOTE: Avoid routing locations where power cables may rub against any sharp edges of
the vehicle, get pinched or be exposed to excessive heat. Install approved sheathing
over each cable in critical areas.
2.
Route a copper AWG #0 cable from the battery to the power unit - do not connect
the cable to the positive battery terminal until Step 2 of the Fill and Prime section.
Install the provided 250 amp inline fuse no further than 12 inches from the battery.
At the power unit, insert the supplied rubber terminal boot over the end of the cable
and the black wire as shown in Figure 2. Fasten the cable end and black wire to
“Point A” on the solenoid start switch. Tighten to 35 in/lbs torque. Snap rubber
terminal boot over stud to complete connection. Make sure all connections on
solenoid start switch are secure.
WARNING: Never tighten battery cable stud, marked “Point A”, to more than 35 in/lbs
torque and never tighten control stud, marked “Point B”, to more than 15 in/lbs
torque. Exceeding the torque rating for either stud can cause unit to malfunction,
which could lead to property damage, serious injury or death.
3.
(Double-Acting or Single-Acting if equipped) Place the solenoid cover over the
solenoid and secure in place with the tie strap provided.
4.
The hoist should only be used with the operator in a safe location. Locate the hoist
control station in a safe location.
