Note
In this manual, nominal voltages are used when referring to power
supply systems. However, with no modification, the Shopstar
Hoist will operate on a range of voltages as indicated below:

THREE PHASE HOISTS
Since the motor in a three phase hoist can rotate in either direction,
depending on the manner in which it is connected to the power
supply, the direction of hook movement must be checked during
the original installation and each time hoist is moved to a new
location as follows:
1. Move the manual disconnect switch handle to the
“OFF” position.
2. Connect the BROWN, GREY AND BLACK wires of hoist
power cord to load side of disconnect switch. Connect
the GREEN-YELLOW wire of hoist power cord to power
supply ground.
3. Move the manual disconnect switch handle to the
“ON” position.
4. Depress the (up) control. If the hook moves in the up direction,
the hoist is ready for operation. If the hook lowers, move
the disconnect switch handle to the “OFF” position and
interchange the BLACK and BROWN leads at the disconnect
switch. Move the disconnect switch handle to the “ON”
position and the hoist is now ready for operation.
CHECKING FOR ADEQUATE VOLTAGE AT HOIST
The hoist must be supplied with adequate electrical power for proper
operation and to reduce problems that may result from insufficient
power (low voltage). These include:
• Noisy hoist operation due to brake and/or contactor chatter.
• Heating of the hoist motor and other internal components as well
as heating of wires and connectors in the circuit feeding the hoist.
• Failure of the hoist to lift the load due to motor stalling.
• Blowing fuses or tripping circuit breakers.
• Dimming of lights or slowing of motors connected to the
same circuit.

For proper operation and to avoid these low voltage problems,
voltage (measured at end of the power cord while lifting rated load)
should be as the following chart indicates.

*The drop in voltage upon energizing the hoist should not be below the value listed.
Low voltage can also be caused by using an undersize extension
cord to supply power to the hoist. The following charts should be
used to determine the size wires in the extension cord in order to
minimize the voltage drop between the power source and the hoist.

After the hoist is suspended from its support and you have made
sure the power supply complies with the above, the hoist is ready
for operation.
On the Double units, cut and discard the ties used to hold the two
strands of chain together. With no load on the lower hook, depress
the UP button in the control station and raise the lower hook
until it is about 2 feet below the bottom of the hoist. Check both
strands of chains for twists. Twists occur if the lower hook block
has been capsized between the strands of chain during packing,
shipment and/or handling. Reverse the capsize to remove twists.
