Figure 3-3 Coiled Control Cable and Power Supply Cable Connections
3.5.6 Connection to Electrical Power Source - The red, white, and black wires of the Power Supply Cable
should be connected to an Electric Power Disconnect Switch or Circuit Breaker. This connection
should be made so that the hoist is phased properly. Refer to
Section 3.7.11 of the ER2OM for
instructions on how to check for correct power supply phase connection.
3.5.7 Fuse/Breaker Capacity -The hoist's power supply should be equipped with overcurrent protection such
as fuses, which should be selected for 110% to 120% of total listed full load amperage, and should be
dual element time-delay fuses. Refer to the motor nameplate for the full load amperage draw.
3.5.8
DANGER
Grounding - An improper or insufficient ground connection creates an electrical
shock hazard when touching any part of the hoist or trolley. In the Power Supply Cable the ground wire
will be either Green with Yellow stripe or solid Green. It should always be connected to a suitable
ground connection. Do not paint the trolley wheel running surfaces of the beam as this can affect
grounding.
