The electric chain hoist must be connected in accordance with supplied wiring diagrams.
Remove approximately 3/8 in. (9 mm) of the electrical power cable protective casing to expose
cable. Open the integrated clamp with a narrow blade 1/8 in. (3.5 mm) wide screwdriver, refer to
Fig 1. MHP3318, and install power cable end. Cables (leads) can be identified by color, or in the
case of pendant cables, by numbers taped to each cable. Terminals are identified by letters or
labels on the terminal blocks. Manufacturer-supplied cables have bare wire ends.

Ground (Earth) Connections
The power supply cord includes a grounding (earth) conductor (green wire). Make sure
grounding (earth) conductor is connected to the green/yellow connector terminal.
The ground (earth), green or green/yellow wire, must not carry any power. When hoist is
supplied with a trolley, the power supply is connected at the trolley relay box.
The ground (earth) connection must be wired to the green/yellow ground (earth) connection
terminal. Ground (earth) wire of the terminal power supply is connected to the yellow/green
wire (PE).
Direction of Movement Check
Hoist operation must be in accordance with the control pendant symbols. If hoist does not
operate in accordance with control pendant symbols then hoist is mis-phased. Should this
be the case, switch any two supply power wires L1 and L2.
