To avoid an unbalanced load which may damage the trolley, the hoist must be centered
under the trolley.
Trolley wheels ride on the top of the lower flange of the beam.

Power Connection

Electrical connection adjustments should only be performed by authorized specialists.
The main connection cable, fuse and the switch must be installed by the customer before connecting
the electric chain hoist to the mains power supply.
A 4-wire cable with a ground protective conductor is needed to provide the power supply for three-
phase models. A 3-wire cable with a protective conductor is adequate for single-phase models. The
length and the gage must be determined to support the power consumption of the electric chain hoist.
The ground conductor must not carry any power. With motorized trolley operation, the
power supply is enclosed in a terminal box on the drive motor. With the installation of a
motor protector, the load plate voltage of the electric chain hoist must be noted.
Checking direction of rotation: If the direction of rotation does not correspond with the
button symbols on the control switch, power supply wires L1 and L2 must be swapped
around.
Electrical Connections if not tight and secure, will cause a fire. During installation the
electrician must make sure that all electrical connections including the ground connection
are secure. Make sure all junction boxes and switch enclosures are adequately sealed and
protected for the environmental conditions to be encountered.
Make sure wire connection at the terminal is in accordance with Fig 1. MHP3318.
