ELECTRIC WIRE ROPE HOIST
XM SERIES
After that, fasten the supplied clamps to the
free rope end.
3.8 ELECTRICAL EQUIPMENT
Caution: before starting assembly and start-up
of the electric hoist, visually check there are no
mechanical or other damages caused by transport.
Connection to the power supply line for hoists with
electric equipment
First of all, check if the rated voltage and
frequency on the identification plate of the
hoist comply with the power supply line values.
After that, perform the connection and start-
up of the electrical hoist observing the wiring
diagram located inside the electric equipment.
If the feeding cable of the hoist does not form
part of the delivery, determine its sections in
mm
2
taking into account the necessary length
and the current consumption of the motors,
refer to section 3.10 "Start-up" on page 41.
3.9 CONNECTING THE HOISTS
WITHOUT EQUIPMENT TO ELECTRICITY
Before switching on the hoist motor, check if
the voltage and the frequency of the network
power supply line comply with the data on the
identification plate of the hoist. Considering that
bipolar motors generally have only one feeding
voltage, it is impossible to change the voltage
inverting the connection in the terminal box.
Verify that, under worst operating conditions
(i.e. with the greatest number of users
operating), and with the hoist at full load,
The voltage at the motor terminals remains
within a tolerance of ± 10% of the rated voltage.
Forcefully tighten the terminals in order to
avoid loose contacts.
Make sure that the wiring diagram of the
electric system of the terminal box refer to the
installed hoist.
Define the capacity of the fuses according to
the amperage of the electric motors on the
hoist and trolley (Tab. 2-2A-3-4-5 on page 40).
Determine the section in mm
2
of the feeding
cable, taking into account the necessary length
and the current consumption of the motors
(Tab. 6 on page 41).
For rapid closing of the brake for cylindrical
lifting motors with power over 8 KW, 2 auxiliary
contacts must be installed on the up/down
switches in the electric control panel, in
order to cut off the CC on the brake, as in the
enclosed diagrams.
