3.6 Main switch
In contactor control a main switch is included.
3.7 Main current fuses / Feed cable / Circuit diagrams
The connection of the wire rope winch always has to be effected according to circuit and wiring di-
agrams included into delivery.
Each electric control will be delivered with corresponding circuit and wiring diagram!
Main current fuses must be provided on site.

Attention!
When using longer cables one must consider an additional loss of current.
Consult your electrical engineer.
The connecting cables are to be laid in suitable cable channels or protection tubes.
Sharp edges, wire edges, rough surfaces or screw threads which the cable wires may come in to con-
tact with, must be removed from around the cable channels.
Option CEE – Connector (assignment)
Pay attention to phase sequence and motor direction.

3.8 Overload protection:

Winches with a load of 1000kg and more have to be equipped with an overload protection.
The contactor control for winches with a capacity of 1000kg and more will include the electronic overload
protection. The overload protection operates by means of a load-monitoring device, which is adjusted to
100% up to 110% of the driving power. The mounted electronic overload protection works with a start
bridging and do not release the operator to check the carrying capacity and the charge.
Take care that the load does not interlock during the starting phase.
The overload protection does not operate by constant press-release in short intervals.
The electronic overload protection is a warning installation and it is not allowed for regular use to stop at
end positions. Use always path-dependent limit switches to stop at positions.
Take into consideration the rigidity of the complete lifting installation (inclusive frame etc.) in connection
with the max. overload time (start bridging, brake time, etc.) to determine the overload factor.
The max. overload should not exceed the upper limits of the carrying capacity of the system. (Take notice
of the valid directives.)
This overload protection system meets category 2 PL c analogue DIN EN 13849-1.
The functional safety must be checked regularly.
If the winch is integrated in a crane, the overload protection system for the complete system must be ana-
lysed by the manufacturer of the complete system and if necessary monitored by an additional load
measuring system.
The operator is not allowed to change the adjustment of the load monitoring device.
