Mains Supply Connection
• The mains supply cable must be an insulated cable with 4 flexible leads. The ground (earth) lead must be longer than the live leads.
Cable ends have to be provided with end sleeves.
• Please observe the following table without fail for minimum cross-sections of the power supply cable!
Connection to the mains power supply is established in accordance with the wiring diagram on the cover of the terminal box, or
displayed in the operating instructions manual.
ATTENTION: The electric rope winch must be cabled fully before the cable is connected to the circuit breaker or the mains
power supply.
Control switch connection
• The length of the pendant control cable is determined by working conditions. Attach the tension relief wire in a manner that the
pendant control cable hangs load-free. Cable ends have to be provided with end sleeves.
• Always use tension releasing cable sleeve, if the suspended cable is longer than 30 m!
Check the motor's direction of rotation
The enclosed circuit diagram is drawn according to the current standard for a clockwise rotating field. If the operator's mains does not
comply with this standard and if, after switching on the isolating switch or the power supply, the control pendant moves in the opposite
direction to that in which it is wound up by pressing the
▲
key, switch off the unit immediately, disconnect it from the mains supply and
swap two of the three phase connections in the switch box.
Attention: Under no circumstances may the wiring in the pendant control be tampered with.
Wire rope installation
Attention: Always wear protection gloves for handling wire ropes.
• Only ropes have a minimum strength of 1770 N/mm² with shielding and in accordance with EN 12385-1 are to be used. A low spin
rope must be used if the load can break free.
• Make sure that the wire rope has the correct diameter and an adequate length.
Measure the rope length in such a way that at least 2 1/2 turns remain on the drum.
• Always uncoil the wire rope properly and without a spin (caused by the rotation with reel) Otherwise, the wire rope could get entangled
while being coiled/uncoiled on the drum and become unusable.
• Examine the condition of the wire rope:
- Cable eye/pressure grouting not damaged?
- For ropes with hooks: the fuse hatch is intact, hooks are not bent?
- Proper rope tip without visible damage along the entire length?
To mount the wire rope, insert the hook-less end into the provided hole in the drum and push such that the rope end does not protrude
any more from the other end of the hole Observe the direction of rotation of the drums. The wire rope end must be introduced into the
mounting hole in such a way that it is not damaged by the chamfering of the hole during the winding on the drum. Eventually, both
provided copper washers are to be placed in the screw holes to prevent the wire rope being damaged during the subsequent stretching.
The two mounting screws are to be screwed into the appropriate threaded holes and tightened with the tightening torque specified in the
table.
NOTE: If the present rope winch is equipped with an optional rope guide, before fastening a wire rope it must be fully pushed to the
drum side on which the rope fastening hole is located, so that the free rope end must be inserted through the rope guide plate only
before it can be threaded in the rope fastening hole.
ATTENTION: A rope guide unit should only be used together with a grooved rope drum. In case of an installed rope guide,
more wire rope should not be wound on the drum under any circumstances than the lowest position of the rope drum can
hold. The holding capacity of the rope drum in the lowest position and not the wire rope length restricts the maximum lifting
distance.
