ATTENTION: Work at electrical installations may be carried out by el ectrical experts only. The local regulations have to be
strictly observed, e.g. EN 60204-32 / VDE 0113.
Preparation
Before beginning work on electrical components the mains current switch must be switched OFF and secured against unintentionally
being switched back on.
Before connecting the chain hoist ensure that the electrical data on the nameplate match the local supply specifications.
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.
• The circuit diagram is attached to the device.
Mains connection (3-phase device)
The mains supply cable must be an insulated cable with 4 flexible leads. The ground (earth) lead must be longer than the live leads. The
cross section should be at least 1.5 mm² and the cable length should be maximum 50 m. The fuses of the various models can be taken
from the tables.
Cable ends have to be provided with wire end sleeves.
The mains supply cable must be connected to the electric chain hoist before it is connected to the mains supply.
• In devices with an electric trolley (CPV/F-VTE/F), the three live phases of the mains supply line are to be connected to the terminal
strip within the terminal box of the trolley. The ground/earth wire is to be connected to the special ground/ earth connection within the
terminal box of the chain hoist.
• In devices without an electric trolley, the mains power supply is connected to the transformer behind the housing lid (Fig. 18, item 3).
The fork-shaped crimp cable lug of the ground cable is joined with a screw and a fan washer to the transformer plate.
Check the motor's direction of rotation.
The wiring diagram included has been drawn for a normal, clockwise rotating installation. Should the user's mains supply not fulfil this
standard, and if, after activating the circuit breaker or power supply line, a lowering takes place on pressing the

-button on the control
switch, deactivate the unit immediately and interchange two of the three phase connections in the control box.
Mains connection (1-phase device)
The mains supply cable must be an insulated cable with 3 flexible leads. The ground (earth) lead must be longer than the live leads. The
cross section should be at least 1.5 mm² and the cable length should be maximum 50 m. The fuses of the various models can be taken
from the tables.
Cable ends have to be provided with wire end sleeves.
The mains supply cable must be connected to the electric chain hoist before it is connected to the mains supply.
• In devices with an electric trolley (CPV/F-VTE/F), the N conductor, the phase and the ground wire are connected to the corresponding
terminal strips in the control box of the trolley.
• In devices without an electric trolley, the mains power supply is connected to the terminal strip of the hoist control plate.
ATTENTION: The settings of the time relay (ZR) should not be disturbed!
Open the housing only 3 minutes after disconnecting the device from the mains. There is risk of an electric shock from
undischarged capacitors.
After closing the terminal box cover, connect the other end of the connecting cable to the deactivated circuit breaker or to the mains
supply line.
Attention: Under no circumstances may the wiring in the pendant control be tampered with.
Adjustment of the gear limit switch (optional)
If the lifting unit to be installed is equipped with a gear limit switch, the switching points must be adjusted to the use situation without fail
before the start-up. After adjusting these switching points, the rope winch and the load as well as the operator can be protected against
damage or serious injuries.
This setting could not be defined by the manufacturer because of the unforeseeable number of possible use scenarios.
NOTE: Depending on the customer's request, gear limit switches with up to 6 other actuation cams can be delivered. The gear limit
switch translation is to be selected according to the switching space (distance between the highest and lowest switching point).
