● Cut sleeve (1) to match the shape of the mains cable.
● In the area marked 7 to 13 for round cable; in the area marked 18x7 to 20x8 for flat cable. The system is de‐
signed for cable cross-sections of 4x1,5 mm

.
● Slide sleeve (1) onto the mains cable. Make sure sleeve (1) tightly encloses the cable for the specified enclo‐
sure requirements.
● Connect the mains cable on connector (2) to terminals L1, L2, L3 and to the PE. If required, use the wire end
sleeves included in the delivery.
● Slide connector (2) into housing (3) until it latches and close housing (3) with sleeve (1).
● Then insert connector (2) into the control system until the housing (3) latches with the card bracket.
● Finally insert the mains cable into the opening in the gearbox housing and secure it with the strain relief clamp.
For DC-Com 1 to 5 units, the strain relief clamp must be turned to match the shape of the cable depending on
the cable type (flat or round cable).
● All housing parts must be securely latched to ensure the unit is sealed.
● Check continuity of the earth lead connection after the mains cable has been connected and before the chain
hoist is put into operation.
● The mains connector must never be disconnected under load.
Phase sequence for connection to the AC power network
The chain hoist is configured for connection to clockwise R-S-T phases. The lifting and lowering buttons corre‐
spond to the movements of the load hook if the R-S-T mains phases are connected to L1-L2-L3 in the specified
sequence. Then check the direction of movement as described below. If the phase sequence of the connection
cable is unknown, connection with the correct phases is established in this way.
Checking the direction of movement
The chain hoist must be connected to the power supply to check whether all phases are correctly connected.
Switch on the power supply, unlock the emergency stop and actuate the "Lifting" pushbutton on the control pend‐
ant. The load hook must now move upwards.
WARNING
Incorrect direction of movement
Danger to life and limb if the direction of movement is wrong.
–
If the direction of movement is not correct, disconnect the power supply at the mains connection switch and
check to ensure that it is not live.
– Swap phases L2 and L3 of the supply cable at the mains connection switch.
