DEMAG DC-Com 1 Operating Instructions Manual page 49

● For a round cable in the marking area of 7 to 13, for a flat cable in the marking area of 18 x 7 to 20 x 8. Cable
cross-sections 4x1,5 mm
● Slide the sleeve (1) onto the mains cable. Make sure the sleeve (1) tightly encloses the cable to comply with the
type of enclosure.
● Connect the mains cable on the connector (2) to terminals L1, L2, L3 and to the PE. If required, use the wire end
sleeves included in the delivery.
● Slide the connector (2) into the enclosure (3) until it latches and close the enclosure (3) with the sleeve (1).
● Then place the connector (2) into the control system until the enclosure (3) latches with the board bracket.
● Finally, insert the mains cable into the union on the gearbox housing and fix it with the strain relief clamp. For DC-
Com1 to 5 units, the strain relief clamp must be turned to suit the cable contour depending on the cable type (flat
or round cable).
● All enclosure parts must be securely latched to ensure the unit is sealed.
● After connection of the mains cable and before putting the chain hoist into operation, check the continuity of the
earth lead connection.
● 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 an R-S-T network turning clockwise. For connection of the mains
phases R-S-T to L1-L2-L3 in the specified sequence, the lifting and lowering buttons correspond to the movements
of the load hook. Then check the movement directions as described in the following. If the phase sequence of the
connection cable is unknown, this is the way to establish the connection with the correct phases.
Checking the direction of movement
To check whether all phases are correctly connected, the chain hoist must be switched. Switch on the power supply,
unlock the emergency stop and actuate the "Lifting" pushbutton on the control pendant. The load hook must now
move upwards.
WARNING
Incorrect direction of movement
There is a danger to life and limb due to an incorrect direction of movement.
– If the direction of movement is incorrect, switch off the power supply on the mains connection switch and
check that the unit is deenergized.
– Change over leads L2 and L3 of the supply cable on the mains connection switch.
or 4x2,5 mm are taken into account.
