Operation
In order to prevent repeated coupling and decoupling of the emergency
manual operation mechanism, the chain must be kept taut during operation.
The door can be opened and closed manually by pulling the respective side of the
chain vertically. In order to prevent electrical operation of the door system during
emergency manual operation, the safety switch S3F is activated when the chain is
pulled. After operation, ensure that the chain hangs "freely" again so that the safety
switch SF3 is released and electrical operation is enabled once more. It may be ne-
cessary to pull briefly on the chain in order to release the safety switch.
Voltage switching
Caution
Before voltage switching, the drive must be safely disconnected from the mains.
The drives can be operated on a 3~ 400 V (
-star connection) or 3~ 230 V (
-delta connection) network. The drives are delivered
pre-wired for operation on a 3~ 400 V network.

For operation on a 3~ 230 V network, the drive must be switched from
-star con-
nection to
-delta connection:
•
Remove the “3 x 230 V” sticker (1)
•
Switch the 6-phase motor plug (2) from
to
Electrical connection to the control unit and connection diagram
Caution
The electrical connection may only be carried out by a qualified electrician! Please ensure
adherence to all data on the supplied control unit and all applicable EN standards! When all
connection work is being carried out, the door system must be safely disconnected from
the mains by removing the plug/switching off the main switch. Observe the drive’s tech-
nical data. The limits given in the technical data must not be exceeded. In particular, the
on-site fuse protection of the door system, to be carried out by the customer, must comply
with the technical data!
When laying the protective conductor, it must be ensured that the protective conductor
connection (earth) is disconnected last if the cable is pulled out unintentionally, e.g., by
bundling the individual black wires of the connecting cable together to form a loop and fix-
ing this with a cable tie.
The individual wires must not be in contact with the gear wheels/cams of the limit switching
when the housing cover is closed.
Ensure that the connecting cable is routed in such a way that it is not in contact with the
drive.
