Information
Cable laying
For all versions, care must be taken that the cables and the cable glands at least comply with the protection class
of the device and the attachment regulations and are carefully matched. The cables must be inserted so that
water is deflected away from the device (if necessary use loops). This is essential to ensure that the required
protection class is maintained.
IP55 version:
The IP55 version is the standard version. In this version, the two installation types motor mounted
(fitted onto the motor) and close coupled (fitted to the wall bracket) are available. All adapter units,

design modules.
