Making the Ethernet connection
NOTE
The connection plug of an RJ45 cable is larger than the opening of an M25 cable fitting when it is installed.
For this reason, remove the sealing insert before installation and thread the Ethernet cable outside of the
cable fitting through the sealing insert.
NOTE
Use a suitable category 7 network cable. The maximum distance between two devices is 100 m (328 ft). The
Ethernet switch allows for the repeater function and supports auto-sensing. Ensure that the cable is cor-
rectly assigned. You can use both crossed and 1:1 protectively-wired Ethernet connection cables.
↻ Connecting cable inside the device.
1 Plug in an Ethernet cable at one of the two Ethernet ports on the communication circuit board.
2 Check that the connecting cable is fitted securely.
» Connect additional signal cables.

Sealing the connection area
↻ Grid connection is prepared.
1 Lift the housing cover onto the housing and loosely tighten the fastening
screws.
2 Secure the housing cover (1) by tightening all 14 screws (2) in a diagonally op-
posite sequence [
