4.7.2 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 5 network cable. The maximum length of a network segment is 100 m. Ensure that
the cable is correctly assigned. The Ethernet connection of the device supports auto-sensing. 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 Loosely fasten the connection cable to the door beams using cable ties.
3 For shielding, strip the Ethernet data cable at the position of the shield clamp up to the wire mesh (approx. 20mm)
and fix it with cable ties.
4 Check that the connecting cable is fitted securely.
5 Tighten the cable fittings [[ W_29 / 4 Nm].
» Connect additional signal cables.
4.8 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 by tightening the 4 screws in a diagonally opposite se-
quence [ T_30
/
10 Nm].
»
The device has been mounted and installed.
» Put the device into operation.
