↻ The device has been installed on the mount.
1 Strip the insulation from the equipotential bonding cable.
2 Furnish the stripped cable with an M8 ring cable lug.
3 Lay the cable for equipotential bonding onto the grounding point and attach
with an additional M8 nut and lock washer [
4 Check that the connected cable is fitted securely.
» The housing is included in the equipotential bonding.

Connecting the interfaces
4.5.1 Overview
DANGER
Risk of fatal injury due to electric shock!
Severe injuries or death may result from improper use of the interface connections and failure to observe
protection class III.
›
The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with pro-
tection class III.
All interfaces are located on the communication circuit board (HMI board) inside the housing.

4.5.2 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.
