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 Place the earth cable at the earthing point and secure it with an additional M8
nut and lock washer [W_17/ 88.5 In-Ibs ].
4 Check that the connected cable is fitted securely.

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.
CAUTION
Damage to the unit from electrostatic discharge
Components inside the unit can be damaged beyond repair by static discharge.
›
Note the ESD protective measures.
›
Earth yourself before touching a component by touching a grounded object.
All interfaces are located on the communication circuit board (HMI board) inside the housing.
