Creating equipotential bonding

NOTE
Depending on the local installation specifications, it may be necessary to earth the device with a second
ground connection. To this end, the threaded bolt on the underside of the device can be used.
↻ 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 [ W_17/
4 Lay the cable for equipotential bonding onto the grounding point and attach
with an additional M8 nut and lock washer [ W_17/
5 Check that the connected cable is fitted securely.
» The housing is included in the equipotential bonding.

Connecting the interfaces

7.9.1 Overview
DANGER
Risk of fatal injury due to electric shock!
Severe injury 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 device from electrostatic discharge
Components inside the device can be damaged beyond repair by static discharge.
› Note the ESD protective measures.
› Earth yourself before touching a component by touching a grounded object.
NOTE
Due to the installation position of the communication circuit board, this must be specially safeguarded
against moisture and exposure to dust.
› Make sure that no moisture or dust impacts on the circuit board during installation. Moisture and dust
particles must be removed immediately. In doing so, disassembly of the circuit board may be neces-
sary.
All interfaces are located on the communication circuit board on the inside of the housing door.
