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 M4 ring cable lug.
3. Lay the equipotential bonding cable onto the grounding point and attach with
the M4 x 10 bolt and lock washer provided [ W_T30/
4. Check that the connected cable is fitted securely.
ð The housing is included in the equipotential bonding.

Connecting the interfaces

7.6.1 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 pro-
tection class III.
1. The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with protec-
tion class III.
CAUTION
Damage to the device from electrostatic discharge
Components inside the device can be damaged beyond repair by static discharge.
1. Observe the ESD protective measures.
2. 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.
