3 Installation

uProtect device and cable against destruction.

uAvoid electrostatic charging on plastic housings and cables.

uTo avoid electrostatic charging, ensure the equalisation of potential of metal parts (connector

housing, fixing elements, protective housing, etc.).

uDo not install the device in the partition between different zones.

uWhen used in zone 0, protect the sockets against intensive electrostatic charging.

3.1 Special conditions for safe operation

uAlways refer to the operating instructions for the identification, as it may not be fully applied to the

device due to lack of space.

4 Maintenance, repair and disposal

The device must not be modified nor can it be repaired. In case of a fault please contact the

manufacturer.

If needed, data sheets and type examination certificates or other certificates can be requested from

the manufacturer (Ò cover sheet / back).
