CAUTION
To ensure electrical safety:
‣
Do not disconnect the protective connection.
‣
Disconnect the supply voltage before disconnecting the protective earth.
Connect protective earth to the internal ground terminal (3) before connecting the supply
voltage. If necessary, connect the potential matching line to the external ground terminal.
In order to ensure electromagnetic compatibility (EMC): Do not only ground the device via the
protective earth conductor of the supply cable. Instead, the functional grounding must also be
connected to the process connection (flange or threaded connection) or to the external ground
terminal.
An easily accessible power switch must be installed in the proximity of the device. The power
switch must be marked as a disconnector for the device (IEC/EN61010).
