EXPLOSION
HAZARD!
Operation of devices without explosion protection in potentially explosive areas.
The operation of components without the appropriate explosion protection in potentially
explosive areas can lead to explosions.
5.1 Safety pointers for the electrical connection
DANGER!
Connecting the service voltage.
Improper connection of the service voltage can be potentially fatal. The instrument may also
be damaged. Local regulations for electrical connection must be observed at all times.
Further, the following basic principles must be observed:

Consult the documentation for the Ex-P system before carrying out the electrical installa-
tion.

Because the instrument has no main switch, a suitable disconnection device (switch,
plug) should be installed near the service voltage. It must be designated and easily ac-
cessible.

It is imperative that the protective conductor is connected.

The instrument must not be charged with voltage until the installation is completed and
the door is closed.

A back-up fuse with a max. tripping current of 16 A must be present. The cables must
be able to withstand this load.

If faults cannot be remedied, the unit must be put out of operation and protected
against inadvertent operation.
