Functions
Galvanically isolated connection of measuring
two wire transducers by meaning of standard
analog signals 0/4...20 mA from hazardous
area into safe area.
Special conditions for application in zone 2
For installation in zone 2 the device must be
installed in a housing which complies with the
requirements of EN 60079-15 with a minimum
protection degree of IP54 according to
IEC/EN 60529.
With mounting in zone 2 the connecting and
disconnecting of energized non energy limited
circuits is only permitted in non-explosive
atmosphere.
The application of litz-wires recommends the
fi xation of cable ends with wire sleeves.

Mounting and Installation (Fig. 4 + 5)
The device is suited for snap-on clamps for
DIN rail mounting (EN 60715).
Devices of the same type may be mounted
directly next to each other. It must be ensured
that heat is conducted away from the device.
Mounting and installation must be carried out in
accordance with the applicable regulations.
The operator is responsible for compliance with
the regulations.
The device must be protected against dust,
dirt, moisture and other environmental infl u-
ences as well as against strong electromagnetic
emissions.
It should also be protected against the risks of
mechanical damaging, unauthorized access
and incidental contact.
All installations must be carried out observing
the regulations of EMC protection.
The cable junction via cage-clamp terminals is
shown in Fig. 4.
