3. Mounting

3.1 General mounting instructions

Mounting: snaps onto standard DIN rails to EN 60715.
Snap the bottom of the enclosure slightly tilted forwards in the DIN rail
and push up until it latches in position.

33,6 V

3.2 Mounting of the sensors

The installation of the intrinsically safe current circuits must be executed
in accordance with the applicable standards IEC/EN 60079-14 (ABTN
NBR IEC 60079-14.
According to IEC/EN 60079-11 (ABTN NBR IEC 60079-11),
the following must be observed for the installation: a distance
of ≥ 6 mm must be observed between the terminals of the
intrinsically safe current circuits and other intrinsically safe
current circuits. Between the terminals of the intrinsically
safe current circuits and other, non-intrinsically safe current
circuits, a distance of ≥ 50 mm must be observed.
The commissioning and installation are to be executed by
qualified professionals only.

3.3 Installation in Zone 2: particular conditions

The devices must be installed in control or junction boxes, which meet
the requirements to IEC/EN 60079-15 (ABTN NBR IEC 60079-15) and
have at least protection class IP54 (Fig. 1). To respect temperature
class T5, the device must have a free volume of at least 2,400 cm³.
Please make sure that you have read and understood these operating
instructions and that you know all applicable legislations regarding
occupational safety and accident prevention prior to installation and
putting the component into operation.
The intrinsically safe current circuits of the device (light blue terminals)
may be lead in explosion-endangered areas. In this case, it must be
especially observed that they are safely separated from all non-intrinsi-
up to e
cally safe current circuits.
up to 4
The connection and separation of the connections of
non-intrinsically safe current circuits is not authorised

/h
in explosion-endangered atmospheres.
up to 3
Only use a damp cloth to clean the enclosure.
The lifetime of the safety-monitoring related to
the ignition protection class "nC" is at least 15 years.
Upon expiration of this time, the safety-monitoring modu-
le must be replaced either returned to the manufacturer
for check-up!
The temperature specifications (–25 °C ≤ Ta ≤ +60 °C) of
the safety-monitoring module are related to a volume of the
control cabinet of at least approx. 2,400 cm³ for each SRB.
The distance with regard to other safety-monitoring module
imperatively must be at least approx. 5 cm.
