Ethernet CPU module and
power module for Zone 1/Class I, Div.1
Series 9441, Series 9444, Series 9492
Ignition sparks
Ignition sparks can be generated during live working, when working with screws or
routing connections on a device that has not been fitted according to regulations.
This may result in explosions causing serious or even fatal injuries to persons in the vicinity.
Carry out all screw fastening processes carefully using the respectively specified
tightening torques.
Sufficiently secure communication lines against tensile force
(e.g. by tightening the strain relief cap, cable ties, screws).
Special approval is needed to connect or disconnect the unconnected cable end of the
socket in Zone 1 when live.
Improper project engineering, mounting, installation, commissioning, maintenance or
cleaning
Basic work such as installation, commissioning, maintenance or cleaning of the device must
be performed only in accordance with the valid national regulations of the country of use and
only by qualified persons. Otherwise the explosion protection can be rendered ineffective.
This may result in explosions causing serious or even fatal injuries to persons in the vicinity.
Have the mounting, installation, commissioning and maintenance work performed by
qualified and authorised persons only (see Chapter 3.2).
Observe the correct mounting position; see the "Mounting and installation" chapter.
Do not change or modify the device.
For use in Zone 1 and Zone 2, install the device in a protective enclosure or cabinet that
corresponds to a recognised type of protection in accordance with IEC/EN 60079-0 and
a degree of protection of at least IP54 in accordance with IEC/EN 60529.
For use in a safe area, install the device in an environment according to IEC/EN 60664-1
with a degree of pollution of 1 or 2 and an overvoltage category of I, II or III
(e.g. enclosure, cabinet).
Lay intrinsically safe and non-intrinsically safe electrical circuits in accordance with the
national installation regulations, such as IEC 60079-14.
Ensure that there is a distance of at least 50 mm (tight string length) between connecting
units of intrinsically safe and non-intrinsically safe electrical circuits.
For use in dust hazardous areas, before opening the enclosure, ensure that no explosive
dust-air mixture is present.
Connect the DIN rail on the BusRail to the potential equalisation in the hazardous area
during operation in hazardous areas.
Only connect the free unconnected cable ends in a suitable, certified connection chamber.
Maintain a distance of at least 20 mm between the CPU module, power module and
enclosure so that the air circulation is not restricted.
Repair work on the device must be performed only by R. STAHL.
Gently clean the device with a damp cloth only and without scratching, abrasive or
aggressive cleaning agents or solutions.
