Installation

The installation, commissioning, maintenance and repair of
devices in areas with explosion hazard must only be carried
out by appropriately trained personnel.
The operator must strictly observe the applicable national
regulations with regard to installation, function tests, repairs,
and maintenance of electrical devices. (e.g. NEC, CEC).
NOTICE
Observe the device's applicable specifications and special
conditions in accordance with the relevant certificate.
— Any manipulation of the device by users is not permitted.
Only the manufacturer or an explosion protection
specialist may modify the device
— The device may only be operated with instrument air that
is free of oil, water, and dust.
3.3.1

Cable gland

Limited temperature range of the M20 x 1.5 plastic cable
gland for explosion protection variants.
The permissible ambient temperature range of the cable gland
is -20 ... 80 °C (-4 ... 176 °F). When using the cable gland,
make sure that the ambient temperature is within this range.
The cable gland must be installed in the housing with a
tightening torque of 3.8 Nm. When installing the connection of
the cable gland and cable, check for tightness to ensure that
the required IP rating is met.
3.3.2

Operation with flammable gas

Observe the following points when operating a device with
flammable gases:
— The device must be used in accordance with the
specifications in the relevant certificate.
— Only the design with the IS "Intrinsic Safety " type of
protection may be operated with natural gas. The
pneumatic outputs must be vented in non-hazardous
areas.
— During operation with flammable gases, the cover cap for
the air outlets must be removed, and the air outlets can be
tubed separately. Both pipes may not be joined in one
pipe.
— The maximum ambient temperature must not exceed
60 °C (140 °F).
