Installation instructions

ATEX/IECEx

The installation, commissioning, maintenance and repair of
devices in potentially explosive atmospheres must only be
carried out by appropriately trained personnel.
The safety instructions for the correct use of electrical
apparatus in potentially explosive atmospheres must be
observed, in accordance with Directive 2014/34/EC (ATEX) and
IEC 60079-14 (Installation of electrical equipment in potentially
explosive atmospheres).
The requirements set out in EU Directive 1999/92/EC (minimum
requirements for improving the safety and health protection of
workers potentially at risk from explosive atmospheres) must
be fulfilled to ensure safe operation.

Use in areas exposed to combustible dust

When using the device in areas exposed to combustible dusts
(dust ignition), the following points must be observed:
• The maximum surface temperature of the device may not
up-scale the following values.
FEP631, FEH631 80 °C (176 °F)
FEP632, FEH632 80 °C (176 °F)
FET632 80 °C (176 °F)
• The process temperature of the attached piping may up-
scale 80 °C (176 °F).
• Approved dust-proof cable glands must be used when
operating in Zone 21, 22 or in Class II, Class III.
• In potentially explosive atmospheres, the signal cable must
measure at least 5 m (16.40 ft).

Cable entry

The devices are supplied with cable glands installed (certified
in accordance with ATEX or IECEx).
The use of standard cable glands and seals is prohibited.
The black plugs in the cable fittings are intended to provide
protection during transport.
The outside diameter of the connection cable must measure
between 6 mm (0.24 in) and 12 mm (0.47 in) to guarantee the
required tightness.
Black cable fittings are installed by default when the device is
supplied. If signal outputs are connected to intrinsically safe
circuits, replace the black cap on the corresponding cable gland
with the blue one supplied.
Any unused cable entries must be sealed before commissioning
in accordance with the applicable standards.
Note
Low-temperature version devices (optional, up to −40 °C
(−40 °F) ambient temperature) are supplied with metal cable
glands due to the required temperature resistance.
Note
Devices which are certified for use in North America are
supplied with a ½ in NPT thread only and without cable glands
or sealing plugs.
