6. Mounting and Installation
Ex components are not intended to be used alone. Mounting and usage of
Ex components in devices or systems must be certified separately.
Ex components have the U marking at the end of the certificate number.
Observe the instruction manuals for the associated components.
Observe the installation instructions according to IEC/EN 60079-14.
Observe directives, standards, and national laws applicable to the
intended use and the operating location.
Examples for such regulations are regulations regarding electricity,
grounding, installation as well as hygiene and safety.
If you intend to install the device or enclosure in areas
that may be exposed to aggressive substances, ensure that the stated
surface materials are compatible with these substances. If required,
contact Pepperl+Fuchs for further information.
Ensure that the device provides and maintains a degree of protection
of at least IP66 according to IEC/EN 60079-0.
Observe the requirements
according to IEC/EN 60079-31regarding excessive dust deposits.
In order to guarantee the temperature class, ensure that adequate
free air exists around the enclosure.
The product certification allows smaller distances than the specified
distances according to IEC/EN 60079-14:
Gas group IIA: = 10 mm
l
Gas group IIB: = 10 mm
l
Gas group IIB+H : = 10 mm

The enclosure cover is heavy. In order to avoid personal injuries or
property damage, make appropriate provisions for the mounting
procedure.
Do not damage the flamepath surfaces between enclosure and enclosure
cover during the opening of the control panel.
If one of the flamepath surfaces is damaged, exchange enclosure and
enclosure cover.
Before fixing the enclosure cover to the enclosure, protect the flamepath
surfaces with a thin layer of suitable protective grease.
When the cover is fitted, ensure that all fasteners are fully tightened.
Tighten all screws of the enclosure/enclosure cover with the appropriate
torque.
Ensure that there are no external heat sources around the enclosure.
Safety-relevant markings are found on the nameplate supplied.
Ensure that the nameplate is present and legible. Take the ambient
conditions into account.
Additional warning markings may be on separate labels
besides the nameplate.
Ensure that the enclosure is not damaged, distorted, or corroded.
Ensure that all seals are clean, undamaged, and correctly fitted.
Close all unused enclosure holes with the appropriate stopping plugs.
Only use stopping plugs that are suitably certified for the application.
If mounting the enclosure on concrete use expansion anchors.
When mounting the enclosure to a steel framework use vibration resistant
mounting material.
If external connections exist, ensure that the connections
are in good condition, and are not damaged or corroded.
In order to prevent condensation in the enclosure, use suitably certified
breather drains.
6.1. Requirements for Cable Glands
Only use cable glands that are suitably certified for the application.
Only use cable glands with a temperature range appropriate to the
application.
For cable glands only use incoming cable diameters
of the appropriate size.
For control panels with IECEx certification, only use cable glands with
metric thread or NPT thread.
Use seals that are suitable for the specified application.
Ensure that the degree of protection is not violated by the cable glands.
Install cables and cable glands in a way that they are not exposed to
mechanical hazards.
The cables and connection lines must be free from mechanical stress.
Use appropriate strain relief, which must be fitted outside of the enclosure.
Ensure that all cable glands are in good condition and are securely
tightened.
Close all unused cable glands with the appropriate sealing plugs.
Observe the specific ambient conditions of sealing plugs.
Tighten all cable glands with the appropriate torque.
Ground metal cable glands.
7. Operation, Maintenance, Repair
Observe the requirements according to IEC/EN 60079-14
during operation.
Observe IEC/EN 60079-17 for maintenance and inspection.
Observe the requirements according to IEC/EN 60079-19 for repair
and overhaul.
Check the wear on the device and the device components at specific
intervals. The interval between checks depends on the operating
conditions and loads that occur.
