WARNING
All installation and maintenance must be carried out by a suitably skilled electrician
in accordance with all local and national standards and codes of practice e.g. NFPA70
(National Electrical Code), CSA C22.1 (Canadian Electrical Code, Part I Safety Standard for
Electrical Installations), IEC/EN 60079-14 (Explosive atmospheres - Electrical installations
design, selection and erection) and IEC/EN 60079-17 (Explosive atmospheres. Electrical
installations inspection and maintenance).
•
The installer must comply with the technical data attached.
•
Ensure that all items are approved and certified for the environmental and installation
requirements. The rating label must be checked to ensure the unit is being used within
the correct ambient temperature and environmental conditions, and that the power
supply is suitable.
•
Use stainless tools to avoid rust stains or pitting corrosion. Stainless steel is
corrosion-resistant, but extraneous rust can appear if the material is handled incorrectly.
•
Equipment must be installed ≤2 000 m above sea level.
•
Modifications or design changes to the devices are not allowed.
•
Safety rules and national regulations must be observed.
•
Never install devices in areas that may exceed the ambient temperature range.
•
Aggressive substances may require extra protection.
•
The device must be protected by additional means of protection if it is exposed to
excessive external stress, that is vibration, heat or impact.
•
If the device is not utilized in a manner specified by the manufacturer, the device's
protection may be impaired. Incoming cables must comply with the national standards.
Suitably certified cable glands and blanking plugs must be used. Thread form must be
M25x1.5 or M20x1.5, depending on product type, with tolerance 6g/6H according to
ISO 965. The cable gland used must not invalidate the IP rating of the enclosure and
must be rated for the installation.
•
Devices of type P21 must use CMP type PXSS2K cable glands. We recommend using the
following cable glands:
-
Ex d Cable Gland M20 armored cable
-
Ex d Cable Gland M20 non-armored cable
•
All entries must be plugged with suitable certified equipment.
•
Fixing brackets must be tightened upon installation. Suitable screws must be used. See
the product's datasheet for information about the product weight.
•
Replacement parts may only be installed using component parts as specified by Axis
Ex AB.
•
Distances between the flamepaths and sunshield and between the flamepaths and any
other obstruction (such as a wall or a ceiling) have been considered in the ATEX/IECEx
