The equipment must be installed in an enclosure which affords it a degree of protection
of at least IP20 in accordance with the requirements of IEC 60529. Non-metallic
enclosures must have a surface resistance of less than 1GΩ; light alloy or zirconium
enclosures must be protected from impact and friction when installed in a Zone 0
environment.
When fitted with the Transient Protector Assembly, the equipment is not capable of
withstanding the 500V test as defined in Clause 6.3.13 of EN 60079-11:2012. This must
be taken into account during installation.
