= –50 to 60 °C)
Special Conditions of Safe Use (x):
1. The apparatus must be installed in an enclosure that provides a
degree of protection of at least IP20. Non-metallic enclosures must be
suitable to prevent electrostatic hazards and light alloy or zirconium
enclosures must be protected from impact and friction when installed.
2. The apparatus is not capable of withstanding the 500V isolation test
required by IEC 60079-11: 2006 clause 6.3.12. This must be taken
into account when installing the apparatus.
