amb
= –50 to 60 °C)
1180
SPECIAL CONDITIONS FOR SAFE USE (X):
1. This apparatus must be installed in an enclosure which affords it a degree of protection
of at least IP20. Non-metallic enclosures must have a surface resistance of less than 1
Gohm. Light alloy or zirconium enclosures must be protected from impact and friction
when installed.
2. The apparatus will not meet the 500V rms isolation test required by Clause 6.4.12 on
EN 60079-11:2007. This must be taken into account when installing the apparatus.
