4.3 Explosion Protection

The junction box is simple electrical equipment in accordance with EN 60079-14
or EN 50020. It may be used in hazardous areas also for connecting intrinsically
safe circuits.
The terminals meet the requirement for separating intrinsically safe circuits – creep
and air gap > 6 mm.
WARNING
To be observed when using in hazardous areas:
The regulations governing the installation and operation of devices in
-
explosive areas that are in force in the country of use.
In EU countries, the laws passed in the relevant country to enforce EU
-
Directive 1999/92/EC
The regulations for erecting electrical installations in areas with a risk of
-
explosion DIN EN 60079-14 (VDE0165) or DIN EN1127-1.
EC Type Examination Certificate
-
All work on electrical circuits for systems where there is a risk of explosion must
be performed by qualified personnel.
