Installation Of Electrical Equipment In Explosion Risk Areas - Kessel SonicControl Anleitung Für Einbau, Bedienung Und Wartung

4.5 Installation of electrical equipment in explosion risk areas

The self protected electrical systems of the SonicControl, which are
identified by their blue color, are certified for installation in explosion
risk areas and to be used with the Ex i-connections of the SonicControl
ATEX.
The electrical installation in explosion risk areas must follow EN 60079-
0 and EN 60079-14 regulations.
Installations in Germany must also follow EIN 60079-14VDE 0165 Part
1 regulations.
4. Electrical Connections
When connecting the intrinsically secured circuit of the associated
equipment - installation in a secure area- (SonicControl ATEX control
unit) and when connecting of the intrinsically secured equipment - in-
stallation in explosion rated area - (SonicControl ATEX sensor), be
sure that all related max values (U; I; P) are followed and met.
Since the interconnection of the two explosion-protected resources
was certified through the EC type approval certificate (EGB) BVS 11
ATEX E 040 X, no proof of intrinsic safety must be brought in compli-
ance with guideline 94/9/EC up to 19.4.2016 and from 20.4.2016 in
compliance with guideline 2014/34/EU.
