Special Conditions :-
1. The pressure transmitter may be fitted with an integral display or alternatively, when the blanking
plate is removed, a hand held display may be inserted into the socket provided. The removal of the
blanking cover is only permitted in a non-hazardous area.
2. The pressure transmitters intended for operation at 50 V dc do not meet the requirements of EN
50020:2002 clause 6.4.12 (Electrical Strength Test). This shall be taken into account when
installing the apparatus in a potentially explosive atmosphere.
SYSTEM
The user/installer is responsible for ensuring the safety parameters of the circuit/system are not
exceeded. Refer to IEC 60079 -14: Electrical apparatus for explosive gas atmospheres - Electrical
installations in hazardous areas (other than mines) and EN 60079 –25: Electrical apparatus for
explosive gas atmospheres - intrinsically safe systems
