Electrical Connections

Incoming power and signal output connections are made to a terminal block mounted on a PCB

located in the explosion proof enclosure.

Do not supply voltage more than specified in this

manual and noted near the power input terminal of the

analyzer.

The PCB in the explosion proof enclosure contains a

power limiting intrinsic safety barrier that limit the total

power available at the PCB electronics mounted in the

general purpose enclosure.

With proper insulation of the incoming power (see

Appendix A), this configuration of the GPR-1800 IS

conforms to the ATEX directives for equipments for use

in hazardous area. The analyzer meets the following

area classification:

II 2 G

Ex d [ib} ib IIB T4

amb

-20⁰C to +50⁰C

Ex enclosure for power input

The GPR-1800 IS also meets the intrinsic safety standards required for use in Class 1, Division 1, Group C,

D hazardous areas.

The A-1166 IS PCB in the Ex enclosure contains two fuses, one plug-in (brown color) rated at 50 mA and

the second mounted on the PCB (meets barrier network standard EN 50020).

Avoid electrostatic discharge – Clean all surfaces with a damp cloth only.

Analyzer ground terminal must be
