Electrical Installation (FM Sensors)
The Series 200 Sensor is approved, as an entity, as
Intrinsically Safe when installed in conformance with Bad-
ger Meter installation drawings 06-480-001 or 06-480-002
(samples shown on Page 7) as specified on the blue label
identifying an intrinsically safe sensor.
Entity approval implies that only the sensor is approved
as intrinsically safe. Unless power supplies, equipment,
and instruments connected to the sensor are each rated
either explosion-proof or intrinsically safe, these devices
cannot be installed in a hazardous area. The referenced
installation drawing shows such apparatus located in
a non-hazardous location. Proper interfacing between
the hazardous and non-hazardous areas must be pro-
vided. It is of absolute importance that this interface be
constructed and that all wiring be performed by qualified
contractors. To ensure the Intrinsic Safety of the instal-
lation, the connection of the intrinsically safe sensor to
instruments and or power supplies must take place using
an approved intrinsically safe barrier located in a non-
hazardous area. These barriers, listed below, are readily
available from various suppliers.
