1.3
Mechanical installation
– Strict compliance must be given to the local, state, national
codes and regulations that govern the installation of gas
monitoring equipment.
– The future use of accessories and maintenance
equipment must be kept in mind.
– The instrument must not be exposed to radiant heat that
will cause the temperature to rise beyond the limits stated
in 15.5 Environmental parameters. The use of a reflecting
shield is recommended.
– The instrument may be equipped with a dust plug at the
conduit entry. This plug is not explosion proof nor meant to
be watertight, and must be removed before connecting the
instrument to a sealed conduit or installation of a
flameproof cable gland.
– Unused openings must be closed with a plug. For correct
tightening torques of conduit hubs, cable glands, plugs
and sensor see 15.6 Tightening torque.
– For non-conduit installations, an approved cable gland
must be used (e.g. Hawke A501/421/A/¾" NPT or
equivalent)
– WARNING: Only for conduit installations: To reduce the
risk of Ignition of Hazardous Atmospheres, the conduit
must be sealed within 45 cm (18") of the enclosure.
1.4
Electrical installation
– Strict compliance must be given to the electrical codes
that govern the routing and connection of electrical power
and signal cables to gas monitoring equipment.
– The instrument must have between 10 to 30 VDC at the
instrument.
– Ferrules must be used.
