Section 2. Mounting the Gas Detector
2.1. Warnings and Prerequisites
WARNING:
Explosion hazard! Do not mount the MGS-250 in
an area that may contain flammable liquids, vapors, or
aerosols. Operation of any electrical equipment in such an
environment constitutes a safety hazard.
CAUTION:
The MGS-250 contains sensitive electronic
components that can be easily damaged. Do not touch or
disturb any of these components.
NOTE:
The mounting location of the monitor should allow it to
be easily accessible for visual monitoring and servicing.
NOTE:
The monitor must be connected to a marked, suitably
located and easily reached switch or circuit-breaker as means
of disconnection.
NOTE:
Connect monitor power and signaling terminals using
wiring that complies with local electrical codes or regulations for
the intended application.
CAUTION:
Do NOT mount the MGS-250 directly to vibrating
machinery as the vibrations may degrade the gas detector’s
performance.
2.2. Mounting Locations
2.2.1. General Placement Guidelines
NOTE:
The MGS-250 should be installed plumb and level
and securely fastened to a rigid mounting surface.
NOTE:
When installed in areas that may be subjected to
water spray, the optional splash guard (P/N: 6900-0001)
should be used in conjunction with the MGS-250.
Gas detectors must be located within the appropriate wire lengths from
the central control unit (if used).
