Repair of this equipment shall be carried out by suitably trained personnel in accordance with
the applicable code of practice such as EN 60079-19
The certification of this equipment relies upon the following materials used in its construction:
o
Enclosure
– 316L Stainless Steel or Aluminum
o
Window
– Sapphire Glass
If the equipment is likely to come into contact with aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection provided by the equipment is not
compromised:
o
Aggressive substances: acidic liquids or gases that may attack metals, or solvents

Installation Cables
Follow the following guideline for the cable installation:
All cables to the detector must be well shielded in order to comply with EMC requirement
(see Technical Specifications in
Ground the detector to the nearest ground point (not more than 3m from the detector
location)
Install the detector with the cable entries placed downwards
2.5.1 Conduit Installation
The conduit used for the cabling must comply with the following:
To avoid water condensation in the detector
– install the detector with the conduits placed
downward (for those that include drain holes)
When using the optional tilt mount, use flexible conduits for the last portion connecting to the
detector
For installations in atmospheres as defined in group B of the NFPA 72E, seal the conduits
inlets
When pulling the cables through the conduits
– ensure that cables are not tangled or
stressed
NOTE: Extend the cables about 30 cm. (12 in.) beyond the detector location to accommodate
wiring after installation.
After the conductor cables have been pulled through the conduits, perform a continuity test
