For cULus applications, the S5B resin housing is
only intended for use with flexible conduit.
In addition to IO&M Manual instructions, it is
required to follow all instructions specified in
Control Drawing: WD-000393.
S5A and S5B I.S. VSMs must be used in
conjunction with a third party approved
barrier that meets conditions specified in
the control drawing: WD-000393.
Enclosure may contain aluminum. Care must be
taken to avoid hazard due to impact or friction
Resin housings pose an electrostatic charging
hazard. See Control Drawing: WD-000393
Substitution of components may impair intrinsic
safety.
NOTICE
The Bray Series 5A and 5B I.S. VSMs are compliant
to the IEC/EN 60079-11 section 6.3.13 dielectric
strength requirement.
8. Pre-Installation Storage
Bray Series 5A and 5B I.S. VSMs are not weatherproof
until properly installed on the quarter-turn device
or prepared for storage. Bray cannot accept
responsibility for deterioration caused on-site once
the cover is removed.
NOTICE
Units are shipped with two screw-in plugs
(aluminum housing) or peel-off decal (resin
housing) to prevent foreign matter from
entering the unit through the conduit openings.
To prevent condensation from forming inside
these units, maintain a near constant external
temperature and store in a well-ventilated, clean,
dry room away from vibration.
Store units on a shelf or wooden pallet in order
to protect against dampness.
Keep units covered to protect against dust and
dirt.
Storage Temperature should be maintained
between -25°C and 65°C.
