Clear Lockable Water-proof Lens Cover OP-N4X/96X48
Metal Surround Case Option OP-MTL96X48
The clear lockable cover is designed to be dust
and water proof to NEMA-4X, IP65 standards. The
assembly consists of a base and cover with a cam
hinge and key-lock fastening mechanism. An O-ring,
or neoprene gasket forms a seal between the base
and the panel. The cam hinge prevents the cover from
closing when opened until pushed closed. The cover
has a tapered recess that, when closed, forms a seal
with a tapered spigot on the base. A key-lock employs
a cam locking device to force the spigot into the
recess, ensuring seal integrity. A safety catch keeps
the cover closed even when the key is removed, and
the keyhole can be used to attach a safety seal clip,
preventing unauthorized opening.
The meter’s plastic case is made from fire retardant polycar-
bonate. A metal surround case can be ordered to enhance the
meter’s fire retardant capabilities and also provide shielding
against electromagnetic interference (EMI). The metal case
slides over the polycarbonate case and is held firmly in place by
spring-type non-return clips. The Metal Surround Case must be
factory installed on the polycarbonate case and once installed,
it cannot be removed in the field.
With the metal case in place, the meter’s standard ratchet-type
mounting clips can not be used. Instead a pair of screw-type
DIN standard mounting clips are provided, which clip into holes
on the side of the metal case and tighten against the rear of the
panel. A ground tab on the metal case enables the metal case
to be easily connected to the panel ground.
