Isolation plate for CMSS 600, CMSS 606, and
CMSS 620-2 Drivers
The CMSS 600, CMSS 606, and CMSS 620-2
Drivers have a metallic case and must be
electrically isolated from the mounting surface
to prevent ground-loop problems.
The Isolation Plate is especially important with
installations in hazardous locations that use
Intrinsic Safety Barriers.
Figure 4-7 shows how to install the isolation
plate. Use non-metallic screws or use inserts
so screw doesn’t provide continuity.
Figure 4-8 shows a DIN-rail with various
components attached.

Weatherproof housings for protection from adverse
environmental conditions
SKF Condition Monitoring product line offers three types of
housings to provide protection from adverse environmental
conditions for DIN-rail mountable eddy probe drivers.
Water resistant housing
Enclosures are intended for indoor or outdoor use primarily
to provide a degree of protection against corrosion,
windblown dust and rain, splashing water, and hose-
directed water; undamaged by the formation of ice on
the enclosure. The housings are constructed of 14 or 16
gauge steel with seams continuously welded. Holes and
cable clamp fittings are provided. The cover is held in place
by steel clamps on four sides of cover to assure water tight
integrity. There is an oil-resistant gasket held in place with
oil resistant adhesive. Finish is ANSI 61 gray polyester
powder coating. Meets NEMA 4 criteria.
Water and corrosion resistant housing (Stainless steel)
Meets the same criteria as the Water Resistant Housing in
addition to being manufactured of stainless steel to meet
the CORROSION RESISTANT criteria. Finish is unpainted
polished surface. Meets NEMA 4X criteria.
