4 Watlow Silver Series OIT Installation Guide
Installation of OITs
CE Compliance
The Silver Series EM Graphic OITs have been tested to conform to
European CE requirements, which meet or exceed the noise emissions
and immunity requirements as set forth in the EN55022 (Emissions) and
EN55024 (Immunity) standards. The products are designed to withstand
electrical noise in harsh industrial environments. They also conform to
requirements that limit electrical emissions. However, this does not
guarantee that the products will be totally immune from possible
malfunction in cases where severe electrical noise occurs. Therefore, we
strongly recommend that you follow the guidelines outlined in this guide
for proper wire routing and grounding to insure the proper operation of
your graphic OIT.
NEMA Rating
The Silver Series EM is rated for NEMA 4 (indoor) or IP65/IP66
installations. This means that when the OIT is properly mounted to a
NEMA 4 panel or other NEMA 4 rated enclosure, the front enclosure of
the OIT will provide protection to the inside of the panel from splashing
water, wind-blown dust, rain, or hose-directed water. The OIT must be
installed according to the instructions in this manual to be properly
sealed.
Environmental Considerations
The Silver Series EM is designed to operate in temperatures from 0° to
50°C (32° to 122°F). It is intended for indoor installations and may not
be suitable for use in certain outdoor applications. Avoid installing the
Silver Series EM touchscreens in environments with severe mechanical
