for proper wire routing and grounding to insure the proper operation of
your graphic OIT.
NEMA Rating
The Silver Series is rated for NEMA 4/12 (indoor) or IP65 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 is designed to operate in temperatures from 0 to 45 °C
(32 to 113 °F). It is intended for indoor installations and may not be
suitable for use in certain outdoor applications. Avoid installing the
Silver Series OITs in environments with severe mechanical vibration or
shocks. Do not install the OIT in enclosures with rapid temperature
variations or high humidity. Either will cause condensation of water
inside the device and eventual damage to the OIT.
Safety Precautions
Please observe the following precautions when installing the OIT.
Failure to comply with these restrictions could result in loss of life,
serious personal injury, or equipment damage.
Warning: Do not operate the OIT in areas subject to explosion
due to flammable gases, vapors, or dusts.
Warning: Do not connect the OIT to an AC power source. You
will cause permanent damage to the OIT.
Warning: Do not attempt to use a DC power supply that does
not meet OIT power requirements. You may cause malfunction
or permanent damage to the OIT.
Warning: Do not power the OIT with a DC power supply used
for inductive loads or for input circuitry to the programmable
logic controller. Severe voltage spikes caused by these devices
may damage the OIT.
