Safety Precautions
Please observe the following precautions when installing the Silver Series 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.
