Do not mount in ambient temperatures exceeding published limits. Electrical ratings stated in literature and on nameplates should not be exceeded. Overload on a control relay can significantly reduce control life. Always wire devices to national and local electrical codes, using wire sizes recommended in UE literature. Note warning signs such as drift in set point or indication.
Check controls immediately.
Perform internal adjustments and wiring only as recommended. Observe polarity for all plug-in components. Protect solid state and mechanical output relays from overload by use of properly rated external fusing. The use of any relay output beyond its published limits for current, voltage or life could result in permanent control damage. Consult factory as needed.
