Inspecting and cleaning the enclosure
Inspecting the enclosure and keeping them clean can help prolong the proper functioning of the module.
Before You Begin
CAUTION
Disconnect the voltage supply before servicing or performing any maintenance
operations.
WARNING
Secure the screws on the enclosure once the wiring is completed or when servicing.
• Every few months, open and inspect the enclosure for moisture or dust build-up.
WARNING
Only maintenance personnel and service personnel can do that.
• Using a damp cloth, wipe clean the exterior of the enclosure.
WARNING
Do not pressure wash the controller.
Inspecting and tightening the connections
At some point, the electrical connections must be verified to ensure the connections are not loose and the
installation is always safe. The inspection ensures that no overheating occurs on the electrical
connections.
AP/Cumberland recommends the connections on power and control terminals to be verified every 3-12
Months. Look at the different paragraphs inside the manual to know what tightening torque is required
according to the specific terminal.
