Maintain cleanliness of the RMC

Controllers installed as standalone should be free of dust and other contaminants. A clean LCD
ensures that alarms, system messages and programmed data displays are clearly visible.
NOTICE – Equipment damage. Potential electrostatic charging hazard: Clean only with a
damp cloth.
When the controller is installed in an enclosure, keep the enclosure door closed and secured except
during maintenance or service procedures that require access to the RMC and other components in
the enclosure. Inspect the enclosure, door, and access holes regularly to ensure that all seals and
gaskets are clean and intact, and that environmental elements have not reached inside of the
enclosure.
Regularly inspect connected cabling to ensure that protective coverings are in place and intact. If the
installation includes a solar panel, clean the cell surface of the panel regularly to ensure that dust and
Preserve data and configuration.
