5 Maintenance

WARNING

The CLMD12 DC 12 Channel Load Module is operated under remote control.
Before servicing any load device connected to the CLMD12, you must first
disconnect the wire between the CLMD12 load terminal and the load device.
Failure to do so can result in serious bodily harm.

Regular maintenance is important to ensure continued proper operation of the Maretron
CLMD12. Perform the following tasks periodically:
