7 MAINTENANCE

Before attempting any maintenance work the following must be performed:

1. Ensure the unit is powered off and isolated from the mains.

2. Ensure the battery isolation switch on the front panel is switched to ‘OFF’.

3. Remove all connectors that interface with external equipment (as some of these

may have mains potential voltages present on them).

If multiple I/O boards are fitted make a note of the board address against

the plugged in loom before removing along with the position of each

connector (top & bottom position).

4. Remove the unit from its mounted position.

7.2 Regular Maintenance

inspection of other equipment on site. On these visits, trained personnel must switch off

the mains power to the controller and the unit.

General inspections of the unit in situ for any contamination, overheating

of components, corrosion or battery leakage. Rectify where necessary.

Annual

necessary.

Annual
