Fix
Replace the front panel door plate by attaching the ribbon cable lead and fixing with the door hinges.
Attach all plugs ensuring they fit squarely into the connectors.
Do not connect battery until the master has been powered up on mains.
Powering UP
Carefully check the outstation wiring then apply AC power to each Compact master unit - DO NOT commission on
batteries as the power supply has a large reservoir capacitor which may rupture the battery fuse if the AC is not present when
powering up the system. Once the system is powered, the battery leads can be attached to the battery.
