How to Connect Cables to Phase 3’s Powersafe Powerlock Box. It controls the connection sequence of high current cable connections practicing FMLB.
Phase 3’s Powersafe Sequential Mating Box controls the connection sequence of incoming / outgoing high current cable connections. The sequence ensures that the Earth connection is made first and disconnected last. (FMLB- First Mate Last Break). The cable connectors are also color coded by wiring color standards to assure no confusion in setup.
NOTE: The Powersafe connectors are mechanically keyed to prevent connection errors.
So it is not possible to plug any other connector other than and Earth keyed connector into this position.
NOTE: When covers are raised the previous connection cannot be disconnected without first closing the cover- for example when the Neutral cover is raised the Earth connector cannot be removed. SKIP Neutral connector step if you have purchased the 4 port Powersafe Box.
When the L3 connector is mated and turned fully clockwise to the locked position, take the key lock and turn the L3 lock clockwise. Turning this lock does two things:
a) It locks the L3 connector in place to prevent accidental disconnection under load and prevents further access to the unit.
b) It switches an integral micro switch, which can be used as a signal path for electrical protection device. A 3 pin connector plug is available which will plug onto the 3 pin connector on the rear of the unit, to allow for connection of such devices.
Turn L3 key lock anticlockwise to release the L3 connector.
Now turn the L3 connector fully anticlockwise and pull out of t he port. Push the cover down.
NOTE: The cover will not fully close at this point, however with the cover raised it will not be possible to remove the next connector.
Now turn the L2 connector fully anticlockwise and unplug.
NOTE: The L3 cover will automatically fully close during this action.
Once all connectors are removed, turn the Earth key lock anti-clockwise. This locks the Earth cover
preventing access to the unit.
