8.4 Internal Mains Wiring
The FP12 dimmer has been designed to run from most commonly used power systems.
8.4.1 Normal Three Phase plus Neutral Operation
The FP12 is normally supplied with a three-phase power cable and plug attached, suiting
the vast majority of available mains supplies (ie. three phase and neutral).
The incoming mains supply must be protected at not more than the specified maximum.
Mains supplies are generally protected at lower currents (32 amps or 40 amps at most
Australian venues). It is the responsibility of the user to ensure that the dimmer is used in
a manner that does not exceed the available supply capacity.
The power cable is terminated within the dimmer at a six-way terminal block and an
earthing stud. The six-way terminal block has three poles for the three live mains phases
(labelled A1, A2, A3), and three poles for the mains neutral (N1, N2, N3). The three
neutral poles are bridged by a copper link, with the incoming mains neutral connected to
terminal N2.
8.4.2 Single Phase Operation
The dimmer may be configured for single phase operation where three phase mains
supply is unavailable.
The dimmer should be supplied with three same-phase actives and three neutrals. The
three active lines must each be protected at not more than the specified maximum. The
three neutral conductors must each be rated at the same current as the actives. The earth
conductor should be similarly rated.
The bridge between the three neutral terminal poles (N1, N2, N3) must be removed
before the three incoming neutral lines are connected.
Although it is possible to supply the dimmer with one large single phase feed, the
dimmer’s breakers may not be rated to clear faults if the supply is protected at currents
greater than the specified maximum.
The overvoltage detection will operate as normal.
8.4.3 Delta Supply Operation
The available venue mains supply in some countries (eg. the Philippines) is in the form of
three phases (220 volts between phases) with no neutral connection. The dimmer may be
configured for operation from 220V delta supplies.
