1.0 Introduction
1.1 Mains supply wiring
THREE PHASE OPERATION ("NORMAL"):
In Australia the HP12-TR / HP12-SC is normally fitted with a flexible supply cable and
32 amp Clipsal plug. The cable has 6mm
2
(40 amp) conductors for the three phases, the
neutral and the earth.
The 32 amp Clipsal plug suits the majority of 3 phase venue outlets in Australia, and will
provide sufficient power to run twelve pairs of 1000 watt PAR64 lamps, assumimg
normal duty cycles.
The incoming mains supply must be protected at not more than 50 amps. The dimmers'
circuit breakers are not rated to correctly clear faults if the supply protection is in excess
of this. Mains supplies are generally protected at lower currents (32 amps or 40 amps at
most Australian venues). It is up to the user to ensure that the dimmer is used in a
manner that does not exceed the available supply capacity.
In Australia the HP6-C is normally fitted with a flexible supply cable and 50 amp Clipsal
plug. The incoming mains supply must be protected at not more than 63 amps. The
dimmer’s circuit breakers are not rated to correctly clear faults if the supply protection is
in excess of this.
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 with a copper link, with the mains neutral connected to terminal
N2.
If the supply cable is damaged, it must be replaced with a cable available from JANDS or
its service agents.
SINGLE PHASE OPERATION:
The dimmers 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 50 amps [63 amps: HP6-C].
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
dimmers' breakers are not rated to clear faults if the supply is protected at currents of
over 50 amps [63 amps: HP6-C].
The neutral-earth detection will act if all three neutrals have more than 15 volts to earth,
or if any one neutral has more than 45 volts to earth.
