2.6 CONNECTIONS
Connections are provided behind the front covers for power input, DMX control, Wallplate
control, Panic control and load power. All control circuit wiring should be isolated from the
power cabling by a metal conduit run up to the control circuit connectors.
12 channel Redback with front covers removed.
2.6.1 Input Power Supply
The Redback Wallmount dimmer system must be fed from a suitable external circuit
breaker. The optional RCD input breaker provides Residual Current Protection only. It does
not protect the input circuit from current overloads. The current ratings of the supply for
each model are listed below.
Note: The rating of the Neutral conductor feeding the dimmer must be at least 1.25 times
that of rated limit of any of the Active phase conductors.
This is because various combinations of dimmer drive will result in a Neutral current higher
than the line current due to the phase control characteristics of these type of dimmers.
For example, a 40Amp 3 phase supply must have a neutral rated at 50Amps.
The input power connection utilizes five 35mm
2 terminals (3 phases, neutral and earth).
The nominal input voltage is 220-240 Volts. 3-phase Star (380-415V). 50-60Hz.
3 phase Delta is also available as a factory option.
2.6.1.1 6 Channel Redbacks
6 Channel Redbacks can be powered from:
 Three phase supply of nominal 220-240VAC* at 50 - 60Hz of up to 20 Amps per
phase. See Neutral rating note above.
 Single phase supply of nominal or 220-240VAC* at 50 - 60Hz of up to 60 Amps
2.6.1.2 12 channel Redbacks
12 channel Redback can be powered from:
 Three phase supply of nominal or 220-240VAC* at 50 - 60Hz of up to 40 Amps per
phase. See Neutral rating note above.
 Single phase supply of nominal or 220-240VAC* at 50 - 60Hz of up to 120 Amps.
