4.4.1
Input Power Supply
The GEN·VI dimmer must be fed from a suitable external circuit breaker.
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 nominal input voltage is 220-240 Volts. 3-phase Star (380-415V). 50-60Hz. 100-120VAC
versions are available by special order from the factory.
The GEN·VI can be powered from,
•
Three phase supply of nominal or 220-240VAC* at 50 - 60Hz of up to 52 Amps per phase.
See Neutral rating note above.
•
Single phase supply of nominal or 220-240VAC* at 50 - 60Hz of up to 65 Amps (maximum).
Safety Note: Conversion between three phase and single phase operation should only be
undertaken by a suitably trained and qualified electrical technician.
4.4.2
Wallmount GEN·VI Power Input
There are a number of possible entry points to connect the incoming three phase supply,
•
For hard-wired installations, there are two large knock-out panels located on the upper left
hand region. These knock-out panels allow wiring to enter and exit the dimmer via cable
ducting on top or direct through a wall cavity at the rear.
•
For portable or installation situations where a flexible three phase tail and plug are required,
a 32mm diameter hole exists on the upper left side. A hole plug is supplied to cover this
hole when the product is shipped. By removing this plug, a correct size metal or plastic
strain-relief gland can be fitted to secure the three phase tail to the chassis.
4.4.3
DMX512 Connections
DMX 512 is the industry standard for the transmission of digital control signals between lighting
equipment. DMX is usually “looped” from one piece of equipment to the next.
DMX 512 is connected to the dimmer via the
front panel 5 pin XLR “DMX INPUT” socket.
A “DMX THRU” socket provides a loop output to feed other DMX equipment.
Rackmount Wallmount
If the DMX line ends at this dimmer (is not looped to other dimmers or devices) then the DMX TERM
switch must be set to TERM using the touch screen. See section 5.9
LSC recommends the use of RS485 data cable or shielded CAT5 cable for the DMX connections.
Audio or Microphone cables must not be used.
