2.1 SAFETY
All electrical work must be carried out by suitably qualified persons.
2.2 UNPACKING
The GenVI dimmer is fully tested and inspected before leaving the factory. Upon delivery,
inspect the dimmer for signs of damage or mishandling. In the event of any damage, contact
your LSC agent.
2.3 CONNECTIONS
2.3.1 Input Power Supply
The GenVI 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. 3 phase
Delta and 100-120VAC versions are available by special order from the factory.
The GenVI 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.
Safety Note: Conversion between three phase and single phase operation should only be
undertaken by a suitably trained and qualified electrical technician.
2.3.2 Connecting DMX512
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. 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. See section 3.11
LSC recommends the use of RS485 data cable or shielded CAT5 cable for the DMX
connections. Audio or Microphone cables must not be used.
