2 GETTING CONNECTED
2.1 Input Supply
ePRO dimmers are designed to be connected to a
3 phase supply and are supplied with a 1.2m long
5 wire (6mm²) black rubber insulated power cable
terminated inside the dimmer.
Australian models are fitted with a 5 pin three
phase plug. The ePRO power plug is rated at 40
Amps per phase.
Export models have the end of the cable
unterminated, numbered and fitted with ferrules,
ready for termination into a suitable three phase
plug. Permanent installation models have a
special screw termination rear panel that provides
five 16mm² pressure pad screw terminals to
connect incoming three phase supply.
Connection is Three Phase Star; however other
versions such as single phase(s), two phase and
Three Phase Delta wiring are available upon
request from the factory. Contact LSC Lighting
Systems or your nearest Distributor for further
information.
LSC recommends an overrated Neutral (1.5 times
phase current) on the incoming supply for optimal
performance and minimal interruption. The
incoming supply should also be fused or fitted
with a suitably rated circuit breaker.
2.2 DMX Control Input
The dimmers are designed primarily to accept
control signals conforming to the DMX512A
protocol. The DMX input connector is located on
the front control panel. A Thru connector located
next to the Input allows the connection of the
dimmer to other DMX512 devices downstream.
The Thru connection is passive and allows for the
pass through of the DMX512 signal, even if there
is no power to the dimmer. The ePRO dimmer
has an auto-terminating DMX circuit that will
terminate the network when no thru connection is
present.
LED’s on the front control panel indicate the
condition of the incoming DMX data. Valid data is
indicated with a Green “DMX data” LED. Bad data
is indicated with a Red “DMX error” LED.
2.3 Load Connection
The ePRO dimmers are available with a wide
selection of output load connectors to suit the
many applications and countries of installation.
Wiring details for the Multipole connector options
are detailed in
load socket wiring section .
For Australian versions, the 12 channel ePRO is
supplied with twelve 15 Amp Australian Sockets
and the 6 channel 25A ePRO is supplied with 6
sets of 25 Amp and 15 Amp Australian Sockets
connected in parallel.
European versions of ePRO are available with the
following socket types: Shuko, 16 pole Harting, 19
pole Socapex and a screw terminal version for
permanent installations.
Care should be taken when driving inductive
loads as not all of these types of loads can be
dimmed. If you are in doubt to the dimmers
suitability for the intended application, please
consult LSC Lighting Systems or your nearest
Distributor for further information.
Under all circumstances during the operation of
the dimmer, it is highly advisable not to connect or
disconnect the load while live, to prevent potential
damage to the dimmer, the load connectors or to
the load itself.
2.4 Overload Protection
Each dimmer channel is fitted with fast acting
thermal magnetic Miniature Circuit Breakers
(MCB’s) or optionally with Residual Current
Breakers with Overload (RCBO’s). Under normal
operating conditions the MCB/RCBO pass the
rated current and will only trip when there is an
overload through the dimmer circuit. Likewise, if
there is a short circuit on the load or faulty wiring
on the load side, the MCB/RCBO will trip to
protect the internal components of the dimmer.
When RCBO’s are fitted, they provide the added
protection against earth leakage fault currents.
Dimmer channels can be manually disabled by
switching off the MCB/RCBO for that particular
channel. This is particularly useful for those
occasions where a genuine fault has occurred.
2.5 Dimmer Installation
The ePRO dimmers have been designed to be
either free standing or 19” Rack mountable.
In free standing applications, all dimmers have
four rubber feet attached to the bottom of the
chassis.
If the dimmer is used for touring applications in a
Roobar frame, LSC can provide optional Roobar
mounting brackets to secure the back of the
dimmer.
