drawn. The power supply low voltage and mains wiring should be separately routed.
Power supply is delivered to the controller using the screw terminals of connector P3. Connector
pinout, ordered from left to right, is listed in

+V PWR Power supply. Positive terminal
Used for power stages
Table 2: pinout of connector P3
The controller has two 24 V to 48 V power terminals to independently supply the logic and power
sections. They are named +V LOG and +V PWR. These two supplies can be connected together if
convenient. They share the common negative terminal named 0V. It must be connected to the power
supply negative.
Ensure that the polarity of +V LOG, +V PWR and 0V is correct.
8.3. Light outputs
Light outputs are paired on the two 4-way pluggable screw terminal sockets named P1and P2. It is
possible to use two 2-way connectors in a 4-way socket. The light output connections must not be
paralleled or grounded in any way.
The state of each output is shown by a yellow LED indicator next to the connector.
Make sure you set the correct current rating for a light before using it. See the light datasheet and
manual for details on this topic.
8.3.1. Light outputs 1 and 2
Light outputs 1 and 2 are available on the LD1+, LD1-, LD2+ and LD2- screw terminals of connector
P1. Connector pinout, ordered from left to right, is listed in
Table 3: pinout of connector P1
. Be careful
not to cross-connect the two lights.
