3) Installation

Mounting

The ULD340 is designed for vertical mounting. The top hanging bracket has a
pre-punched hole for a standard ½" pipe clamp mounting bolt. Using this
mounting point allows the dimmer to be mounted with the power cords, DMX
display and DMX control connectors facing downward.
The ULD340 dimmers are passively cooled, using no internal fans. The heat
generated by the dimmer is dissipated by the extruded metal chassis, and the
airflow through the chassis vents. For this reason, mount the dimmer so that air
is free to circulate around the dimmer. The dimmer should be mounted with at
least 12 inches of clearance between the dimmer and any ceiling or obstruction
above the dimmer that would block air circulation.

Power Connection

Leprecon LD340 series dimmers are supplied with line cords which have
standard TLG plugs attached. Each line of the LD340 should be connected to a
service capable of supplying 15 amps @ 100% duty cycle and protected by a
properly sized circuit breaker.
If you have any questions about the suitability of the power circuit that you
intend to use with the LD340 dimmer, consult with a qualified electrician.

Load Connection

Lamp loads are plugged directly into the outlets on the body of the dimmer.

4) Turning on Power

The ULD-340 has two line cords and two circuit breakers. The line cord and
breaker to the left on the endplate, labeled 'A', supplies power for channels 1
and 2, as well as the internal power supply for the control electronics. Line cord
and breaker 'B' supplies power to channels 3 and 4.
Power applied to the dimmer is indicated by an internal green indicator in each
of the breakers. If the breaker is on, but not lighted, there is no power to the line
cord. Turning on breaker 'A' will also light the red LED display.
Note:
The unit can be Reset to original factory settings by depressing and holding the
ENTER switch while turning on the first breaker.
