3) Installation
Mounting
The ULD-360 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 ULD-360 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 LD360 series dimmers are supplied with line cords that have standard Edison
plugs attached. Each line of the LD360 should be connected to a service capable of
supplying 15 amps 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 LD360 dimmer, consult with a qualified electrician.
Load Connection
The LD360 DMX dimmer is offered in several different models. Options include stage
pin, Nema 5-15 duplex, and Nema L5-20. Lamp loads are plugged directly into the
outlets on the body of the dimmer.
4) Turning on Power
The ULD-360 has one line cord and circuit breaker, and the ULD-360HP has two of
each, as illustrated previously. On the HP model, the line cord and breaker to the left on
the endplate, labeled ‘A’, supplies power for channels 1-3, as well as the internal power
supply for the control electronics. Line cord and breaker ‘B’ supplies power to channels
3 through 6.
Power applied to the dimmer is signaled 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.
