Leprecon LD-340 DMX Series - Manual (Page 4)

Installation and Use
Mounting
The LD360 dimmers are passively cooled, using no internal fans or other noisy cooling devices.
The heat generated by the dimmer is dissipated by the metal chassis. For this reason, it is
necessary to 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 with standard Edison plugs attached.
The LD360 dimmer can present up to a 20 Amp load per line cord; use of extension cords for
power is not recommended. The LD360 should be connected to a service capable of supplying 20
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 provided with standard duplex outlets. The capacity of these outlets is
15 amps each. Lamp loads are plugged directly into the outlets on the body of the dimmer.
Address Selection
The LD360 DMX dimmer can be set to respond to any control channel from 1 to 512. Three
thumbwheel switches are provided for easy address setting. Just set the switches to read the
correct start address. The address shown on the switches is the address for the first channel of
the dimmer. Examples follow:
Start Address: Pack Range
1 channels 1-6
2 channels 2-7
5 channels 5-10
Status LED
The LED labeled ‘status’ on the end panel of the LD360 DMX can be useful for locating problems
