The control portion of the dimmer cabinet employs all digital circuitry for accuracy
and for minimum wiring requirements between the dimmer cabinet and its control
systems.
Surface-mount and flush-mount units both include necessary mounting hardware.
Control Overview
The Leviton a-2000D Dimmer Cabinet uses an intelligent central control card
(Digital Main Control Module), enabling the dimmers in this system to dim and
control virtually any incandescent or fluorescent lighting load. The software can
tell a dimmer module whether it is to be a dimmer or a non-dim, tell it what type
of fluorescent dimmer ballast it will operate, and set up the required parameters
to properly drive virtually any type of fluorescent dimmer ballast. You can use
three different types of control input signals, Luma-Net III, DMX512 and 0-10VDC
(with optional Analog Card) to control the dimmers. The LCD display provides an
easy user interface.
Mounting - Surface or Flush Mounted?
The 12 and 24 circuit dimming cabinets comes standard for surface mounting. In
order to flush mount the unit, you must use the appropriate flush mount
hardware kit. Consult the factory for the appropriate kit.

Stacked Mounting
The following cabinets can be joined together vertically and wired with a single
feed:
•
12+24 - Factory only.
•
24+24 - Field or factory. Field kit part number A2K24-Kit
This can be accomplished in the factory or the field using a UL listed bussing kit.
Cooling Fans
Both surface and flush-mounted units contain fans for cooling. They are relatively
quiet, but this unit should not be mounted where minor fan noise is objectionable.
The fans are rated at 41 dBa each. The fan(s) are normally off when the system is
off, and comes on when any dimmer comes on.
Cooling Fan dust covers should be removed and cleaned with compressed air or non
abrasive cleaning agent every 6 months for optimum fan operation.
