The total lamp wattage connected to each channel must not exceed the rating of each channel (see
SPECIFICATIONS). For inductive loads, the total lamp volt-amperes plus the volt-amperes of any ballast or
transformer must not exceed the rating of each channel.
NOTE: Some inductive type loads, such as transformers, ballasts, and motors with poor factor power
may cause the dimmer to output DC type current. This may cause the load to draw excessive current and
overheat, causing damage to the transformer, ballast or motor. For this reason, it is necessary to insure
any inductive loads are fused individually for their respective normal operating current.
PERMANENT CONNECTION
The DDS 6000 is available as an optional DDS 6000 Plus - 20 terminal version. This version must be installed
by qualified personnel.
AC Input
Conduit containing line conductors enters pack through one of the knockouts in the top end. The two 20A,
120V, 60Hz, 2 wire line circuits, A and B, are terminated to their respective terminals labeled Line and Line N.
The terminals accept wire sizes 22-8 AWG CU and have a torque rating of 8 in-lbs. Line equipment grounding
conductor, if a wire, terminates to the lug labeled GND. The ground lug accepts wire size 14-6 AWG CU and
has a torque rating of 35 in-lbs. (14-10 AWG), 40 in-lbs. (8 AWG), and 45 in-lbs. (6 AWG).
AC Output
Conduit containing load conductors enters pack through one of the knockouts in the top end. The four 1200 W
max., 120V, wire load circuits, 1 through 4, are terminated to their respective terminals labeled Load and Load
N. Circuits 1 and 2 are supplied from input A, and circuits 3 and 4 from input B. The control power supply is also
supplied by input A. Terminal rating are the same as indicated above for line terminals.
LED INDICATORS
The front panel indicator LEDs indicate the status of the relay.
•
RED — Indicates the firing card is receiving DC power.
•
GREEN — Steady indicates a multiplex control signal is being received.
•
YELLOW — Indicates a respective dimmer channel is active and the LED indicates relative intensity.
CHANNEL FUSES
Each channel is protected by a fuse to help prevent overload and damage to the power control devices used
in the dimmer. Be sure to replace the fuse with the same type of rating. Replacement with the wrong fuse is
dangerous and will void your warranty.
NOTE: Lamps may sometimes cause a temporary “short-circuit” when the filament burns out and
cause the fuse to blow. This is normal and protects the internal dimmer circuitry from damage.

MICROPLEX MULTIPLEX CONTROL WIRING
Microplex is the control protocol used on most Leviton-NSI lighting consoles. This
system uses a single three conductor cable to transmit up to 128 channels of
dimmer control. For short distances (50 feet or less) a standard microphone cable
may be used to carry both the control signal and the DC power source for Leviton-
NSI control consoles. Longer distances may be accommodated with 18 gauge or
better cable to reduce voltage losses of the power supply.
Connect the Microplex control cable to either of the three pin XLR jacks. Since
both jacks are wired in parallel, another control cable may be connected between
the remaining jack and another dimmer pack. Many dimmer packs may be “daisy
chained” together in this manner.
Be sure to set the Channel Address DIP switch as required (see ADDRESSING).
ANALOG 0-10 VDC CONTROL WIRING
Each of the four channels of the DDS 6000 may be operated by an analog
0-10 VDC control voltage. This type of control will provide 0% intensity at 0
volts and 100% intensity at 10 volts. Any or all of the DDS 6000 dimmer
channels may be operated in this manner simultaneously with any multiplex
control input. Each dimmer will respond to the greater of any control inputs.
The analog control input uses a standard 5 pin DIN plug which is available
from most electronics supply houses. Connect each if the positive channel
control wires to the desired dimmer channel input pins of the plug. Connect
the common (ground) control wire to the pin indicated on the diagram. Consult the documentation of the analog
control console or device you are using for the proper connections. The control input impedance is 4.7K ohms.
DMX512 MULTIPLEX CONTROL WIRING
DMX512 is the United States Institute of Theater Technology
(USITT) standard for the digital control of dimmers. Leviton-
NSI DDS dimmer products can be converted from Microplex
to DMX512 digital multiplex with a simple kit available from
your dealer.
DMX512 is the preferred type of control wiring when many
dimmer channels are used, because of the high update rate
and the resistance to interference. It is recommended in
locations subject to electrical noise. DMX512 only requires 3
wires to transmit lighting levels for as many as 512 relay or
dimmer channels. Most of the Leviton-NSI lighting control consoles can optionally use this interface.
Connect the DMX512 cable from the control console to the male input connector. Another cable may be
connected from the female connector to the male connector of another pack. Many dimmer packs may be
“daisy chained” or connected together in this manner.
Be sure to set the Channel Address DIP switch as required (see ADDRESSING).
AUTO LAMP TEST
Whenever DIP switch #8 is in the OFF (down) position and there is no multiplex signal detected, all channel
outputs will come to full intensity. The automatic sequencing feature must be disabled for this Auto Lamp test to
operate.
