Installation
Location
Place the 6KW, 12KW and 24KW portable dimmers in a ventilated area free of excessive humidity or condensation and accessible
only to authorized personnel. Typical ambient temperature should be between 0° and 32° C.
Connecting Power and Control Wiring
The FD1-6K dimmer is rated for 6,000 Watts at 120VAC. It equipped with a 60 Amp Stage Pin
plug for power input (60 Amp Joy pigtail in Canada) and is protected by a 50 Amp magnetic
circuit breaker. The FD1-12K is rated for 12,000 Watts at 120VAC. It is equipped with a 100
Amp Stage Pin plug for power input (Series 18 Cam-type pigtail in Canada) and is protected
by a 100 Amp magnetic circuit breaker.
The FD1-24K dimmer is rated for 24,000 Watts at 240VAC. It is equipped with a 100 Amp Stage Pin
plug for power input (Series 18 Cam-type pigtail in Canada) and is protected by a 2-pole,
100 Amp magnetic circuit breaker.
Turn the circuit breaker labeled “Mains Power” off
before making any connections to the dimmer.
Line:
Connect the FD1-6K or FD1-12K panel mounted power input plug to a branch circuit protected 120VAC, 60Hz
power source using a cable that is properly grounded and appropriately rated.
The acceptable input voltage range for this unit is 95-130VAC.
Connect the FD1-24K panel mounted power input plug to a branch circuit protected 240VAC,
60Hz power source using a cable that is properly grounded and appropriately rated. The ac-
ceptable input voltage range for this unit is 190-240VAC, so a 208VAC, 60Hz power source
may be used.
When the power connections are secure, the dimmer may be energized by turning on the
Mains Power breaker. Should the breaker trip, check the power source and cables being used
before resetting. Do not power any of the units from a dimmed circuit.
Load:
The 6KW, 12KW and 24KW portable dimmers can control incandescent and inductive
loads including lamps, fans and magnetic transformers in the dim mode. In the relay mode,
it provides a full sine-wave output and can control additional load types, however care must
be taken to assure that non dimmable loads are only operated in the relay mode. Be sure to
include transformers in load calculations.
For safety, and to avoid the wear and tear associated with hot patching, the Mains Power circuit
breaker should be switched off before connecting the load. To prolong lamp life, set the control
output to zero or a pre-heat level before energizing the load. Plug load(s), up to the capacity of the dimmer, into the power
output receptacle using properly grounded and appropriately rated cables.
Control:
For control using USITT DMX512-A data protocol, plug control cables constructed for this use into the 5-pin
XLR connectors labeled “DMX512 In” and “DMX512 Thru” (if cable run continues beyond this unit). DMX512 rules
require the use of a plug-in terminator on the last unit in a DMX daisy chain. The termination plug should be plugged into
the “DMX512 Thru” receptacle.
Note
: FD1 units are not self-terminating.
The LED on the control panel labeled “DMX Data” will Illuminate when control data is present.
