1) General Information
Leprecon dimming systems are fully assembled and tested before shipment. When the
dimming system arrives:
•
Check for visible signs of damage to enclosure. Immediately report any damage
to your shipper.
•
Inspect the configuration and confirm that it matches your order. If a discrepancy
is discovered, contact the Leprecon Service Department at (888) 422-3537. Our

2) System requirements
a) Proper Overcurrent Protection
Dimming systems are required by National Electrical Code to be supplied by a
properly sized breaker.
There are instances were the rack can be supplied by a breaker and wiring with
capacity that is less than the full load capacity of the dimming system. For details on
overcurrent protection requirements see NEC section 520.27.
b) Supply and Load Wire Type
Use copper conductors only for wiring Leprecon Dimming Systems. UL requires the
use of 90 degree rated conductors with the ampacity calculated using 75 degree
tables. Section 4 of this manual will provide the fully loaded power requirements for
your Leprecon system. NEC and local codes must be consulted to determine correct
conductor sizes for each system.
c) Clearance and Airflow
Leprecon Dimming Systems are rated for operation with an ambient temperature of
40 degrees Celsius (104 degrees F) or less. Internal fans allow full load operation as
long as this ambient temperature is not exceeded.
Sufficient clearance must be provided to access and fully open the dimming cabinet
front and back doors for service. Doors are 19” wide, and can be easily removed for
easier installation.
d) Cooling requirements
When planning for HVAC load, the following information can be used. Each 20 amp
VX or MX 12 channel pack will generate approximately 2448 BTU per hour when
fully loaded and operated at 100% output.
e) UL Listing
Leprecon installation dimmer systems are UL Listed. The UL File number for this
product is File E112295
