LIMITS OF 16-33 VOLTS USING FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR). DO NOT
APPLY 80% AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION.
WARNING: FOR ULC APPLICATIONS THIS APPLIANCE WAS TESTED TO THE OPERATING VOLTAGE
LIMITS OF 20-31 VOLTS USING FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR). APPLY
80% AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION.
WARNING:
MAKE SURE THAT THE TOTAL RMS CURRENT AND TOTAL AVERAGE CURRENT
REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM'S PRIMARY AND SECONDARY
POWER SOURCES, SIGNALING CIRCUITS, SM, DSM SYNC MODULES AND WHEELOCK'S POWER
SUPPLIES DO NOT EXCEED THE POWER SOURCES' RATED CAPACITY OR THE CURRENT RATINGS OF
ANY FUSES ON THE CIRCUITS TO WHICH THIS APPLIANCE IS WIRED. OVERLOADING POWER SOURCES
