RECOMMENDED WIRING DISTANCES
Refer to Table C for the recommended maximum distances (transformer to load), which are calculated with a 10 percent voltage drop. Distances
are calculated in feet; values in parentheses are in meters.
POWER CONSUMPTION
Table D contains the estimated power consumption information for each model. These calculations are based on an input frequency setting of
60 Hz for 115 VAC and 50 Hz for 230 VAC.
