be a function of the voltage range and phase mode on some BPS models. If the BPS has more than one
output voltage range, size the wires for the lowest available voltage range as the currents will be highest
in that range.

Cable lengths must not exceed twenty-five (25) feet. For lengths greater than 25 feet, calculate the
voltage drop from the following formula:

2 X DISTANCE X CABLE RESISTANCE PER FT. X CURRENT = VOLT DROP
