1.2.2 Output
Connections
Before connecting the Battery and/or DC loads, it is recommended to apply AC power and set the configuration
for the correct output. See section 2.3 for the configuration instructions. Once the configuration is set remove
AC power from the main breaker to the charger.
Select proper size for the DC wiring from the wire size table above (Table 3). If the distance between the unit’s
DC output and the DC load exceeds 10 feet, use the Power Cable Guide below to minimize the voltage drop
across the wire distance.

1.2.3 Power Cabling Guide
Use the following formulas and table to determine proper wire size for minimal voltage drop.
Table of Conventions
CMA = Cross section of wire in circular MIL area
A = Ultimate drain in amperes
LF = Conductor loop feet
MaxAmp = Maximum allowable amperes for given voltage drop
AVD = Allowable voltage drop
K = 11.1 for commercial (TW) copper wire (KS5482-01)
= 7.4 for aluminum (KS20189)

CAUTION: When connecting the DC cables to the
battery, be certain the positive terminal of the charger
is connected to the positive battery terminal and the
negative terminal is connected to the negative battery terminal.
