Installation

Info:

 The DC terminal/Hex nuts on the CSW1012 and CSW2012 

are made of stainless steel, which has a high likelihood of galling 
or thread seizing while being tightened—causing the bolts to 
strip or to snap/break off. Use an anti-seize lubricant, tighten the 
fasteners slowly (@low rpms) without interruption, and apply only 
light pressure.

2.4.5  Wiring the Battery Bank

WARNING:

 Lethal currents will be present if the positive and 

negative cables attached to the battery bank touch each other. 
During the installation and wiring process, ensure the cable ends 
are insulated or covered to prevent touching/shorting the cables.

Info:

 DO NOT connect the DC wires from the battery bank to 

the inverter until 1) all DC wiring is complete, 2) the correct DC 
overcurrent protection has been installed, and 3) the correct DC 
voltage and polarity have been veri

fi

 ed.

Depending upon the voltage of the batteries (6 or 12 VDC), the batteries 
must be wired in series, parallel, or series-parallel to provide the correct 
voltage. The interconnecting DC wires must be sized and rated exactly the 
same as those used between the battery bank and the inverter.
Place the batteries as close as practical to the inverter, preferably in an 
insulated and ventilated enclosure. Allow adequate space above the batteries 
to access the terminals and vent caps (as applicable). Also, allow at least 1” 
(2.5 cm) of space between the batteries to provide good air 

fl

 ow. DO NOT 

mount the batteries directly under the inverter.

CAUTION:

 Install batteries in a well ventilated area. Batteries 

can produce explosive gasses. For compartment or enclosure 
installations, always vent batteries to the outside.

Info:

 To ensure the best performance from your inverter system, 

batteries should be of the same size, type, rating, and age. Do not 
use old or untested batteries.

2.4.6  Wiring the Inverter to the Battery Bank

CAUTION:

 The inverter is NOT reverse polarity protected—if the 

positive terminal of the battery is connected to the negative terminal 
of the inverter and vice versa, severe damage to the inverter will 
occur and this will void the warranty. Before connecting the DC 
wires from the batteries to the inverter, verify the correct battery 
voltage and polarity using a voltmeter. If necessary, color code 
the cables (with colored tape): red for positive (+), and white for 
negative (-) to avoid polarity confusion.

Info:

 The DC overcurrent device (i.e., circuit breaker or fuse) must 

be placed in the positive (red) DC cable line between the inverter’s 
positive DC terminal and the battery’s positive terminal (red)—as 
close to the battery as possible. For maximum protection, install it 
within 18 inches (45 cm) of the battery.
