CAUTION:  Equipment Damage 
Never reverse the polarity of the battery cables.  Always use correct polarity. 
 
CAUTION:  Fire Hazard 
Always install a breaker, fuse, or protective device to protect the DC system.

See battery manufacturer’s recommendations 
When installing DC cables: 
  Note minimum sizes in Table 4, but refer to local codes for absolute cable size recommendations. 
  Battery positive and negative cables should be no longer than 3 meters (10 feet) each, to minimize voltage 
loss and other effects. 
  Always install breakers or fuses on the positive cable. 
  The cables listed above are for each inverter in a system.  In a system with multiple inverters, each inverter 
requires its own cables and breakers of the size indicated. 
  The inverter’s battery terminal is a threaded stud which accepts a ring terminal lug.   Use crimped and sealed 
copper ring lugs with 0.79 cm (5/16 in) holes, or use compression lugs. 
  Tie, tape, or twist cables together to reduce self-inductance.  Run positive and negative cables through the 
same knockouts and conduit. 
  Make certain the DC breaker is turned to the off position, or the fuse is removed, before proceeding.

Battery Terminal Covers 
 
 
If present, remove the battery 
terminal covers.  These are made of 
stiff plastic with a snap-on design.  
Remove carefully using a flat 
screwdriver inserted into the slots 
on the sides of each cover.
