Helpful Tips:
•
Power cabling for paralleling PHI Batteries is not included. All wire should be an appropriate gauge
and construction to handle the loads that will be placed upon it. Heavy gauge, high strand copper
wire is the industry standard due to its stability, efficiency and overall quality.
•
Each PHI Battery’s i
ndividual wire runs are typically sized at 4 AWG, according to the 80A built-in
breaker.
o
Conductor ampacity can be determined using National Electrical Code tables.
o
Depending on the electrical code of the local Authority Having Jurisdiction, the PHI
Batter
y leads’
gauge may need to be sized according to the built-in breaker or according to
the PHI Battery’s surge rating.
•
Arctic Ultraflex Blue® cables from Polarwire are flexible and easy to work with:

•
Battery cables can be custom ordered to include the
3/8” lugs
that fit on the PHI Battery’s threaded
studs.
•
Determine the cable length for the PHI Battery terminal farthest from the common busbar or plate
first.
•
Additional cabling or slack that remains with the shorter distance runs can be coiled
and secured with Zip Ties.
•
Wire length should be kept as short as practical.
•
Positive wire runs should be separated from negative wire runs in separate conduit.
•
Energy supplied by the PHI Battery is reduced as electrical current moves through wire. For lengths
of battery cable greater than ~10 feet (3 meters), ensure that the voltage drop is no greater than 3%.
•
To take full advantage of the combined PHI Battery bank’s surge rating, the DC busbars or plates
that the individual PHI Batteries are wired to
should be rated to match the PHI Battery bank’s total
surge rating.

CAU
TION: Do not reverse polarity. Positive battery cables must connect to the PHI Battery’s
Positive terminal studs and to Positive DC busbars or plates. Negative battery cables must
connect to the PHI Battery’s Negative terminal studs and to Negative DC bus
bars or plates.
Reversing polarity will Void the Warranty.
