2) Use the chart below to determine minimum gauge
for wires depend ing on the particular model and the
length of the run from the PM to the load or distribution
DC Wire Size Table:
Model Minimum Wire Size per N.E.C. AWG (mm)
PM-48-20 #14 (2.5 mm)
PM-24-40 #8 (10 mm)
PM-12-80 #4 (25 mm)

To minimize line loss at lengths greater than 5 feet, it is
recommended to increase wire size one gauge for each
additional 5 feet of cable run.
Note: When the PM is used in a parallel n+1 redundant
configuration, output current is derated by 10 % due
to current sharing tolerances (see SPECIFICATIONS
section).
Typical single PM wiring schemes are illustrated
in Figures 3-4.
