Connectors
Powerpole
®
connectors can be installed by soldering or crimping. Crimping is
recommended for the best connection. Be sure to make good connections.
For detailed Powerpole

connector installation tips see RIGrunner support

Power loss is minimized by using short cables of a high (lower number)
gauge (AWG) cable. Go to the following website:
www.westmountainradio.com/calculators
to determine the trade-offs with
cable loss. Select the “Find Cable Size” option and fill in the information.
The calculator will show the percentage of power loss in the cable. For
example, at 100W, a 6 foot 10 AWG cable will have a 2% loss; whereas a 16
AWG cable will have 8% loss.
Connecting the vehicle
The cable to the vehicle’s 12V battery should be 10 AWG and the length
should be as short as practical. Note that West Mountain Radio carries 3, 6
and 10 feet long supply cables, 10 AWG red and black insulated cable with
ring terminals on one end and Powerpole
®
on the other.
Be sure the RED Powerpole connects to the RED wire and connect to the
PLUS terminal on the vehicle battery. Similarly, make sure that the BLACK
Powerpole
®
connects to the BLACK wire and connect to the NEGATIVE
terminal on the battery. Check that the connections at the vehicle are well
tightened.
