Due to the various cable
lengths required for a given installation site, DC power and ground
cables are not included with the firewall.
—Use this cable for the ground
cable and DC power cables.
6-32 ring lug
—Use this lug to connect a ground cable to
the screw-on ground point on the firewall. You can, instead, choose
one of the DC terminal block ground inputs.
—Use this tool to strip the cable
shielding off the ends of the DC power and ground cables.
—Use these tools to attach the ground
cable and DC power cables: use a Phillips-head screwdriver for the screw-on
ground point and a small flat-head screwdriver to secure cables to
the DC terminal block inputs.
Measure and cut the DC power cables and ground cable.
Ensure that the DC power cables reach from the firewall to your DC
power source and that the ground cable reaches from the firewall
to your ground location.
You will need one ground cable and two DC cables
(one for the positive connection and one for the negative connection). To
provide power redundancy for the firewall, prepare two additional
DC power cables to connect the second set of DC power inputs.
Prepare the ground cables using one of the following methods
based on which ground location you decide to use:
Screw-on ground point (above the DC terminal
—Strip 1/4-inch of cable shielding from the end of the
ground cable and crimp a 6-32 ring lug onto the end of the cable.
DC terminal block ground input
—Strip 1/4-inch of cable
shielding from the end of the ground cable.
Strip 1/4-inch of cable shielding from the ends of each
DC power cable that you will insert into the DC terminal block.
