Prepare to Connect DC Power to a PA-220R Firewall

Use the following informaon to gather and prepare the hardware that is required to
Power to a PA-220R
Due to the various cable lengths required for a given installaon site, DC power and
ground cables are not included with the firewall.
Required Hardware
• 16-22AWG cable—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.
• Cable/wire strippers—Use this tool to strip the cable shielding off the ends of the DC power
and ground cables.
• Screwdrivers—Use these tools to aach 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.
Prepare for the Installaon
STEP 1 | Read PA-220R Electrical Specificaons
STEP 2 | 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 locaon.
You will need one ground cable and two DC cables (one for the posive connecon and
one for the negave connecon). To provide power redundancy for the firewall, prepare
two addional DC power cables to connect the second set of DC power inputs.
STEP 3 | Prepare the ground cables using one of the following methods based on which ground
locaon you decide to use:
• Screw-on ground point (above the DC terminal block)—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.
STEP 4 |
Strip 1/4-inch of cable shielding from the ends of each DC power cable that you will insert
into the DC terminal block.
