Connect Power to a PA-220R Firewall
Connect DC Power to a PA-220R Firewall
The following procedure describes how to connect DC power to a PA-220R firewall. Before you
connect power, read the PA-220R Electrical Specificaons and Prepare to Connect DC Power to
a PA-220R Firewall . The DC terminal block for connecng the DC power cables to the firewall is
included in the PA-220R accessories kit.

Power off the DC power sources that you will connect to the power supplies before you
connue.
STEP 1 | Verify that the DC power source that will power the firewall is powered off.
In the following procedure, connect the DC power cables—and ground cable if you do
not use the screw-on ground point—to the DC terminal block before you aach the DC
terminal block to the firewall.
STEP 2 | Connect one end of a 16-22AWG ground cable to the firewall and connect the other end to
earth ground. There are three ground locaons on the firewall: one screw-on ground point
above the DC power inputs and two ground inputs on the DC terminal block (last two inputs
to the right of the DC inputs); use only one of the three ground locaons even if you will
connect a second set of DC power cables for redundancy.
• Screw-on ground point ( Opon 1 ) —Remove the ground screw from the screw-on ground
point, hold the 6-32 ring lug (that you previously aached to the ground cable) over the
screw hole, and then re-aach the screw to secure the cable to the firewall. Do not torque
the screw to more than 6 in-lbs.
• DC terminal block ground inputs ( Opon 2 ) —Insert the cable into one of the two ground
input terminals and then secure the cable by turning the flat-head terminal screw clockwise.
Do not torque the terminal screws to more than 2 in-lbs.
