Connect DC Power to a PA-7050 Firewall

This topic describes how to connect power to DC power supplies in a PA-7050 firewall. The DC power
supplies require -40VDC to -60VDC power input. For details on power requirements, see "Determine
Power Configuration Requirements" on page 70.
CAUTION: For the DC input circuit, make sure there is a 60-amp protected
circuit breaker, minimum -40VDC to -60VDC, and a double pole on the input to the
DC power. The power cables used to connect DC power are provided with the
PA-7050 firewall, but not the PA-7080 firewall.
1. Read "Cautions and Warnings Related to Working with the Hardware" on page 89 and, for power
configuration planning, see "Determine Power Configuration Requirements" on page 70.
2. Put the provided ESD wrist strap on your wrist ensuring that the metal contact is touching your
skin. Then attach (snap) one end of the ground cable to the wrist strap and remove the alligator clip
from the banana clip on the other end of the ESD grounding cable. Plug the banana clip end into
one of the ESD ports located on the front of the chassis before handling ESD sensitive hardware.
For details on the ESD port location, see "PA-7050 Front Panel (AC)" on page 6.
3. Remove the two nuts and star washers from the ground studs located on the back of the chassis on
the upper left side.
4. Crimp a 6-AWG wire to the provided grounding lug and connect the other end to your earth ground
point.
