Connecting the Cisco ISA 3000
Step 4
Using a 18-gauge (1.02mm) wire-stripping tool, strip the ground wire and both ends of the twisted pair wires to 0.25 inch
(6.3 mm) ± 0.02 inch (0.5 mm). See the following figure, number 1. Do not strip more than 0.27 inch (6.8 mm) of insulation
from the wires. Stripping more than the recommended amount of wire can leave exposed wire from the power and relay
connector after installation.

Step 5
Remove the two captive screws that attach the power connector to the device, and remove the power connector. Remove
both connectors if you are connecting to two power sources.
Step 6
On the power connector, insert the exposed part of the positive wire into the connection labeled "+" and the exposed part
of the return wire into the connection labeled "–". The "+" is the Power source positive connection, and the "-" is the
Power source return connection. See the following figure.

Note Ensure that you cannot see any wire lead. Only wire with insulation should extend from the connector.
Step 7
Use a ratcheting torque flathead screwdriver to torque the power connector captive screws (above the installed wire leads)
to 2 in-lb (0.23 N-m). See the following figure.
Do not over-torque the power connector's captive screws. The torque should not exceed 2 inch-lbs (0.23 N-m).
