DETAILED STEPS
Step 1
At the rear of the router, check that the power Standby switch is in the Standby position.
Step 2 Ensure that the positive and negative leads are disconnected from the site power source and the source circuit breaker
is turned off.
Step 3 Using a wire stripper, strip the recommended amount of wire insulation which is 15mm (0.6 inch) from the negative,
positive, and ground leads.
Note The stripping length is common to all types of wire used.
Step 4
The following figure shows the wire strip and insulation location.
At the rear of the router, check that the power Standby switch is in the Standby position.
Ensure that the positive and negative leads are disconnected from the site power source and the source
circuit breaker is turned off.
Using a wire stripper, strip the recommended amount of wire insulation which is 15mm (0.6 inch) from
the negative, positive, and ground leads.
The following figure shows the wire strip and insulation location.
Using a 3.5mm screwdriver, insert the screwdriver at an angle to release the spring while you install
the stripped lead wire (see the following figure).
Carefully push the screwdriver at an angle forward until you relieve the spring contact.
With the screwdriver still inserted, gently push the lead wire (ground lead first) in until there is no copper
wire showing as shown in the following figure.
Make certain no copper wire is visible as shown in the following figure which shows the lead wire fully
inserted.
After the lead wire is fully inserted, hold the lead wire in place by pressing inward while you remove
the screwdriver to release the spring to tension down on the installed lead wire, then perform these steps:
Repeat Steps 5 through Step 10 for each lead wire. The following figure shows the leads wires installed
in the terminal block.
After inserting the ground wire leave an extra service loop in the ground lead to ensure that the ground
lead is the last lead to disconnect from the power supply if a great deal of strain is placed on all three
leads as shown in the following figure, callout 1.
