4.
Insert the stripped end of the ground lead all the way into the ground lead receptacle on the –48 VDC
input power supply, and tighten the receptacle screw using a 3.5 mm flat-blade screwdriver to a torque
of 0.5 to 0.6 Nm.
5.
Insert the stripped end of the positive lead all the way into the positive lead receptacle and tighten the
receptacle screw using the same 3.5mm flat-blade screwdriver.
6.
Repeat this step for the negative lead.
7.
After tightening the receptacle screw for the ground, positive, and negative –48 VDC-input leads, use
a cable tie to secure the three leads to the power supply faceplate, as shown in
1002-X Router –48 VDC Power Supply Terminal Block Cable Connections, on page 35
. When securing
the ground, positive, and negative –48 VDC-input leads to the power supply faceplate, leave a small
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
1002-X Router –48 VDC Power Supply Terminal Block Cable Connections, on page 35
.
8.
Connect the ground, positive, and negative leads to the power source.
9.
Turn the branch source breaker on.
10.
Place the –48 VDC Standby switch in the On (|) position. The power supply LEDs light when power
is supplied to the router.
