Wiring and Connecting the 100W High Voltage Power Supply to the 7705 SAR-A
92 7705 SAR-A Chassis Installation Guide
Step 2. Insert the –VDC black wire from the 100W High Voltage Power Supply into the
–Batt wire receptacle on the router. Tighten the screw to a torque of
3.54 to 4.42 lbf-in (0.4 to 0.5 N
.
m) maximum.
Step 3. Insert the +VDC red wire from the 100W High Voltage Power Supply into the
+Batt wire receptacle on the router. Tighten the screw to a torque of
3.54 to 4.42 lbf-in (0.4 to 0.5 N
.
m) maximum.
Step 4. For redundant power supply configurations, repeat steps 1 to 3.
Step 5. Remove the protective plastic cap from the NEMA 5-15P plug connector on the
power supply.
Step 6. Attach the appropriate power cord to the AC power input end of the power supply:
a. For North American power outlets, use the North American AC power cord.
b. For European power outlets, use the 240V European AC power cord.
Step 7. Plug the AC power cord into the grounded AC power outlet.
Wiring and Connecting DC Power via the 100W High
Voltage Power Supply
Required tools and hardware:
• one 100W High Voltage Power Supply (two are required for redundant power
configurations)
• wire stripper
• torque driver for slot screws; No. 2 slotted blade width, 0.125 in (3.2 mm)
Follow these steps to wire and connect a DC power supply to the –48 VDC power feed inputs
on the 7705 SAR-A terminal block via the 100W High Voltage Power Supply. Figure 20
shows the terminal connections; Table 23 identifies the key items in the figure.
Step 1. Prepare the open-ended DC output wire from the 100W High Voltage Power
Supply by stripping 0.35 in. (9 mm) of insulation from each power cable at the
router end, as shown in Figure 21. Table 24 identifies the key items in the figure.
