Key Description
1 7705 SAR-F chassis
2 Terminal strip with protective cover
3 Disconnect device
4 DC source A
5 DC source B
6 Battery wire
7 Battery return wire
• two or four lengths of wire (#18 AWG minimum) (two lengths per supply)
• torque driver for slot screws
Make the battery return ground connection(s)
connection:
a) Run a length of wire from the power source positive terminal to the terminal strip
on the router.
b) Prepare the end of the wire at the power source according to local safety practices
and attach it to the power source positive terminal.
c) Prepare the end of the wire at the router by attaching a ring lug (see
d) Attach the battery return wire to the correct battery return terminal on the router.
For -48 VDC systems, use the +Batt terminal. Tighten to a torque of 8-10 lbf-in
maximum.
e) For redundant supply configurations, repeat this step for the other battery return
wire.
