Figure 1-15 Cisco ONS 15454 Power Terminals
Step 4 Remove or loosen the #8 power terminal screws on the ONS 15454. To avoid confusion, label the cables
connected to the BAT1/RET1 (A) power terminals as 1, and the cables connected to the BAT2/RET2
(B) power terminals as 2.
Note Use only pressure terminal connectors, such as ring and fork types, when terminating the battery,
battery return, and frame ground conductors.
Caution Before you make any crimp connections, coat all bare conductors (battery, battery return, and frame
ground) with an appropriate antioxidant compound. Bring all unplated connectors, braided strap, and bus
bars to a bright finish, then coat with an antioxidant before you connect them. You do not need to prepare
tinned, solder-plated, or silver-plated connectors and other plated connection surfaces, but always keep
them clean and free of contaminants.
Caution When terminating power, return, and frame ground, do not use soldering lug, screwless (push-in)
connectors, quick-connect, or other friction-fit connectors.
Step 5 Strip 1/2 inch (12.7 mm) of insulation from all power cables that you will use.
Step 6 Crimp the lugs onto the ends of all power leads.
Note When terminating battery and battery return connections as shown in Figure 1-15, follow a
torque specification of 10 in-lb.
