NTP- G18 Connect Office Power to the ONS 15454 ANSI
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 1-18, follow a
torque specification of 10 in-lb.
Step 7 Terminate the return 1 lead to the RET1 backplane terminal. Use oxidation-prevention grease to keep the
connections noncorrosive.
Step 8 Terminate the negative 1 lead to the negative BAT1 backplane power terminal. Use oxidation prevention
grease to keep connections noncorrosive.
Step 9 If you use redundant power leads, terminate the return 2 lead to the positive RET2 terminal on the
ONS 15454. Terminate the negative 2 lead to the negative BAT2 terminal on the ONS 15454. Use
oxidation-preventative grease to keep connections noncorrosive.
Note The configured ONS 15454 shelf can work with a single power line since the ONS 15454 power
configuration offers redundancy. When using the 15454-FTA3 fan tray, if the ONS15454 shelf is
powered by a single power line, the BAT-FAIL alarm appears, the fans run at a maximum speed, and the
system does not comply with NEBS GR-63 Issue 3 and GR-1089 Issue 4 and 5 requirements. In order
to meet the above mentioned NEBS requirements, the ONS 15454 shelf must be powered by both the
DC power lines.
Step 10 Route the cables out below the power terminals using the plastic cable clamp, as shown in Figure 1-18
on page 1-39.
Step 11 Connect the return cables to earth ground at power supply side.
Step 12 Return to your originating procedure (NTP).
