Hardware Installation
Remove or loosen the #8 power terminal screws on the ONS 15454. To avoid confusion, label the cables
Step 3
connected to the BAT1/RET1 power terminals as 1, and the cables connected to the BAT2/RET2 power
terminals as 2.
Note
Caution
Caution
Step 4
Strip 1/2 inch of insulation from all power cables that you will use. Crimp the lugs onto the ends of all
power leads.
Note
Step 5
Terminate the return 1 lead to the RET1 backplane terminal. Use oxidation-prevention grease to keep
connections non-corrosive.
Warning
Step 6
Terminate the negative 1 lead to the negative BAT1 backplane power terminal. Use oxidation prevention
grease to keep connections non-corrosive.
Step 7
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 non-corrosive.
Route the cables out below the power terminals using the plastic cable clamp.
November 2001
Use only pressure terminal connectors, such as ring and fork types, when terminating the
battery, battery return, and frame ground conductors.
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.
When terminating power, return, and frame ground, do not use soldering lug, screwless
(push-in) connectors, quick-connect, or other friction-fit connectors.
When terminating battery and battery return connections as shown in
torque specification of 10 in-lbs. When terminating a frame ground, use the kep-nut provided
with the ONS 15454 and tighten it to a torque specification of 31 in-lbs. The kep-nut provides
a frame ground connection that minimizes the possibility of loosening caused by rotation
during installation and maintenance activity. This type of prevention is inherently provided
by the terminal block for battery and battery return connections.
Do not secure multiple connectors with the same bolt assembly.
