ONS 15454 power terminals

RET 1

BAT 1

CAUTION: Remove power from both

the BAT1 and BAT2 terminal blocks

prior to servicing

Use only pressure terminal connectors, such as ring 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. 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.
