QUICK START GUIDE
Step 3- Connect Chassis Ground, DC Reference (CO) Ground, and DC Cables
Connections are on the rear. Not provided: lugs and lug hardware.
CAUTION: Verify battery voltage and polarity with a voltmeter before proceeding.
DANGER: Protect input cables or disconnect all input circuit protectors prior to making connections to the system.
1. Ground chassis - 6 AWG recommended, #10 or 1/4" on 5/8" center lug. Torque to 35 in-lb (4Nm) - 5/16" socket.
Note: Some applications rely on frame mounting screws for shelf ground omitting the shelf ground cable.
Note: Some applications rely on grounding a single shelf of a multi-shelf system, omitting the shelf ground cable on other
shelves.
2. DC Reference Ground - Make a single DC Reference Ground connection to Output Feed Return either at the converter sys-
tem or to the Return bar of external -48V distribution - 6AWG recommended.
3. Install DC cables—Lug Landings: 3/8" on 1" centers. Max tongue width: 1.4" Torque to 240 in-lb (27Nm).
Note: Input Feed Returns must be externally connected to DC Reference (CO) ground.
