Connecting the Battery Cables
WARNING: Make certain that the battery polarity is correct when making
connections to the Model MX28B DC power plant. Incorrect connection
could cause severe equipment damage.
The battery cable connections are located at the top rear of the unit as shown in Figure 3.4-1.
The battery positive (return bus) and battery negative (-48V bus) buses each provide four sets
of 3/8” holes on one-inch or 1-3/4” centers for connecting two-hole battery cable lugs. Connect
the battery cables as applicable using 3/8-16 bolts (not provided) and tighten them with a torque
wrench to 200 in-lbs (23 N-m).
