5.3.2Cable Sizing Considerations

The battery cable(s) should be sized sufficiently large to limit the voltage drop from the MX28B DC power plant to the battery during charging per system design requirements. The cable (s) must also carry the full load current during battery operation. If assistance is required to determine the necessary cables for the application, contact your sales representative or APC.

5.3.3Connecting the Cables

The battery cable connections are located at the top rear of the unit as shown in Figure 5-5. The battery negative (return bus) and battery positive (+24V) buses each provide two sets of 3/8”-16 holes on a double pattern one-inch and 1 ¾-inch 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.

***** CAUTION *****

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.

5.4 DC SYSTEM GROUNDING

THE NEGATIVE LOAD CONNECTION (RETURN BUS) FOR THE POWER PLANT MUST BE CONNECTED TO THE FACILITY MASTER STATION GROUND. THE CONNECTION SHOULD BE MADE ON THE RETURN BUS IN THE BASE UNIT DISTRIBUTION AREA. DETAILS FOR THIS CONNECTION SHOULD BE PROVIDED IN THE SITE ELECTRICAL GROUNDING PLANS.
