Battery Terminal Assembly Procedure
These illustrations show the Battery Terminal assembly for vertically mounted battery posts. Refer to the battery
manufacturers’ specifications for tightening torque.

Battery Installation Procedure
1.
Place the batteries on their respective shelves as shown in Figure 3-18; "Battery Installation Arrangement"
on the next page.
2.
Connect the three (or four) batteries in series (negative to positive) to achieve 36VDC (or 48VDC). Route
the battery cables inside the vertical rail for connection to the power supply. Terminal connectors must
be torqued to approximately 75 inch/pounds at installation and then re-torqued to 50 inch/pounds
during routine maintenance.
NOTE:
The cables are marked with a RED sleeve to indicate the (+) positive battery terminal.
3.
Use a voltmeter to verify polarity and DC voltage at the module's battery connector.
CAUTION:
Whenever making or breaking battery connections, never allow live battery cables to
contact the chassis. If necessary, wrap the lugs with electrical tape to prevent arcing
and temporarily disconnect one of the leads from the center battery. Check the battery
voltages at the connectors leading into the XM power supply.
NOTE:
Ensure that voltage and polarity are correct before proceeding.
4.
Mate the battery connectors to their respective sockets on the power supply module.
5.
Number the batteries 1, 2, 3, (4) using labels, masking tape, or china marker. Record each battery's
number and date code in the power supply's maintenance log.
6.
For installations with multiple battery strings in parallel, each string must be fused. Verify that the
enclosure was ordered with a fused Battery Cable Kit (BCK). For replacement fuses, or to add fuses to
a BCK without fuses, order the Battery Terminal Fuse Kit, Alpha part number SPB98-645-1.
