2.6.2 Battery Assembly for Vertical Terminal Battery Posts
This is the typical battery terminal assembly for vertically mounted battery posts.
Refer to the battery manufacturers' specifications for tightening torque.

2.6.3 Installation Procedure
NOTE:
The cables have a red sleeve to denote the (+) positive battery terminal. When using multiple battery strings,
the in-line fuse is recommended.
Place the batteries, with the positive terminals oriented toward the front of the 1.
enclosure, on the battery slide tray or shelf. Maintain as much ventilation space
between batteries as possible.
Number each battery and record the number and date code in the maintenance
2.
log. This aids in indentification and future record keeping.
Connect the batteries in series to achieve the correct voltage. See the battery
3.
wiring diagrams on page 22. If you are using the optional in-line fuse, connect it
to the positive terminal of the battery located farthest to the right. For AlphaCell
batteries, terminal connectors must be torqued to approximately 65 inch/pounds
at installation and then re-torqued to 50 inch/pounds during routine maintenance.
Use a voltmeter to verify polarity and DC voltage at the module's battery
4.
connector.
Plug the battery cable connector into the battery cable connector from the conduit
5.
kit.
CAUTION!
Do not let live battery cables contact the chassis when you are making or breaking battery
connections. If necessary, wrap the lugs with electrical tape to prevent arcing and temporarily
disconnect one of the leads from the center battery. Ensure the battery string voltage and polarity
are correct.
