2.6.2 Battery Installation Procedure
1. Place the batteries, with the terminals oriented toward the front of the enclosure on
the battery shelf (see Fig. 2-15). Use the battery manufacturers’ recommended
spacing between batteries for maximum ventilation space.
2. For ease of identification and future record keeping, number batteries using labels
or masking tape. Record each battery's number and date code in the power supply
maintenance log
3. Connect the batteries in series to achieve 36VDC. You must install the battery-
mounted fuse in either single or dual 36VDC series (see Fig. 2-15).
Verify battery polarity and install battery jumper bars after attaching all terminals to respective terminal posts
4. Use a voltmeter to verify polarity and DC voltage at the module’s battery connector.
5. The power supply battery charger utilizes a Remote Temperature Sensor (RTS) to
provide precise battery temperature compensation information. Using high strength
tape, attach the sensor to the center of the middle battery about 2/3 of the way up
from the base of the battery. Route the RTS connector into the power supply
compartment. DO NOT connect the RTS to the power supply at this time.
6. Route the battery cable connecter into the power supply compartment.
The cables are marked with a RED sleeve to indicate the (+) positive battery terminal.
The In-line Fuse is required for single or dual battery string installation. See Fig. 2-14.
