Battery Installation, continued
Procedure:
1. Place the batteries on the enclosure’s battery shelf. Position the batteries to allow
maximum ventilation space between the batteries.
2. To make identification and record keeping easier, number and label the batteries. Record
each battery’s number and date code in the power supply maintenance log.
3. Using the battery arrangement diagram as a reference, achieve 12Vdc. Torque terminal
connections according to battery recommendations (see battery label for AlphaCell
batteries).
4. Check the polarity and voltage of the battery cable connector with a voltmeter to verify
correct connections. Do Not connect the battery string or strings to the power supply at this
time.
5. The power supply battery charger collects battery temperature compensation information
with a Remote Temperature Sensor (RTS) attached to one of the batteries. Refer to the
diagrams to determine which battery to attach the RTS to. Co-term the RTS onto the
negative battery terminal. Route the RTS connector onto the power supply shelf and
attach to provided cable clip. Do Not connect the RTS to the power supply at this time.
6. Route the battery cable connector into the power supply compartment. Do Not connect to
the batteries to the power supply at this time.
In battery configurations made up of multiple battery strings, Alpha strongly recommends the use of in-line
fuses.
NOTE:
Threaded insert terminals require the use of 3/4" bolts. The use of 1" bolts will seriously damage the
battery. The only exception is the terminal with the large spacer for the in-line fuse link.
CAUTION!
To prevent arcing, never allow live battery cables to make contact with the enclosure.
Disconnect battery leads, or wrap the cable lugs with electrical tape.
WARNING!
Recheck the polarity and voltage of the battery cable connector before proceeding.
CAUTION!
