Procedure:
1. Place the batteries on the enclosure’s battery slide tray or battery shelf. Refer to Fig. 2-16 for correct battery
arrangement. 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, connect the batteries in series to achieve 36Vdc. 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) or Precision Temperature Sensor (PTS). Refer to the diagrams and follow the
instructions below that best matches your configuration:
• XM3 – Attach the PTS on the negative terminal of the #2 battery string.
• XM2-300HP – Attach the DRTS (Dual Remote Temperature Probe) to the negative terminal of the battery.
• XM2 – Attach the RTS about 1/3 of the way up from the battery’s base with a strong adhesive tape. Route the
RTS connector into the power supply compartment.
6. After attaching the sensor to the battery, DO NOT connect the RTS/PTS to the power supply at this time.
7. Route the battery cable connector into the power supply compartment. DO NOT connect to the batteries to the
power supply at this time.
2.0 Installation, continued
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! ELECTRICAL HAZARD
In battery configurations made up of multiple battery strings, Alpha strongly recommends the use of in-line fuses.
NOTICE:
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!
!
Recheck the polarity and voltage of the battery cable connector before proceeding. Connecting the battery string or
strings to the power supply with incorrect polarity will cause a short-circuit, and possible equipment damage.
CAUTION!
