3.0 Installation, continued
Tools Needed:
7/16” open end wrench
Torque wrench
Procedure:
This section is for reference only, follow instructions included in the battery cable kit. This procedure covers the UPE-M3
(one tray), and the UPE-M6 and UPE-M8 (two trays).
Fig. 3-11, UPE-M3 Battery Wiring Diagram (for use with slide tray)
1. Release the latch on the left slide. Pull the (lower) tray out until it reaches the stops.
2. Place the batteries on the enclosure’s battery slide tray or battery shelf. The correct arrangement of the batteries on
the tray or shelves varies between enclosure models. See Figs. 3-11 and 3-12 for the correct battery arrangement.
Leave a minimum of one inch of ventilation space between the batteries.
3. 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.
4. Using the battery arrangement diagrams as a reference, connect the batteries in series to achieve 36VDC or 48VDC .
Refer to the diagrams for the location of the optional in-line fuses. For AlphaCell batteries, torque terminal connections
to approximately 65 in-lbs (7.3 Nm) at installation and re-torque to 50 in-lbs (5.6 Nm) during routine maintenance. For
non-Alpha batteries, torque to manufacturer’s specifications.
5. Verify the batteries are properly connected by checking the polarity and voltage of the battery cable connector with a
digital voltage meter. DO NOT connect the battery string or strings to the power supply at this time.
6. 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 Fig. 3-11 or Fig. 3-12 to determine the RTS attachment
point. See Section 3.1 for RTS the attachment procedure.
7. Route the battery cable connector into the power supply compartment. DO NOT connect to the batteries to the power
supply at this time.
8. Disengage the hold-open latch and slide the battery tray into the enclosure.
9. Repeat for the center tray (UPE-M6 and UPE-M8 only).
