Battery Installation
WARNING!
Follow battery manufacturer’s safety recommendations when working around battery systems
and review the safety instructions provided in this manual.
Batteries must be rated at the same capacity, and must be equal in age and quality.
5.1
Preparation/Mounting
The Enclosure must be mounted (Section 4) before installation of the bottom tray of batteries may be completed.
Batteries should be located in a temperature-controlled environment. The temperature should be regulated at
approx. 25°C (77°F). Significantly lower temperatures reduce performance and higher temperatures decrease life
expectancy.
Before assembly, clean cells (where applicable) as per the battery manufacturer's recommendations. First
neutralize any acid with a baking soda and water solution. Then wipe the cells with clean water.
5.2
Installation of Batteries in Alpha Power Systems
CAUTION!
Verify that all battery breakers, DC circuit breakers, and fuses on the distribution panels are either
in the OFF position or removed. For each of the following steps, verify that the rubber terminal
caps / plastic covers are on and are completely covering the positive and negative terminal
connections.
Note: FMPS installed with two strings of Battery and if one is removed there is need of Field kit Part# 037-270-20 (2 to 1
“Y” battery bridging harness kit). For installation instructions refer to 075-212-10 document.
Use a corrosion-inhibiting agent, such as NO-OX-ID “A”
, on all battery terminal connections.
1.
Check the battery block voltage (typically >12.6V).
2.
Remove the battery pigtails from their plastic bag and connect them to the battery terminals as shown below:

–Connecting the battery pigtails
NOTE:
The FMPS can be initially equipped with one string of batteries. If a second string of batteries is added later, the
FMPS software will qualify the new battery string and begin periodic testing.
3.
Verify polarity and voltage at connectors.
4.
Loosen the battery retaining bracket thumbscrews and let the brackets fall clear of the battery shelves.
NOTE:
The FMPS passes GR63 flame testing using HB rated flame retardant 7.2AH batteries. Greater levels of fire
resistance can be achieved using 94V0 rated batteries.
The pigtails are manufactured
to prevent misconnection.
