5 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 Argus 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.

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:

Figure 10–Connecting the battery pigtails

The pigtails are manufactured

to prevent misconnection.

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.
