4.5 Battery Installation
This information is provided as a guideline and is not meant to imply that batteries are part of this power system.
WARNING
Follow battery manufacturer’s safety recommendations when working around battery systems
and review the safety instructions provided in this manual.
4.5.1 Preparation/Mounting
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.
Provide adequate ventilation. VRLA batteries, though not requiring the special ventilation requirements of a
flooded battery, should not be installed in an airtight enclosure. Hydrogen gas may be vented in a fault condition;
i.e., failed battery.
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.
4.5.2 Installation of Batteries
Verify that all battery breakers, DC circuit breakers, and fuses on the distribution panels are either
in the OFF position or removed.
Use a corrosion-inhibiting agent, such as NO-OX-ID “A”
™, on all battery terminal connections.
1. Assemble battery rack (if required) and the cells or mono-blocks as per the
installation instructions supplied with the batteries.
2. Ensure that the battery output cabling will reach the [+] and [–] terminals of the series
battery string and that the batteries are oriented correctly for easy installation of the
inter-unit “series” connectors.
3. Remove any NO-OX-ID “A”
™ grease from battery terminals.
4. Burnish terminal posts with a non-metallic brush, polishing pad or 3M Scotch Brite
™
scouring pad.
5. Apply a light coating of NO-OX-ID “A”
™ grease to the terminal posts.
6. If lead plated inter-unit connectors are used, they should also be burnished and NO-
OX-ID “A”
™ grease applied as above. Install the inter-unit connectors.
7. After all battery connections are completed, torque per battery specifications
(typically 100 in-lbs).
NOTE: See system startup procedure before connecting batteries online.
