5.3 Pre Installation Rack/Enclosure Location Check

Floor bearing: Since batteries are heavy, check the floor loading is not exceeded. Check

rack/enclosure complies with any load spread requirement, and seismic zone

requirements of the installationarea.

To assemble a Leoch battery rack/enclosure, see rack installationinstructions.

5.4 Battery Installation and connection



Use insulated tools only;

Connect battery modules together to the required system voltage, then connect battery string with

charger or load;



When multi-strings of batteries are to be parallel connected, connect batteries in series first & then

complete the parallel connection. Parallel cables to the charge/load should be as close in sizeand

length from each of the parallel strings to prevent uneven voltage drops that can imbalance the

parallel battery strings.



To ensure good ventilation, the batteries per row should keep around 0.4” to .79” (10 - 20mm) inter-

bloc spacing;

A good rule of thumb on the proper cable sizing between batteries:

a) AWG# 6 for loads up to 90 Amps.

b) AWG# 2 for loads up to 150 Amps.

c) AWG# 1/0 for loads up to 250 Amps.

d) AWG# 4/0 for loads up to 400 Amps.

e) Refer to NEC for voltage drops for long cables.



Before connection, lightly clean the battery terminals to remove sulfate and dirt.

Before connecting inter-cell connectors apply a light coating of No-Ox grease to the surface of the

terminal and inter-cell connectors or cable lugs;



After batteries are installed, test the voltage of the battery string. Make sure there are no battery

modules that have been incorrectly installed in reverse polarity. If all modules installed correctly,

link battery to load.

Use correct torque on all terminals, ensuring every connecting nut and screw is secure; see torque

settings as table 1 below.
