5.3 Pre Installation Rack/Enclosure Location Check
Floor loading : Since batteries are heavy, check th e floor loading is not exceeded. Check rack /
enclosure complies with any load spreading, and seismic zone requirements of the installed area.
To assemble a battery rack/enclosure, please see rack installation instructions.
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
and then complete the parallel connection. Parallel cables to the charger / load should be as close
in size and length to 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 kep t around 0.4” to .79” (10 - 20mm) inter-bloc
spacing;
A n estimated open air rating on the proper cable sizing between batteries:
1) AWG# 6 for loads up to 90 Amps.
2) AWG# 2 for loads up to 150 Amps.
3) AWG# 1/0 for loads up to 250 Amps.
4) AWG# 4/0 for loads up to 400 Amps.
5) Refer to NEC for voltage drops for long cables.
1. Before connection, lightly clean the battery terminals to remove sulfate and dirt.
2. 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;
3. 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.
4. Use correct torque on all terminals, ensuring every connecting nut and screw is secure; see
torque
settings as table 1 below.
