5. Installation of batteries
5.1 Unpack and Check
Check the packaging for signs of shipping damage.
Unpack and check the appearance of battery for signs of damage or unidentified fluid.
Check parts list ensuring all accessories are included.
Read through the operation guide before handling the battery.
Handle the battery with caution:
Avoid any impact or force on the battery terminals!
Avoid any impact to the battery!
Do not tamper with battery seals!
Do not place the battery upside down!
Do not short circuit the battery!
5.2 Inspection Before Installation
If no shipping damage after checking, install the batteries in the designated position;
When installing batteries in a cabinet or on a rack, start at bottom & finish with placement at the top.
DO NOT install batteries near any potential heat source such as heat exhaust of other
equipment; Batteries may release flammable gas during charge or discharge operation. Batteries
must kept away from any possible source of flames or sparks.
Before connecting inter-cell connectors, lightly clean post terminals with non-metallic brush to
remove any sulfate or dirt from the terminal. Brush gently and do NOT damage the tin plating on
terminal, connector, or lugs.
Avoid any conductive materials shorting positive and negative terminals.
All installation tools must be insulated to prevent accidental arc flash.
Do NOT lubricate rack rails or bottom of battery jar as some lubricating compounds may cause
deterioration of the plastic battery container.
Do NOT clean battery jars with detergent, petroleum-based solvents or solutions with any
ammonia to clean the battery containers, these materials may cause permanent damage to the
battery container. Physical damage such as these are not covered under warranty.

5.3 Pre Installation Rack/Enclosure Location Check
Floor loading: Since batteries are heavy, check the 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 kept around 0.4” to .79” (10 - 20mm) inter-bloc
spacing;
An 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.
