4.1 Battery Module Installation
1. Transport battery modules to the installation location.
3. Place the battery modules on the bracket or rack or cabinet.
4. Fix the battery on the bracket or rack. Using the bracket or cabinet bolt to fix the battery into the
bracket or rack.
5. After installation, tighten all bolts.
Figure 4-1: Battery Module Installation (A possible battery install procedure)

-11-
▪We recommends installing battery modules in the upper shelves first and
proceeding to the bottom.
▪The battery can be mounted on a standard 19 inches cabinet or rack.
▪Battery modules can be inserted into a rack frame according to the
customer battery configuration scheme.
5. Cable Connection
5.1 Single Battery Connection
▪Before connect the cable with the inverter, the worker must confirm the output
switch of the inverter has been turn off, to prevent the risk of fire or electric
shock.
▪Before connection, make sure to close the battery.
▪Please follow the instructions to protect the module BMS against damage.
▪DO NOT deviate from the sequence of steps below.
▪Exercise extreme caution prevent the terminals from contacting anything except
their intended mounting points.
▪Terminals and their connected wires have either positive or negative polarity
(Positive: +; Negative-). The polarity of a terminal or a wire connected to the
terminal is onthe front of each module. Exercise extreme caution to prevent the
terminals and/or wires with opposite polarity from contacting with each other.
▪The maximum voltage of the battery is no more than 60V, which is higher than
the safe voltage of 36V. Therefore, we still recommendthat the battery terminals
or other exposed parts should not be directly touched during the installation.

-12-
▪When tightening the screws, make sure they are at a straight angle from the
battery module terminals to avoid damage to the nuts inside.
▪Assemble the screws using a Phillips-head within the fasteningtorque of less
than 8.0 Nm (79.88 kgf/cm).
▪The power terminals, such as “+,” “-,” of the module are covered with the
protecting cover to guard against a short circuit (Shown in Figure 5-1).
▪You must remove the insulation cover prior to connecting and reattach the
insulation cover immediately after connecting.

5.3 Visual Inspection of the Connection
After connecting the battery, check for:
 Usage of positive and negative cables.
 Connection of the positive and negative terminals.
 All the bolts are tightened.
 Cables fixation and the appearance.
 The setting of the dialing address.
 The installation of the protecting cover.
6. Activate the Product
6.1 Start the Battery
After installation, wiring, and configuration are completed, you must check all the connection. When
the connections are correctly, and then press power button to activate the battery. The green working
light on the front panel of the battery flashes, indicating that the battery system is normal.
7. Inspection, Cleaning and Maintenance
7.1 General Information
 The battery product is not fully charged. It is recommended that the installation be completed
within 3 months after arrival;
 During the maintenance process, do not re-install the battery in the battery product. Otherwise,
the performance of the battery will be reduced;
 It is forbidden to dismantle any battery in the battery product, and it is forbidden to dissect the
battery;
 After the battery product is over-discharged, it is recommended to charge the battery within 48
hours. The battery product can also be charged in parallel. After the battery product is
connected in parallel, the charger only needs to connect the output port of any product battery.
 Never attempt to open or dismantle the battery! The inside of the battery does not contain
serviceable parts.
 Disconnect the Li-Ion battery from all loads and charging devices before performing cleaning
and maintenance activities
 Place the enclosed protective caps over the terminals before cleaning and maintenance

-18-
activities to avoid the risk of contacting the terminals.
7.2 Inspection
 Inspect for loose and/or damaged wiring and contacts, cracks, deformations, leakage or
damage of any other kind. If damage to the battery is found, it must be replaced. Do not attempt
to charge or use a damaged battery. Do not touch the liquid from a ruptured battery.
 Regularly check the battery’s state of charge. Lithium Iron Phosphate batteries will slowly self-
discharge when not in use or whilst in storage.
 Consider replacing the battery with a new one if you note either of the following conditions:
- The battery run time drops below 80% of the original run time.
- The battery charge time increases significantly.
7.3 Cleaning
If necessary, clean the Li-Ion battery with a soft, dry cloth. Never use liquids, solvents, or abrasives
to clean the Li-Ion battery.
7.4 Maintenance
The Li-Ion battery is maintenance free. Charge the battery to approximately > 80% of its capacity at
least once every year to preserve the battery’s capacity.
7.5 Storage
 The battery product should be stored in a dry, cool and cool environment;
 Generally, the maximum storage period at room temperature is 6 months. When the battery is
stored over 6 months, it is recommended to check the battery voltage. If the voltage is higher
than 48V, it can continue to store the battery. In addition, it is needed to check the voltage at
least once a month until the voltage is lower than 48V. When the voltage of the battery is lower
than 48V, it must to be charged according to the charging strategy.
 The charging strategy is as follows: discharge the battery to the cutoff voltage with 0.2C10A
current, and then charge with 0.2C10A current for about 3 hours. Keep the SOC of the battery
at 40-70% when stored;
 When the battery product is stored, the source of ignition or high temperature should be avoided
and it should be kept away from explosive and flammable areas.
