When the alarm code appears, the battery is still in normal working mode. When the elements
triggering the alarm are removed, the battery will automatically resume working.
In the working mode, if the alarm code 09 appears, the power button can be pressed 5 times within
10 seconds, and the BMS will force the MOS to close. At this time, the inverter can detect the battery
and charge the battery.

2.4.3 Installation and Wiring
The following actions should be carried out before wiring:
1. Ensure that the power button of all batteries is OFF;
2. Cut off all relevant power supply. Step 2: As shown in Figure 4, put the battery into the cabinet, tighten the four-angle screws
(M6*12 cross head triad screw, torque: 5 N.m); and fix the copper strip between the battery
modules with 3#cross screwdriver (M8; torque: 12 N.m).
Step 1: As shown in Figure 3, fix the hanging ear on both sides of the battery with 4 internal
Torx flat cup screws respectively.(Torque: 1.6 N.m; Tools: T20 internal torx screwdriver ).
1、Serial connection between batteries is not allowed；
2、The power line of the cross-sectional areaconnected to the inverter should be at least 35
mm2（About AWG 2), and temperature resistance ≥105°, pressure resistance (DC) ≥500V.

（Accessories need to be purchased separately）
The sequence is specific to the Voltronic inverters only.
Step 1: As shown in Figure 7, place the battery on the base and tighten limit brackets located at
the four corners (screw: M4*10 outer hexagonal and internal torx combination screw; torque: 1.6
N.m; 10pcs in total )
Step 2: As shown in Figure 7, stack the second battery neatly on the first one and tighten the
limit brackets with a T20 screwdriver(screw: M4*10 external hexagonal box Combination screw ;
torque requirement: 1.6 N.m; 10pcs ).
Step3: Refer to Step 2 and stack the battery in turn, as shown in Figure 9。
As shown in figure 5, connect the communication cable, and dial code after connection. Switch '2'
and '4' for the top battery. Switch '1','2' and ‘4’ for the bottom battery,and '4' for all other batteries.
Note
DIP Switch of battery should be set as below
Only one Bat: More than two Bats:
PS: The top battery communicates with the inverter
The communication wiring between the battery and the inverter has a special sequence.The
requirements of communication wiring connection are shown in Figure 6.
Note
A bracket (including a left bracket and a right bracket) is used for each 2 batteries

4.2.1 Unable to Turn on
Check all power cables and communication cables carefully.
Common faults and corresponding troubleshooting are listed below.
START: Switch off the Battery Breaker, press the Power Switch (Rebound button) to "ON" for 1-2
seconds. Then the battery module will activate and the LED display will light up.
CLOSE: Press the Power Switch (Rebound button) to "ON" for 5 seconds, and the bat-tery will be
turned off.
Batteries should be turned on in the correct order to avoid damage
• Check if the environment situation the requirements of the battery.
• Check whether the charging and discharging function of the battery is normal. When one of the
following situations happen, it is necessary to charge the battery in time: the battery alarm code
09 appears, the battery is often under charged, and the battery is stored for more than 3 months.
• Check the battery and its appearance, terminals, cables, LED lights, etc.
Fault Troubleshooting Description
Press the Power switch
to "ON" for 2 seconds
and then let go. The
LED is not light up
within 3 seconds.
