7 ID Switch
 ID Switch indicates the unique ID code for each battery module. It's required to assign a unique ID to each
battery module for normal operation.
 We can set up the ID code for each battery module by rotating the PIN number on the ID switch. From
number 0 to 9, the number can be random; no particular order.
 If more than one battery module in the parallel system, the battery pack connected to the inverter module is
the Master battery and the ID code should be set as 0. The ID code of the remaining battery module MUST
be unique. Do not set the same number for 2 battery modules in the parallel system.
 Maximum 10 battery modules can be operated in parallel.

3. Installation
3.1 Installation Environment
Make sure that the installation environment meets the following conditions:
 The area is completely waterproof.
 The floor is flat and level.
 There are no flammable or explosive materials nearby.
 The ambient temperature is within the range of 0~50°C.
 The temperature and humidity are maintained at a constant level.
 There is minimal dust and dirt in the area.
Caution:
If the ambient temperature is out of the operating range, the battery module will stop operate to protect itself. The
optimal temperature range for the battery module to operate is 0°C to 50°C. Frequent exposure to harsh temperatures
may deteriorate the performance and shorten the life cycle of the battery module.

3.2 Mounting the Modules
Step 1: Clip two SNAP bushings into the stand feet. Then, fix two fixing plates on the stand feed (both sides) with eight
screws. finally, fix two L-type brackets on the battery module (both sides) with four screws.
Step 2: Install one battery module by following below steps.
(a) Use a Ø13mm drill to drill holes about 60mm deep according to the distance indicated on the below chart. Drill
two holes on the floor first, then drill two holes on the wall. If there is one more battery module to be stacked up,
drill two holes at a vertical distance of 420mm.
(b) Push four expansion bolts into the Ø13mm holes drilled on the previous step.
(c) Remove nut, spring washer and flat washer.

(d) Take assembled battery module (in step 1) and put on the ground. Align the hole on fixing plate with the two expansion bolts
on the ground. Align the hole on L-type bracket with two expansion bolts on the wall. Pass through the remaining bolt in the
floor and wall. Then, screw back the nut, spring washer, and flat washer
Step 3 (If more than one battery module is connected):
For a single battery module connection, please skip this step! If more than one battery module is connected, please
follow the instructions below:
(a) Put the additional battery module on the top of battery module installed on the ground. Make sure they are
aligned well.
(b) Install one fixing plate to fix two battery
modules with four screws as following the
picture shown.

(d)
(e) Refer to Step 2, fix the top battery module on the wall with two expansion bolts.
(f) If there are more battery modules installed, repeat steps (a) to (d).
Step 4 (If an optional PDU module is required in the system): Stack the PDU module on the top of all battery
modules. Install two fixing plates (supplied in PDU module package) on both sides of the modules with eight screws.
3.3 Wiring Configuration
Step 1: Insert the supplied RJ11 jumper into one of the extension port on the top of the battery
module.
*It's required to connect to the battery module for normal operation.
Step 2 (If multiple battery modules are in parallel): Insert RJ11 cable to connect the extension port of the
master battery module*. The other end connects to the extension port of the #2 battery module. If there are more
