location.
The local controller with protection degree IP20 can only be installed
indoors.
The ambient temperature range is -30℃to +60℃.
The humidity cannot exceed 95%. Otherwise, internal components can be
damaged.
Take proper damp-proof and anti-corrosion measures.
5.3 Installation
The local controller can be installed at any indoor locations provided that the
requirements above are met.
5.3.1 Rack Mounting
In the rack mounting manner, the standard 1U rack is used, and installation
steps are as follows:
Step 1The distance between the two hangers of the local controller is shown in
the following figure.

High voltage on the AC power supply port! Do not operate under
voltage. Make sure the input side is completely voltage-free and the
grounding cable is reliably grounded before cable connection.
SD card does not support hot plugging.
6.3 Communication Device Connection
Devices that can be connected to the local controller include PCS, BCP, and the
like.
6.3.1 COM Port Connection
Devices are connected to serial ports of the local controller in the daisy chain
manner by using the RS485 bus.
The RS485 communication cable must be shielded twisted pair cable
and single-point grounded.
0.2mm²≤the maximum cross-sectional area of the shielded twisted
pair ≤1.2mm², and the recommended stripped length of the cable is
8mm.
Keep at least 0.5m away from the strong electricity. Avoid parallel cable
layout. Use the steel tube in area with strong interference.
It is recommended to add an SPD if an outdoor device is connected to
the local controller. Otherwise, the local controller may be damaged by
lightning.
The local controller supports a maximum of 6 RS485 buses. COM1
to COM 5 support connections to optional devices as well as PCS,
battery BMS (BMS of Samsung battery only). COM6 is used to
connect touch screen and other devices.
When more than 15 devices are connected to the RS485 bus, it is
recommended to connect 12Ωresistors in parallel to A and B of the
devices on two ends of the bus.
