5. Driver wiring instructions
Compressor TSC2-M028Y4 must be driven by a matched driver. The driver interface is shown
in the figure below.
5.1 Power input port（TB1, TB2）
The driver input voltage range is 24V±10%, port TB1 is positive and TB2 is negative.
5.2 Wiring port of driver and compressor（TB3, TB4, TB5）

The driver and the compressor are connected by a dedicated three-core cable, the colors of the
three-core cables are black, red, and white. The black wire is connected to port TB3; the red wire is
connected to port TB4; the white wire is connected to port TB5. The other end of the three-core wire
has been connected to the terminal block. The terminal block is buckled on the 3 terminal posts on
the top of the compressor without distinguishing the position.
5.3 Condensing fan power supply port（TB6, TB7）
The driver is equipped with ports TB6 and TB7 dedicated to supply power to the condensing fan,
where TB6 is the negative pole and TB7 is the positive pole. This port has voltage output only when
the compressor is running, the output voltage is 24V, and the maximum load is 2A.
5.4 Indicator
There are two indicators on the driver, the green one is the power indicator, and the red one is
the status indicator. The power indicator indicates the power status of the driver, and it will light up
as long as the power is connected. The status indicator indicates the compressor's working or fault
status. The specific description is shown in the table below.
Working/fault status
Description
Status indicator lighting
Normal work
No light
Waiting to start
The driver is connected to power, but the compressor does
not start.
Flashing at a constant
speed
Driver overvoltage
The high voltage protection is triggered when the input
voltage of the driver is higher than 32V, and returns to
normal when the voltage drops to 31.5V.
2 flash repeating
Driver undervoltage
When the driver input voltage is lower than 19V, the
low-voltage protection is triggered, and it returns to
normal when the voltage rises to 20.5V.
3 flash repeating
Driver overheating
The overheating protection is triggered when the
temperature of the driver exceeds 80 °C, and returns to
normal when the temperature drops to about 71°C.
4 flash repeating
Driver failure
The internal circuit of the drive is faulty.
6/7/8 flash repeating
External fault
Such as compressor stall, phase line short circuit, etc.
Light is always on

The status of the power indicator and the status indicator can be synchronously output through
ports TB13 and TB12, respectively.
5.5 5V voltage output port (TB8)
When the driver is connected to the power supply, the port TB8 can output a voltage of 5V,
which can be used to adjust the compressor speed, which will be described in detail later.
5.6 Compressor speed signal input port (TB9)
TB9 is a signal input port for controlling the speed of the compressor, which can receive voltage
signals, and the range is 0~5V (relative to GND). The corresponding relationship between voltage
value and compressor speed is shown in the following table (there may be some individual
differences).

5.7 Compressor enable signal input port (TB10)
The compressor can be started only when the compressor enable signal input port TB10 is
grounded (TB11). When TB10 is connected to high level or suspended, the compressor does not
work.
5.8 GND（TB11）
TB11 is connected to the negative port TB2 of the power supply, and is mainly used to connect
the control signal of the compressor. All voltage signals on the driver are relative to GND. If an
external circuit is used to control the compressor, the external circuit must also share the ground with
the driver.
5.9 Status signal output port (TB12)
