The ground fault circuit interrupter must be a high-speed type
breaker of 30 mA (<0.1 s).
NOTE
Stated values are maximum values (see electrical data for exact values).

、
The parallel function of the system only supports 6 machines at most .
2
、
In order to ensure the success of automatic addressing, all machines must be connected to the same power
supply and powered on uniformly.
3
、
Only the Master unit can connect the controller, and you must put the SW9 to “on” of the master unit, the slave unit
cannot connect the controller .
4
、
Please use the shielded wire, and the shield layer must be grounded.

Port provide the control signal to the load.Two kind of control signal port:
Type 1
：
Dry connector without voltage.
Type 2
：
Port provide the signal with 220V voltage. If the current of load is <0.2A, load can connect to the port directly.
If the current of load is ≥0.2A, the AC contactor is required to connected for the load.
Control signal port of hydraulic model contains terminals for solar energy, remote alarm, 3-way valve, pump,and external heating
source, etc.
