！
Different types of inverters have clear requirements on AC power supply
voltage, frequency and power supply mode, etc. For specific requirements,
please refer to the corresponding technical parameters table of each type of
inverters in the appendix. It is strictly prohibited to connect power supply
sources that do not meet the requirements to the inverter, otherwise the
following consequences may occur:
● The inverter is not recoverable damage.
● The operation of the machine is unstable, manifested as unstable pipeline
water flow, pump running noise, etc.
9.5 Inverter grounding
Make sure the reliable connection between ground
terminal of Inverter
and the earth!
9.6 Water Level Sensor Connection
Dry protection function:
There are two kinds of detection models, automatic
and manual. Automatic
dry protection is achieved through inverter’s software.
And manual model need water level sensors to input signal through SENSOR
inside Inverter.
Overflow Protection:
water level sensors are requested to input signal
through SENSOR inside Inverter.
