Chapter 1 Safety Requirement and Cautions
To ensure safety of your health, equipment and property, please read this chapter carefully before
using solar pump inverter and act in compliance with the instructions when installing,ebugging,
running and overhauling solar pump inverter.
1.1 Safety Definition
● Installation
1. Only qualified personnel can operate the equipment. Before operating, be sure to carefully
read the manual about safety, installation, operation and maintenance. The safe operation
depends on the proper processes of choosing models, carrying, installation, operation and
maintenance.
2. Please install solar pump inverter on metal or other nonflammable material, and keep it away
from the combustible material. Otherwise there is danger of fire;
●Wiring
Danger
1. Wire is connected only when the main circuit is cut off, otherwise there is a danger of shock.
2. Wire is connected by professional person only. Otherwise there is a danger of shock.
3. Earth must be reliable. Otherwise there is a danger of shock.
4. AC power supply should not be connected with output ports U, V, W, otherwise there is a
danger of damage to frequency inverter.
5. No drop of bolt, spacer, metal stick, conducting wire or other things into the inner of frequency
inverter; Otherwise there is a danger of fire or damage to frequency inverter.
●Electrification
Danger
1. Please make sure that voltage grade of power supply is consistent with frequency inverter's
voltage and then check whether the wiring is correct and firm, and whether there is short
circuit in peripheral equipment's circuit. Otherwise it will damage frequency inverter and other
equipment.
2. Before solar pump inverter is connected to the input power supply, make sure that the cover
