Chapter 1 Safety Requirement and Cautions

To ensure safety of your health, equipment and property, please read this chapter carefully before using the frequency inverter
and act in compliance with the instructions when installing,ebugging, running and overhauling the frequency inverter.
1.1 Safety Definition
Danger: it will cause danger of serious injuries and even death while operating against the rules.
Caution: it will cause danger of light injuries or equipment destruction while operating against the rules.
Note: some information is useful while operating and use frequency inverter.
1.2 Safety Requirements and Cautions
●Before 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.
1. Don't use the damaged or incomplete frequency inverters; Otherwise, there is risk of injury.
●Installation
1. Please install the frequency inverter on metal or other nonflammable material, and keep it away from the combustible
material. Otherwise there is danger of fire;
2. No unauthorized modification to the frequency inverter; Otherwise there is danger of damaged.
3. Normal frequency inverter, which is not explosion-proof, can not be installed where with explosive gas or dust; Otherwise
there is danger of explosion.
1. When two frequency inverters are installed in the same control cabinet, pleas pay attention to the installing place to
guarantee the effective heat dissipation.
2. When carrying the frequency inverter, ease support its bottom.
●Wiring
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
