Chapter 1 Safety and Precautions
-7-
1.1.6 During the operation:
Danger Danger
1. Do not approach the mechanical
equipment when selecting the restart
function.
Otherwise it may cause injury!
2. Do not touch the heatsink fan or
discharge resistor to sense the
temperature. Otherwise, you may get
burnt!
3. Detection of signals during the
operation shall only be conducted by
qualified technician. Otherwise, personal
injury or equipment damage may be
caused!
NoteNote
4. During the operation of the inverter,
keep items from falling into the
equipment. Otherwise, it may damage
the equipment!
5. Do not start and shut down the
inverter by connecting and
disconnecting the contactor.
Otherwise, it may damage the
equipment!
1.1.7 Maintenance
Danger Danger
1. Do not repair and maintain the
equipment with power connection.
Otherwise there will be danger of
electric shock!
2. Conduct repair and maintenance
after ensuring that the charge LED
indictor of the inverter is OFF.
Otherwise, the residual charge on the
capacitor may cause personal injury!
3. The repair and maintenance for
inverter can only be performed by
professional technicians.
Otherwise, it may cause personal
injury or equipment damage!
1.2 Precautions
1.2.1 Motor Insulation Inspection
When the motor is used for the first time,
or when the motor is reused since the
previous use, or when periodical inspection is
performed, the motor insulation inspection
shall be performed so as to avoid damaging of
the inverter due to the insulation failure of the
motor windings. The motor wires must be
disconnected from the inverter during the
insulation inspection. It is recommended to
use the 500V megameter, and the insulating
resistance measured shall be at least 5Mȍ.
1.2.2 Thermal Protection of the Motor
If the ratings of the motor do not match
those of the inverter, especially when the
rated power of the inverter is higher than the
rated power of the motor, the relevant motor
protection parameters in the inverter shall be
adjusted, or thermal relay shall be mounted to
protect the motor.
1.2.3 Running with Frequency higher than
Standard Frequency
This inverter can provide output
frequency of 0Hz to 300Hz. If the user needs
to run the inverter with frequency of more than
50Hz, please take the resistant pressure of
