Chapter 1 Inspection and Safety Precautions
4
Process
Type
Explanation
injury or damage to this unit!
Note
★
When the inverter is operating, you should avoid that
objects fall into this unit.Otherwise cause damage to this unit!
★
Do not start/stop the driver by switching on/off
contactor. Otherwise cause damage to this unit!
When
maintaining
Danger
★
Do not perform repairs and maintenance for the live
electrical equipment. Otherwise there is a risk of electric
shock!
★
The repairs and maintenance task can be performed only
when the inverter voltage is lower than AC36V,generally
that is two minutes after powering off. Otherwise, the
residual charge from capacitor would cause personal
injury!
★
Non-well-trained professional personnel is not allowed
to perform repairs and maintenance of inverter. Doing so
may cause personal injury or damage to this unit!
★
After replacing the inverter,parameter settings must be
redone, all pluggable plugs can be operated only in the
case of powering off!
1-3.Precautions
No.
Type
Explanation
1
Motor insulation
inspection
Please perform motor insulation inspection for the first time
use, re-use after leaving unused for a long time as well as
regular check, in order to prevent damage to the inverter
because of the motor's winding insulation failure. Wiring
between motor and inverter shall be disconnected, it is
recommended that the 500V voltage type megger should be
adopted and insulation resistance shall be not less than
5MΩ.
2
Motor thermal
protection
If the rated capacity of the selected motor does not match
the inverter, especially when the inverter rated power is
greater than the motor rated power,be sure to adjust the
motor protection parameter values inside inverter or install
thermal relay in the front of motor for motor protection.
3
Run over power
frequency
This inverter can provide (0Hz to 400Hz
）
output
frequency If the user is required to run at 50Hz or more,
please consider the endurance of your mechanical devices.
4
Vibrations of
mechanical device
Inverter output frequency may be encountered mechanical
resonance point of the load device, you can set jump
frequency parameter inside inverter to avoid the case.
