danger of electric shock.
3. Do not operate or touch frequency VFD with wet hand. Otherwise there is danger of damage to frequency
VFD and electric shock.
Attention
1. Please set the parameter of frequency VFD cautiously; Otherwise it will damage equipment.
● Operation
Danger
1. Before running, please check and confirm the application range of the machine and equipment once more;
Otherwise it will cause accidents.
2. Please don't touch the cooling fan and braking resistance to check the temperature; Otherwise there is a danger
of getting burn.
3. Unprofessional workers are banned to check the signals in the running stage; Otherwise it will cause injuries
and damage the equipment.
Attention
1. Please don't turn off the equipment by switching off power; Please cut off the power supply after the electric
machine stops running; Otherwise it will damage the frequency VFD.
2. Please avoid anything dropping into the equipment when the frequency VFD is running; Otherwise it will
cause electric shock.
● Maintenance
Danger
1. Please don't maintain and repair the equipment with electric; Otherwise it will cause electric shock.
2. Before maintaining and repairing the frequency VFD, please make sure the indicator lights of power supply
have completely turned off; Otherwise it may cause electric shock and damage the frequency VFD.
3. Persons who have not passed specialized train are not allowed to conduct the frequency VFD maintenance;
Otherwise it may cause electric shock and damage the frequency VFD.
1.3 Cautions in Using
1. In application of this series frequency VFD, you have to confirm all machine insulation to prevent damage to
the equipment. Moreover, when the motor working in tough environment, please periodic inspect the electrical
insulation to ensure the safety of the system work.
2. If the motor adapter is not consistent with frequency VFD's rating current (The rating current of the motor is
far smaller than that of frequency VFD), please adjust the protective value to ensure safe running.
3. In occasions such as load raises, usually there is negative torque and frequency VFD breaks off for
over-current or over-voltage. In this case, you should consider choosing the matching brake unit.
4. Frequency VFD, in a certain output frequency range, can meet the mechanical resonance of the load
