Chapter 1 Inspection and safety precautions
4
Process Type Explanation
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 5M
Ω .
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.
5
Motor heat and
noise
The inverter output voltage is PWM wave that contains a
certain amount of harmonics, so the temperature rise,noise
and vibration of motor show a slight higher than frequency
power frequency operation.

No. Type Explanation
6
Output side with
piezoresistor or
capacitor for
improving power
factor The inverter output is PWM wave, if the piezoresistor for
lightning protection or the capacitor for improving power
factor is installed in the output side, which easily cause the
inverter instantaneous overcurrent or even cause damage
to the inverter. Please do not use.
7
Contactor or
switch used in the
inverter
input/output
terminals
If contactor is installed between power supply and
inverter,the contactor is not allowed to start/stop the
inverter. Necessarily need to use the contactor to control
the inverter start/stop, the interval should not be less than
one hour. Frequent charging and discharging may reduce
the service life of the inverter capacitor. If the contactor or
switch is equipped between output terminals and motor,
the inverter should be turned on/off without output status,
otherwise which easily lead to damage to the inverter
module.
8
Use other than the
rated voltage
CA Series inverter is not suitable for use beyond the
allowable operating voltage described in this
manual,which easily cause damage to the parts inside
inverter. If necessary, please use the corresponding
transformer to change voltage.
9
Never change 3-
phase input to 2-
phase input Never change CA Series 3-phase inverter to 2-phase one
for application. Otherwise it will lead to malfunction or
damage to the inverter.
10
Lightning surge
protection
The series inverter is equipped with lightning overcurrent
protection device, so it has the ability of self-protection to
lightning induction. For the area where lightning is
frequent, user should also install the extra protection in the
front of the inverter.
11
High altitude and
derating
application
When the inverter is used in areas over 1000m altitude,it is
required to reduce frequency because the thin air will
decrease the cooling effect of inverter. Please consult our
technician for details on the application.
12 Special use
If the user need to use methods other than the suggested
wiring diagram provided in this manual, such as common
DC bus, please consult our technician.
13
Precautions for
scrap disposal of
the inverter
It may explode when electrolytic capacitors on the main
circuit and printed circuit board are burned. When burning
plastic parts, it may produce toxic gases.Please disposing as
industrial waste.
14
About
adaptive motor
1) Standard adaptive motor shall be four-pole
asynchronous squirrel-cage induction motor. Apart
from the said motors, please select the inverter
according to the motor rated current.
2) The cooling fan and the rotor shaft for non-inverter
motor are coaxially connected, the fan cooling effect is
reduced when the rotational speed is reduced, therefore,
