by qualied personnel. Failure to comply will result in personal
injury or damage to the AC drive.
•Do not repair or maintain the AC drive at power-on. Failure to
comply will result in electric shock.
•Repair or maintain the AC drive only ten minutes after the AC
drive is powered off. This allows for the residual voltage in the
capacitor to discharge to a safe value. Failure to comply will
result in personal injury.
•Ensure that the AC drive is disconnected from all power supplies
before starting repair or maintenance on the AC drive.
•Set and check the parameters again after the AC drive is
replaced.
•All the pluggable components must be plugged or removed only
after power-off.
•The rotating motor generally feeds back power to the AC drive.
As a result, the AC drive is still charged even if the motor
stops, and the power supply is cut off. Thus ensure that the AC
drive is disconnected from the motor before starting repair or
maintenance on the AC drive.
1.2 General Precautions
1) Requirement on residual current device (RCD)
The AC drive generates high leakage current during running, which ows through the
protective earthing (PE) conductor. Thus install a type-B RCD at primary side of the
power supply. When selecting the RCD, you should consider the transient and steady-
state leakage current to ground that may be generated at startup and during running of
the AC drive. You can select a specialized RCD with the function of suppressing high
harmonics or a general-purpose RCD with relatively large residual current.
2) High leakage current warning
DANGER
The AC drive generates high leakage current during running, which ows
through the PE conductor. Earth connection must be done before connection of power
supply. Earthing shall comply with local regulations and related IEC standards.

MD380 User Manual Safety Information and Precautions

3) Motor insulation test
Perform the insulation test when the motor is used for the first time, or when it is
reused after being stored for a long time, or in a regular check-up, in order to prevent
the poor insulation of motor windings from damaging the AC drive. The motor must be
disconnected from the AC drive during the insulation test. A 500-V mega-Ohm meter is
recommended for the test. The insulation resistance must not be less than 5 MΩ.

4) Thermal protection of motor
If the rated capacity of the motor selected does not match that of the AC drive,
especially when the AC drive's rated power is greater than the motor's, adjust the motor
protection parameters on the operation panel of the AC drive or install a thermal relay
in the motor circuit for protection.
5) Running at over 50 Hz
The AC drive provides frequency output of 0 to 3200 Hz (Up to 300 Hz is supported if
the AC drive runs in CLVC and SFVC). If the AC drive is required to run at over 50 Hz,
consider the capacity of the machine.
6) Vibration of mechanical device
The AC drive may encounter the mechanical resonance point at some output
frequencies, which can be avoided by setting the skip frequency.
7) Motor heat and noise
The output of the AC drive is pulse width modulation (PWM) wave with certain harmonic
frequencies, and therefore, the motor temperature, noise, and vibration are slightly
greater than when the drive runs at power frequency (50 Hz).

Safety Information and Precautions MD380 User Manual
- 14 -
8) Voltage-sensitive device or capacitor on output side of the AC drive
Do not install the capacitor for improving power factor or lightning protection voltage-
sensitive resistor on the output side of the AC drive because the output of the AC drive
is PWM wave. Otherwise, the AC drive may suffer transient overcurrent or even be
damaged.

9) Contactor at the I/O terminal of the AC drive
When a contactor is installed between the input side of the AC drive and the power
supply, the AC drive must not be started or stopped by switching the contactor on or
off. If the AC drive has to be operated by the contactor, ensure that the time interval
between switching is at least one hour since frequent charge and discharge will shorten
the service life of the capacitor inside the AC drive.
When a contactor is installed between the output side of the AC drive and the motor,
do not turn off the contactor when the AC drive is active. Otherwise, modules inside the
AC drive may be damaged.

10) When external voltage is out of rated voltage range
The AC drive must not be used outside the allowable voltage range specied in this
manual. Otherwise, the AC drive's components may be damaged. If required, use a
corresponding voltage step-up or step-down device.
11) Prohibition of three-phase input changed into two-phase input
Do not change the three-phase input of the AC drive into two-phase input. Otherwise, a
fault will result or the AC drive will be damaged.

MD380 User Manual Safety Information and Precautions

12) Surge suppressor
The AC drive has a built-in voltage dependent resistor (VDR) for suppressing the surge
voltage generated when the inductive loads (electromagnetic contactor, electromagnetic
relay, solenoid valve, electromagnetic coil and electromagnetic brake) around the AC
drive are switched on or off. If the inductive loads generate a very high surge voltage,
use a surge suppressor for the inductive load or also use a diode.
Note
Do not connect the surge suppressor on the output side of the AC.
13) Altitude and de-rating
In places where the altitude is above 1000 m and the cooling effect reduces due to thin
air, it is necessary to de-rate the AC drive. Contact Inovance for technical support.
14) Some special usages
If wiring that is not described in this manual such as common DC bus is applied,
contact the agent or Inovance for technical support.
15) Disposal
The electrolytic capacitors on the main circuits and PCB may explode when they are
burnt. Poisonous gas is generated when the plastic parts are burnt. Treat them as
ordinary industrial waste.
16) Adaptable Motor
• The standard adaptable motor is adaptable four-pole squirrel-cage asynchronous
induction motor or PMSM. For other types of motor, select a proper AC drive
according to the rated motor current.
• The cooling fan and rotor shaft of non-variable-frequency motor are coaxial, which
results in reduced cooling effect when the rotational speed declines. If variable
speed is required, add a more powerful fan or replace it with variable-frequency
motor in applications where the motor overheats easily.
• The standard parameters of the adaptable motor have been congured inside the
AC drive. It is still necessary to perform motor auto-tuning or modify the default
values based on actual conditions. Otherwise, the running result and protection
performance will be affected.
• The AC drive may alarm or even be damaged when short-circuit exists on cables
or inside the motor. Therefore, perform insulation short-circuit test when the motor
and cables are newly installed or during routine maintenance. During the test,
make sure that the AC drive is disconnected from the tested parts.
