Precautions
Motor insulation inspection
Before using the motor for the first time, before using it for a long time, and during regular
inspection, the motor insulation should be checked to prevent damage to the inverter due to the
insulation failure of the motor winding. During insulation inspection, the motor wiring must be

EM760 Series High Performance Vector Drive User Guide
6
separated from the inverter. It is recommended to use a 500V voltage megohmmeter, and it should
be ensured that the measured insulation resistance is not less than 5MΩ.
Thermal protection of the motor
If the selected motor does not match the rated capacity of the inverter, especially when the rated
power of the inverter is greater than the rated power of the motor, be sure to adjust the motor
protection related parameter values in the inverter or install a thermal relay in front of the
motor to protect the motor.
Operation above power frequency
Some inverters can provide output frequencies of 0.00Hz to 600.00Hz/0.0Hz to 3000.0Hz. If the
customer needs to run the motor above the rated frequency, please consider the bearing capacity
of the mechanical device. Otherwise, there will be equipment damage and even life-threatening
accidents.
When there is a varistor on the output side or a capacitor to improve power factor
The output of the inverter is PWM wave. If the output side is installed with a capacitor for
improving power factor or a varistor for lightning protection, it is easy to cause instantaneous
overcurrent of the inverter or even damage the inverter. Please do not use it.
Use other than rated voltage
It is not suitable to use the inverter outside the allowable working voltage range specified in
the manual, otherwise it will easily cause damage to the components in the inverter. If necessary,
please use the corresponding step-up or step-down device for voltage transformation.
Lightning strike protection
This series of inverters is equipped with surge current protection device, which has a certain
self-protection ability for inductive lightning. Customers should also install lightning
protection device at the front end of the inverter for frequent lightning occurrences.
Altitude and Derating Usage
In areas with an altitude of more than 1000m, the cooling effect of the inverter is deteriorated
due to the thin air, and it is necessary to derate the use (every 100m of height, derate by 1%,
and the maximum altitude is 3000m; when it exceeds 50 °C, it is necessary to press The temperature
is derated by 1.5% for every 1°C increase in temperature, and the maximum operating temperature
is 60 °C). In this case, please contact our company for technical consultation.
Pay attention to the scrapping of the inverter
The electrolytic capacitors of the main circuit and the electrolytic capacitors on the printed
board may explode when they are burned. Toxic gas will be generated when the plastic parts are
burned. Please dispose of them as industrial waste.
