Precautions
Motor insulation inspection
When the motor is used for the first time or after long-term storage or subject to regular inspection, its insulation
should be checked to prevent the inverter from damage caused by failure of the motor winding insulation. During
the insulation inspection, the motor must be disconnected from the inverter. It is recommended to use a 500V
megohmmeter. The measured insulation resistance must not be less than 5MΩ.
Thermal protection of motor
If the motor used does not match the rated capacity of the inverter, especially when the rated power of the inverter
is greater than that of the motor, the motor must be protected by adjusting the motor protection parameters of the
inverter or installing a thermal relay in front of the motor.
Operation above power frequency
Some inverters can provide 0.00Hz~600.00Hz/0.0Hz~3000.0Hz output frequency. When the motor needs to
operate above the rated frequency, please consider the capacity of the mechanical device. Otherwise, equipment
damage or even life-threatening accidents may occur.
Presence of voltage-dependent device or capacitor increasing the power factor on output side
The inverter outputs PWM waves. If there is a capacitor increasing the power factor or voltage-dependent resistor
for lightning protection on the output side, the inverter may be subjected to instantaneous overcurrent and even
damage. Do not use these devices.
Use beyond rated voltage
The inverter should not be used beyond the allowable working voltage range specified in this manual; otherwise,
components inside the inverter are prone to damage. If necessary, use the appropriate step-up or step-down device
for voltage transformation.
Lightning impulse protection
This inverter series is equipped with a surge current protection device for protection against induced lightning. In
lightning-prone places, a lightning protection device should be added before the inverter.
Altitude and derating
In areas with an altitude of more than 1,000m, where heat dissipation of the inverter is poor due to thin air,
derating is required (derating by 1% per 100m altitude increase to maximum 3,000m; for ambient temperature

User’s Guide for EM760 series high-performance vector inverter

above 50℃, derating by 1.5% per 1℃ temperature rise to maximum 60℃). Contact us for technical advice.
Precautions for scrapping of inverter
Burning of the electrolytic capacitors of the main circuit and printed circuit board may result in explosion, and
burning of plastic parts may generate toxic gases. Please dispose of the controller as a kind of industrial waste.
Scope of application
This product is not designed and manufactured as a device or system of vital importance. Do not use this product
in these cases.
This product is manufactured under strict quality management. When failure of this product may cause a major
accident or loss, please install a safety device.
Prevention of electric shock
Please read all requirements of safety precautions! Maintenance of the inverter must be carried out 10 min after the
main circuit is powered off and the display interface of the keyboard is disabled; otherwise, the residual charge in
the capacitor will do harm to the human body!

2.3 Installation Site Requirements and Management
Installation site
The installation site should meet the following conditions:
⚫The room is well ventilated.
⚫The ambient temperature is -10C to 50C.
⚫The controller should be free from high temperature and humidity (less than 90% RH) or rainwater
and other liquid droplets.

User’s Guide for EM760 series high-performance vector inverter
16
⚫Please install the inverter on a fire-retardant object (e.g. metal). Never install it on flammable objects
(e.g. wood).
⚫No direct sunlight.
⚫No flammable or corrosive gas and liquid, dust, oily dust, floating fibers or conductive dust.
⚫The installation foundation should be secured and vibration-free. Do not pose any obstacle within
1m behind the inverter cabinet, so as to provide some space for maintenance.
⚫Avoid electromagnetic interference and keep the controller away from interference sources.
Preventive measures
Take protective measures to the inverter during installation to prevent metal fragments or dust generated in
drilling and other processes from falling into the inverter. Remove the protection after installation.
2.4 Installation Direction and Space
The EM760 inverters are equipped with cooling fans for forced air cooling. To ensure good cyclic cooling
effects, the inverter must be installed in a vertical direction, and sufficient spaces must be reserved between the
inverter and adjacent objects or baffles (walls). Refer to Fig. 2-2.

2.6 Through-wall installation
EM760 0R7G/1R5P~160G/185P support through-wall installation, which can realize dissipating 70% of the
total heat generated out of the device (cabinet), so as to reduce heat accumulation. Besides, through-wall
installation may also prevent entry of wood chips, paper scraps, dust, metal dust and other debris into the inverter
and improve reliability of the inverter.
①Use a tool to remove
screws on the top and
bottom sides of the panel
②Turn the right side of the
panel by hand to open the
panel
③Turn the panel, and it can be
turned finally to around 110°
