Safety Precautions
Description of safety marks:
Danger: The misuse may cause fire, severe injury, even death.
Note: The misuse may cause medium or minor injury and equipment damage.
Use
DangerDanger
zThis series of inverter is used to control the variable speed operation of threephase
motor and cannot be used for singlephase motor or other applications. Otherwise,
inverter failure or fire may happen.
zThis series of inverter cannot be simply used in the applications directly related to the
human safety, such as the medical equipment.
zThis series of inverter is produced under strict quality management system. If the
inverter failure may cause severe accident or loss, safety measures, such as
redundancy or bypass, shall be taken.
Goods Arrival Inspection
NoteNote
zIf the inverter is found damaged or have missing parts, the inverter cannot be installed.
Otherwise, accident may be caused.
Installation
NoteNote
zWhen handling and installing the inverter, please hold the inverter bottom. Do not hold
the enclosure only. Otherwise, your feet may be injured and the inverter may be
damaged because of dropping.
zThe inverter shall be mounted on the fire retardant surface, such as metal, and kept far
away from the inflammables and heat source.
zKeep the drilling scraps from falling into the inverter during the installation; otherwise,
inverter failure may be caused.
zWhen the inverter is installed inside the cabinet, the electricity control cabinet shall be
equipped with fan and ventilation port. And ducts for heat dissipation shall be
constructed in the cabinet.

E5−H High Performance Universal Inverter User Manual
Safety Precautions
Wiring
DangerDanger
zThe wiring must be conducted by qualified electricians. Otherwise, electric shock may
happen or inverter damage.
zBefore wiring, confirm that the power supply is disconnected. Otherwise, electric shock
may happen or fire.
zThe PE terminal must be reliably grounded, otherwise, the inverter enclosure may
become live.
zPlease do not touch the main circuit terminals. The wires of the main circuit terminals
must not contact the inverter enclosure. Otherwise, electric shock may happen.
zThe connecting terminals for the braking resistor are 2/B1 and B2. Please do not⊕
connect terminals other than these two. Otherwise, fire may be caused.
zThe leakage current of the inverter system is more than 3.5mA, and the specific value of
the leakage current is determined by the operation conditions. The inverter and the
motor must be grounded to ensure the safety.
Wiring
NoteNote
zThe threephase power supply cannot connect to output terminals U/T1, V/T2 and
W/T3, otherwise, the inverter will be damaged.
zIt is forbidden to connect the inverter output terminals to the capacitor or LC/RC noise
filter with phase lead, otherwise, the internal components of the inverter may be
damaged.
zPlease confirm that the power supply phases, rated voltage are consistent with those
indicated by the nameplate, otherwise, the inverter may be damaged.
zDo not perform dielectric strength test on the inverter, otherwise, the inverter may be
damaged.
zThe wires of the main circuit terminals and the wires of the control circuit terminals shall
be laid separately or in a squarecrossing mode, otherwise, the control signal may be
interfered.
zThe wires of the main circuit terminals shall adopt lugs with insulating sleeves.
zThe sectional area of inverter input and output cables should be selected according to
the inverter power.
zWhen the cables between the inverter and the motor is longer than 100m, it is
suggested to use output reactor to avoid the inverter failure caused by the overcurrent of
the distribution capacitor.
zThe inverter equipped with a DC reactor must be connected with a DC reactor between
the terminals of ○
+1 and ○ +2, otherwise the inverter will not display after power on.

E5−H High Performance Universal Inverter User Manual
Safety Precautions
Operation
DangerDanger
zPower supply can only be connected after the wiring is completed and the cover is
installed. It is forbidden to remove the cover in live condition; otherwise, electric shock
may happen.
zWhen auto failure reset function or restart function is enabled, isolation measures shall
be taken for the mechanical equipment, otherwise, personal injury may be caused.
zWhen the inverter is powered on, its terminals are still live even when it is in stop state.
Do not touch the inverter terminals; otherwise electric shock may happen.
zThe failure and alarm signal can only be reset after the running command has been cut
off. Otherwise, personal injury may be caused.
NoteNote
zDo not start or shut down the inverter by switching on or off the power supply, otherwise,
the inverter may be damaged.
zBefore operation, please confirm if the motor and inverter are in the normal use range,
otherwise, the inverter may be damaged.
zThe heatsink and the braking resistor have high temperature. Please do not touch such
device; otherwise, you may be burnt.
zWhen the inverter is used by crane or lifting equipment, mechanical contracting brake
shall also be equipped.
zPlease do not change the inverter parameter randomly. Most of the factory settings of
the inverter can meet the operating requirement, and the user only needs to set some
necessary parameters. Any random change of the parameter may cause the damage of
the mechanical equipment.
zIn the applications with power frequency and variable frequency switching, the two
contactors for controlling the industrial frequency and variable frequency switching shall
be interlocked.
Maintenance, Inspection
DangerDanger
zIn the poweron state, please do not touch the inverter terminals; otherwise, electric
shock may happen.
zIf cover is to be removed, the power supply must be disconnected first.
zWait for at least 10 minutes after power off or confirm that the CHARGE LED is off
before maintenance and inspection to prevent the human injury caused by the residual
voltage of the electrolytic capacitor in main circuit.
zThe components shall be maintained, inspected or replaced by qualified electricians.

E5−H High Performance Universal Inverter User Manual
Safety Precautions
NoteNote
zThe circuit boards have large scale CMOS IC. Please do not touch the board to avoid
the circuit board damage caused by ESD.
Others
DangerDanger
zIt is forbidden to modify the inverter unauthorizedly; otherwise, human injury may be
caused.

Chapter 2 Inverter Installation
2.1 Environment for Product Installation
Do not install the inverter in the sites with oil mist, metal powder and dust.
Do not install the inverter in the sites with hazardous gas and liquid, and corrosive, combustible and
explosive gas.
Do not install the inverters in salty sites.
Do not install the inverter in the sites with direct sunlight.
Do not mount the inverter on the combustible materials, such as wood.
Keep the drilling scraps from falling into the inverter during the installation.
Mount the inverter vertically in the electric control cabinet, mount the cooling fan or air conditioner
to prevent the ambient temperature from rising to above 45 ºC.
For the sites with adverse environment, it is recommended to mount the inverter heatsink outside
the cabinet.
2.2 Mounting Direction and Space
In order not to reduce the inverter cooling effect, the inverter must be mounted vertically, and certain
clearance must be maintained, as shown in Figure 21 and Figure 22.
