1. Safety Information and Precautions
In this manual, the notices are graded based on the degree of danger:
Danger
Indicates that failure to comply with the notice will result in severe personal injury or
even death.
Warning
Indicates that failure to comply with the notice will result in personal injury or
property damage.
Read this manual carefully so that you have a thorough understanding. Installation, commissioning or
maintenance may be performed in conjunction with this chapter. EMHEATER will assume no liability or
responsibility for any injury or loss caused by improper operation.
1.1 Safety Information
Before
installation Danger

Do not use damaged or missing components frequency inverter. Failure to
comply will result in personal injury.

Please use the electric motor with upper B insulation class. Failure to comply
will result in personal injury.
During
installation
Danger

Install the frequency inverter on incombustible objects such as metal, and keep it
away from combustible materials. Failure to comply may result in a fire.
Warning
When two frequency inverters are laid in the same
cabinet, arrange the
installation positions properly to ensure the enough cooling effect.

Do not drop wire residue or screw into the frequency inverter. Failure to comply
will result in damage to the frequency inverter.
Wiring
Danger

Wiring must be performed only by qualified personnel under instructions
described in this manual. Failure to comply may result in unexpected accidents.

A circuit breaker must be used to isolate the power supply and the frequency
inverter. Failure to comply may result in a fire.

Ensure that the power supply is cut off before wiring. Failure to comply may
result in electric shock.

Connect the frequency inverter to ground properly by standard. Failure to
comply may result in electric shock.
Warning

Never connect the power supply cables to the output terminals (U, V, W) of the
Frequency inverter. Failure to comply will result in damage to the frequency
inverter.

Make sure that all the connecting wires comply with the requirement of EMC
and the saf
ety standard in the region. Use wire sizes recommended in the
manual. Failure to comply may result in accidents.
Never connect the braking resistor between the DC bus terminals (P+) and (P-).
Failure to comply may result in a fire.
Before
power-on
Check that the following requirements comply with:
The voltage class of the power supply is consistent with the rated voltage class of

Danger
the frequency inverter. The input terminals (R, S, T) and output terminals (U, V,
W) are properly connected. No short-
circuit exists in the peripheral circuit. The
wiring is fastened. Failure to comply will result in damage to frequency inverter.
Cover the frequency inverter properly before power-on to prevent electric shock.
Before
power-on
Warning

Do not perform the voltage resistance test on any part of the frequency inverter
because such test has been done in the factory. Failure to comply will result in
accidents.
All peripheral devices must be connected properly under the instructions
described in this manual. Failure to comply will result in accidents.
After
power-on
Danger
Do not open the frequency inverter’s cover after power-
on to prevent from
electric shock.
Do not touch the frequency i
nverter with wet hand and its peripheral circuit to
prevent from electric shock.

Do not touch the terminals of the frequency inverter (including the control
terminals). Failure to comply may result in electric shock.
Do not touch the U, V, W terminal or mo
tor connecting terminals when
frequency inverter automatically does safety testing for the external high-voltage
electrical circuit. Failure to comply may result in electric shock.
Warning
Note the danger during the rotary running of motor when check
the parameters.
Failure to comply will result in accidents.

Do not change the factory default settings of the frequency inverter. Failure to
comply will result in damage to the frequency inverter.
During
operation
Danger
Do
not go close to the equipment when selected the restart function. Failure to
comply may result in personal injury.

Do not touch the fan or the discharging resistor to check the temperature. Failure
to comply will result in personal injury.
Signal detection must be performed only by qualified personal during operation
Warning

Avoid objects falling into the frequency inverter when it is running. Failure to
comply will result in damage to frequency inverter.
Do not start/stop the frequency inverter by tur
ning the contactor ON/OFF.
Failure to comply will result in damage to the frequency inverter.
Maintenance
Danger
Do not repair or maintain the frequency inverter at power-
on. Failure to comply
will result in electric shock.

Repair or maintain the frequency inverter only after the charge light on
frequency inverter 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.
Repair or mai
ntenance of the frequency inverter may be performed only by
qualified personnel. Failure to comply will result in personal injury or damage to
the frequency inverter.

3.Installation of Frequency Inverter
3.1 Installation environment
1. The place with indoor vents or ventilation devices.
2. The environment temperature shall be -10℃~40℃. If the temperature is over 40℃but less than 50℃, better to
take down the cover of frequency inverter or open the front door of cabinet to facilitate heat dissipation.
3. Try to avoid high temperature and wet place; the humidity shall be less than 90% without frost deposit.
4. Avoid direct sunlight.
5. Keep away from flammable, explosive and corrosive gas and liquid.
6. No dust, floating fiber and metal particles.
7. Install on the place without strongly vibration. And the vibration should be not over 0.6G, Especially pay
attention to far away from the punching machine, etc.
8. Keep away from electromagnetic interference source.
3.2 Installation direction and space
In order to not affect the service life of frequency inverter and reduce its performance, note for its installation
direction and space and correctly fasten it.
Diagram3-1 Ventilating duct installation dimension diagram of frequency inverter
Please install the frequency inverter vertically, to send out the heat upward, and pay attention to direction of
frequency inverter to avoid inversion.
If there are several units of frequency inverter installed, please install them side by side, do not to install up and
down.

With the operation panel, the inverter can be used to modify the function parameters, the inverter working status
monitoring and the inverter running control (starting, stopping). The appearance and function are as follows:
Diagram 4-1Operatin panel
1. Description of indicator:
RUN: OFF indicates that the frequency inverter is in the stop state and ON indicates that the frequency inverter is
in the running state.
LOCAL: It indicates whether the frequency inverter is operated by operation keypad, terminals or remoter
(communication). OFF indicates keypad operation control state; ON indicates terminals operation control state;
Blinking indicates remote operation control state.
DIR: It is Forward/Reversal indicator, ON indicates forward rotation.
TRIP: Tunning/ Torque Control/Fault indicator
When the indicator is ON, it indicates torque control mode. When the indicator is blinking slowly, it indicates the
auto-tuning state. When the indicator is blinking quickly, it indicates the fault state.
