3. Inspection and safety precautions
Euronorm frequency inverters have been tested and inspected before leaving factory. After purchasing, please check if its pack-
age is damaged due to careless transportation, and if the specifications and model of the product are consistent with your order
requirements. For any problem, please contact your local authorized Euronorm dealer or directly contact this company.
3.1 Safety precautions
Safety precautions in this manual are divided into the following two categories:
Danger:
The dangers caused by failure to perform required operation, may result in serious injury or even death;
Caution:
The dangers caused by failure to perform required operation, may result in moderate injury or minor injury,
and equipment damage;

e
installation
Danger
●
When unpacking, if control system with water, parts missed or component damaged are found, do not install!
●
If packing list does not match the real name, do not install!
When installing
Danger
●
Gently carry with care, otherwise there is the risk of damage to equipment!
●
Please do not use the damaged driver or the frequency inverter with missed pieces, otherwise there is the risk of injury!
●
Do not use your hand to touch the control system components, otherwise there is the risk of electrostatic damage!
No
te
●
Please install the unit on the metal or flame retardant objects; away from combustible material. Failure to do so may cause a fire!
●
Never twist the mounting bolts of the equipment components, especially the bolt with the red mark!
When
wiring
Danger
●
Do not let the lead wires or screws fall into the driver. Otherwise which may cause damage to the driver!
●
Keep the driver installed in the place where less vibration, avoid direct sunlight.
●
When two or more converters are installed in a cabinet, please pay attention to the installation location, ensure the good heat
dissipation effect.
Befor
e energizing
No
te
●
Must comply with this manual’s guidance, any construction shall be performed by a professional electrician, otherwise there
would be the unexpected risk !
●
A circuit breaker must be set between the inverter and the power supply to separate them, otherwise it may cause a fire!
Danger
●
Verify if power is a zero-energy status before wiring, otherwise there is a risk of electric shock!
●
The inverter shall be grounded correctly according to standard specifications, otherwise there is a danger of electrical shock!
●
Ensure that the distribution line meets the regional safety standards of EMC requirements. The diameter of used wire shall refer to
the recommendations of this manual. Otherwise it may cause an accident!
●
Never directly connect braking resistor to the DC bus P(+) and P(-) terminals. Otherwise it may cause a fire!
●
Encoder must use the shielded wire, and the shielding layer must ensure the single-ended grounded!
After
energizing
Danger
●
Please confirm whether the input power voltage is same as the inverter rated voltage; wiring positions of power input terminals(R,
S, T) and output terminals(U, V, W) are correct or not; and note that if there is a short circuit in the peripheral circuit connected to
driver, if the connected lines are tight, otherwise it may cause damage to the driver!
●
Do not need to perform withstand voltage test for any part of the inverter, this product has been tested before leaving factory.
Otherwise it may cause an accident!
During operation
Danger
●
The inverter’s cover plate must be closed before power on. Otherwise it may cause an electric shock!
●
Wiring of all external accessories must comply with the guidance of this manual, please correctly wiring in accordance with the
circuit connection methods described in this manual. Otherwise it may cause an accident!
No
te
●
Do not open cover plate after energizing. Otherwise there is a risk of electric shock!
●
Do not touch the driver and peripheral circuits with wet hands. Otherwise there is a risk of electric shock!
●
Do not touch any input and output terminals of the inverter. Otherwise there is a risk of electric shock!
●
The inverter automatically perform the safety testing for the external strong electrical circuit in the early stages of energizing,
therefore never touch the driver terminals(U, V, W) or motor terminals, otherwise there is a risk of electric shock!
●
If you need to identify the parameters, please pay attention to the danger of injury during motor rotation. Otherwise it may cause
an accident!
●
Please do not change the inverter manufacturer parameters. Otherwise it may cause damage to this unit!
When
maintaining
Danger
●
Do not touch the cooling fan and the discharge resistor to feel the temperature. Otherwise it may cause burns!
●
Non-professional personnel is not allowed to detect signal when operating. Doing so may cause personal injury or damage to this unit!
No
te
●
When the inverter is operating, you should avoid that objects fall into this unit. Otherwise cause damage to this unit!
●
Do not start/stop the driver by switching on/off contactor. Otherwise cause damage to this unit!
During
maintenance
Danger
●
Do not perform repairs and maintenance for the live electrical equipment. Otherwise there is a risk of electric shock!
●
The repairs and maintenance task can be performed only when the inverter bus voltage is lower than 36V,Otherwise, the residual
charge from capacitor would cause personal injury!
●
Non-well-trained professional personnel is not allowed to perform repairs and maintenance of inverter. Doing this may cause
personal injury or damage to this unit!
●
After replacing the inverter, parameter settings must be redone, all pluggable plugs can be operated only in the case of powering off!
