1-2.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;
Process
Type
Explanation
Before
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!
● 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!
When
installing
Danger
● 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!
Note
● 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.
When
wiring
Danger
● 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!
● 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, otherwie 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!
Before
energizing
Note
● 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
