converter is not subjected to physical shock or vibration, and it must be

protected from rain and not placed in a place where the ambient temperature is

too high.

WARNING

The input power cord can only be permanently tightly connected. The

equipment must be grounded (in accordance with IEC 536 Class 1, NEC and

other applicable standards).

Even when the frequency converter is not working, the following terminals may

carry dangerous voltage:

- Power supply terminal R, S, T

- Motor connection terminal U, V, W

- Depends on the frame size, terminal +, -, BR

This equipment cannot be used as an emergency shutdown device. (refer to

EN 60204, 9.2.5.4)

CAUTION

The power cables, motor cables and control cables connected to the frequency

converter must be connected in a standardized manner to avoid inductive and

capacitive interference caused by the frequency converter.

WARNING

FT50 series frequency converter operates under high voltage.

Dangerous voltage exists on some parts of the electrical equipment during

operation.

According to the EN60204/IEC204 (VDE0113), the emergency shutdown

About maintenance

About disassembly and waste disposal

equipment damage or even serious personal injury (that is, there is a

potentially dangerous failure). Therefore, additional external precautions must

be taken or additional devices used to ensure safe operation must be installed,

even when a failure occurs (for example, install the independent current limit

switch, mechanical interlock, etc.)

After the input power is interrupted and powered on again, certain parameter

settings may cause the frequency converter to restart automatically.

In order to ensure that the motor overload protection operates correctly, the

motor parameters input to the frequency converter must be completely

consistent with the motor actually connected.

In order to ensure that the motor I2t over temperature protection operates

correctly, the motor parameters input to the frequency converter must be

completely consistent with the motor actually connected.

The motor over temperature protection function is provided in the frequency

converter. As per the P0426.M parameter setting, the I2t over temperature

protection function is activated by default. By setting the parameter P0426.M to

2-4, the motor over temperature protection function can also be performed by

using the external PTC via the IO expansion board temperature detection

input. Or it can be achieved by comparing the actual temperature measured by

the KTY84 sensor with the fault temperature set by the parameter P0428.M.

This equipment cannot be used as an emergency shutdown device. (refer to

EN 60204, 9.2.5.4)

1.3 Special Warnings

DANGER

Electric shock and danger to life due to other energy sources.

Touching live components can result in death or severe injury.

Only work on electrical devices when you are qualified for this job.

Always observe the country-specific safety rules.

Generally, the following steps apply when establishing safety:

1. Prepare for disconnection. Notify all those who will be affected by the

procedure.

2. Isolate the drive system from the power supply and take measures to

prevent it being switched back on again.

3. Wait until the discharge time specified on the warning labels has elapsed.

4. Check that there is no voltage between any of the power connections, and

between any of the power connections and the protective conductor

connection.

5. Check whether the existing auxiliary supply circuits are de-energized.

6. Ensure that the motors cannot move.

7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic

systems, or water. Switch the energy sources to a safe state.

8. Check that the correct drive system is completely locked.

After you have completed the work, restore the operational readiness in the

inverse sequence.

DANGER

Risk of electric shock and fire from supply networks with an excessively high

impedance.

Excessively low short-circuit currents can lead to the protective devices not

tripping or tripping too late, and thus causing electric shock or a fire.

In the case of a conductor-conductor or conductor-ground short-circuit, ensure

that the short-circuit current at the point where the converter is connected to

the line supply at least meets the minimum requirements for the response of

the protective device used.

You must use an additional residual-current device (RCD) if a

conductor-ground short circuit does not reach the short-circuit current required

for the protective device to respond. The required short-circuit current can be

too low, especially for TT supply systems.

Risk of electric shock and fire from supply networks with an excessively low

impedance.

Excessively high short-circuit currents can lead to the protective devices not

being able to interrupt these short-circuit currents and being destroyed, and

thus causing electric shock or a fire.

Ensure that the prospective short-circuit current at the line terminal of the
