of installation site is above 2000m.

The VFD should be used in proper environment (see Section 4.2.1 "Installation environment" for

details).

Prevent the screws, cables and other conductive parts from falling into the VFD,

As leakage current of the VFD during running may exceed 3.5mA, ground properly and ensure

the grounding resistance is less than 10Ω. The conductivity of PE grounding conductor is the

same with that of the phase conductor (with the same cross sectional area). For models higher

than 30 kW, the cross sectional area of the PE grounding conductor can be slightly less than the

recommended area.

R, S and T are the power input terminals, and U, V and W are output motor terminals. Connect

the input power cables and motor cables properly; otherwise, damage to the VFD may occur.

1.4.2 Commissioning and running

Disconnect all power sources applied to the VFD before terminal wiring, and wait

for at least the time designated on the VFD after disconnecting the power

sources.

High voltage presents inside the VFD during running. Do not carry out any

operation on the VFD during running except for keypad setting. For products at

voltage levels of 6, the control terminals form extra-low voltage circuits.

Therefore, you need to prevent the control terminals from connecting to

accessible terminals of other devices.

The VFD may start up by itself when P01.21 (restart after power down) is set to 1.

Do not get close to the VFD and motor.

The VFD cannot be used as "Emergency-stop device".

The VFD cannot act as an emergency brake for the motor; it is a must to install

mechanical brake device.

During driving permanent magnet synchronous motor, besides above-mentioned

items, the following work must be done before installation and maintenance.

1. Disconnect all the input power sources including main power and control

power.

2. Ensure the permanent-magnet synchronous motor has been stopped, and

the voltage on output end of the VFD is lower than 36V.

3. After the permanent-magnet synchronous motor is stopped, wait for at least

the time designated on the VFD, and ensure the voltage between "+" and "-"

is lower than 36V.

4. During operation, it is a must to ensure the permanent-magnet synchronous

motor cannot run again by the action of an external load; it is recommended

to install effective external brake device or disconnect the direct electrical

connection between permanent-magnet synchronous motor and the VFD.

Note:

Do not switch on or switch off input power sources of the VFD frequently;

For VFDs that have been stored for a long time, set the capacitance and carry out inspection and

pilot run on the VFD before use.

Close the front cover before running; otherwise, electric shock may occur.

1.4.3 Maintenance and component replacement
