Chapter 5 AC drive Operating Instructions
5.1 Pre-operation Preparation
1) The input voltage should be within the allowable range of -15% to +10%.
2) The sequence of power on and power off should follow: when starting, close the control power
first, then close the high voltage power; when stopping, after the motor stops, then disconnect
the high voltage power, then disconnect the control power.
3) In the operation, the user should monitor the load operation at any time, and should stop in
time when abnormal conditions occur, and emergency stop when necessary.
4) There should be no abnormal electromagnetic interference in the vicinity of the AC drive
installation site.
5) The site operator must be trained and familiar with the structure of the equipment, and master
the operation process, safety regulations and precautions
6) High voltage operation procedures must be observed during maintenance, such as wearing
insulated gloves, insulated shoes, safety glasses, etc.
7) Prohibit single person operation and maintenance on site.
8) Safety fence must be set up (marked with "high voltage danger") and must not be removed
during use.
9) Do not put flammable materials (including equipment engineering drawings and manuals)
near the AC drive.
10) When handling or measuring the AC drive components, please do not let the various signal
and control lines short each other or touch other terminals
11) Do not run when the cabinet door is open or open the cabinet door during operation, otherwise
it will cause personal safety accidents.
12) Do not stop the cooling fan operation before disconnecting the high voltage, otherwise it will
cause the equipment to overheat and may damage the equipment.
13) When performing maintenance or replacing the power unit, the cabinet door must be opened
only after the AC drive has been disconnected from high voltage for more than 10 minutes (please
refer to the AC drive cabinet door sign for the specific time), and make sure the unit power light
is off before operation, because the AC drive is disconnected internally.
14) Dangerous high voltage may still exist for a short period of time after high voltage.
