Section 1: Conditions of safe operation
1. Conditions of safe operation
Ignorance of these instructions can result in serious injury or death to
personnel or damage to the frequency converter.
1.1. Threats and warnings
Incorrect installation or use of the AFC200 frequency converter may cause a
risk to life, human health or irreparable damage to the device.
RISK OF ELECTRIC SHOCK
•
Installation, operation, maintenance and repair of the device must be
performed only by properly qualified and authorized personnel.
•
Before switching on the power supply voltage, make sure that the
frequency converter has been correctly installed and all housing
elements have been properly assembled.
•
It is forbidden to touch the voltage terminals of the frequency converter
connected to the power supply voltage.
•
After connecting the converter to the power supply voltage, its internal
components (except for the control terminals) are on the power supply
potential. Touching these components can cause an electric shock.
•
When the converter is connected to the power supply voltage, dangerous
voltage occurs at its output U, V, W terminals even when the motor is not
running.
•
Externally supplied control circuits may carry dangerous voltage even
when the input power supply voltage of the frequency converter is
switched off.
•
After disconnecting the device from the power supply voltage, the
dangerous voltage is still present for about 5 minutes.
•
Don’t make any changes to the connections when the converter AFC200
is connected to the power supply voltage.
•
Before working with the frequency converter, electric motor cable or
electric motor, wait minimum 5 minutes after disconnecting the power
supply voltage and make sure that there is no dangerous voltage at the
connection terminals.
Attention!
The lack of the voltage at the connection terminals is not
synonymous with the lack of dangerous voltage in the internal DC circuit
of the frequency converter.
•
The frequency converter is not designed to be installed in a
flammable/explosive environment as it may cause a fire/explosion.
