Safety instructions
Earthing and earth error protection
The Vacon 100 frequency converter must always be earthed on the
earth terminal
The U, V, and W motor terminals and the DC rail / brake
1 resistor -/+ terminals are live when the Vacon 100 is
connected to the mains, even if the motor is not running.
The I/O connectors for the controllers are electrically isolated
from the mains. However, even when the Vacon 100 is
2
disconnected from the mains, the relay outputs and other I/O
terminals may have a dangerous external voltage.
Before the frequency converter is connected to the mains,
3 make sure that the Vacon 100 covers and cable connections
are covered.
Do not carry out any measurements when the frequency
4
converter is connected to the mains.
After disconnecting the frequency converter from the mains,
wait until the fan stops and the control panel turns off (if no
panel is attached, see the indicators on the cover). Wait 5
5
minutes before performing any work on the Vacon 100
terminals.
Do not even open the cover before this time has passed.
Do not perform any insulation resistance tests on the Vacon
100. There is a specific procedure for carrying out such tests.
6
Failure to follow this procedure may cause damage to the
device.
