®
VACON 20 X drive is connected to the mains, even if the motor is not running.
The control I/O-terminals are isolated from the mains potential. However, the
relay outputs may have a dangerous control voltage present even when
®
VACON 20 X drive is disconnected from the mains.
Do not make any connections to or from the frequency converter when it is con-
nected to the mains.
After disconnecting the AC drive from the mains, wait until the indicators on the
