1.2 Safety instructions
The Vacon 20 frequency converter has been designed for fixed
installations only.
Do not perform any measurements when the frequency con-
verter is connected to the mains.
Do not perform any voltage withstand tests on any part of
Vacon 20. The product safety is fully tested at factory.
Prior to measurements on the motor or the motor cable, dis-
connect the motor cable from the frequency converter.
Do not open the cover of Vacon 20. Static voltage discharge
from your fingers may damage the components. Opening the
cover may also damage the device. If the cover of Vacon 20 is
opened, warranty becomes void.
