1.2 Safety instructions
The Vacon 10 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 10. 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 10. Static voltage discharge
from your fingers may damage the components. Opening the
cover may also damage the device. If the cover of Vacon 10 is
opened, warranty becomes void.
1.3 Earthing and earth fault protection
The Vacon 10 frequency converter must always be earthed with an earthing conduc-
tor connected to the earthing terminal. See figure below:
MI1 - MI3
• The earth fault protection inside the frequency converter protects
only the converter itself against earth faults.
• If fault current protective switches are used they must be tested
with the drive with earth fault currents that are possible to arise in
fault situations.
