1.2 Safety instructions
1.3 Earthing and earth fault protection
The Vacon 10 frequency converter
must always
be grounded with a ground conduc-
tor connected to the grounding terminal. See figure below:
•
The earth fault protection inside the frequency converter protects only the
converter itself against ground faults.
•
If ground fault current protective switches are used, they must be tested
on the drive with ground fault currents that may arise in fault situations.
The motor can start automatically after a fault if the automatic restart
function has been enabled.
The Vacon 10 frequency converter has been designed for fixed installations
only.
Do not perform any measurements when the frequency converter is con-
nected to the mains.
Do not perform any insulation tests on any part of Vacon 10.
Product safety has undergone full factory testing.
Prior to measuring the motor or the motor cable, disconnect the motor
cable from the frequency converter.
Do not open the cover of Vacon 10. Static voltage discharge from your fin-
gers may damage the components. Opening the cover may also damage
the device. If the cover of Vacon 10 is opened, warranty becomes void.
