1.3 GROUNDING AND GROUND FAULT PROTECTION

The SmartVFD COMPACT frequency converter must always be grounded with an
grounding conductor connected to the grounding terminal. See figure below:
•
The ground fault protection inside the frequency converter protects
only the converter itself against ground faults.
•
If fault current protective switches are used they must be tested
with the drive with ground fault currents that are possible to arise in
fault situations.
Safety
The SmartVFD COMPACT frequency converter has been designed
for fixed installations only.
Do not perform any measurements when the frequency converter
is connected to the mains.
Do not perform any voltage withstand tests on any part of Smart-
VFD COMPACT. The product safety is fully tested at factory.
Prior to making resistance measurements on the motor or the
motor cable, disconnect the motor cable from the frequency con-
verter.
Do not open the cover of SmartVFD COMPACT. Static voltage dis-
charge from your fingers may damage the components. Opening
the cover may also damage the device. If the cover of SmartVFD
COMPACT is opened, warranty becomes void.
