1.2 SAFETY INSTRUCTIONS
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.
1
The SmartVFD COMPACT frequency converter has been designed
for fixed installations only.
2
Do not perform any measurements when the frequency converter
is connected to the mains.
3
Do not perform any voltage withstand tests on any part of Smart-
VFD COMPACT. The product safety is fully tested at factory.
4
Prior to making resistance measurements on the motor or the
motor cable, disconnect the motor cable from the frequency con-
verter.
5
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.
