1.2 SAFETY INSTRUCTIONS
1.3 GROUNDING AND GROUND FAULT PROTECTION
The Compact VFD 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 variable frequency drive has been designed
1
for fixed installations only.
Do not perform any measurements when the frequency converter
2
is connected to the mains.
Do not perform any voltage withstand tests on any part of the
3
VFD. The product safety is fully tested at factory.
Prior to measurements on the motor or the motor cable, discon-
4
nect the motor cable from the frequency converter.
Do not open the cover of VFD. Static voltage discharge
5
from your fingers may damage the components. Opening
the cover may also damage the device. If the cover of the VFD
is opened, warranty becomes void.
