NOTICE
The cables connected to the frequency inverters may not be sub-
•
jected to high-voltage insulation tests.
Use copper cables designed for an ambient temperature of at
•
least 30 °C.
In the case of UL/CSA installations: Only use 75°C copper cables.
The earth leakage current of the frequency inverter may exceed
•
AC 3.5 mA or DC 10 mA.
4.1 EMC information and connection
The frequency inverter is designed according to the requirements and limit
values of product norm EN 61800-3 with an interference immunity factor
GB
(EMI) for operation in industrial applications. Electromagnetic interference is
to be avoided by expert installation and observation of the specific product
information.
Measures
Install the frequency inverters and commutating chokes on a metal
•
mounting panel. Ideally, the mounting panel should be galvanized, not
painted.
Provide proper equipotential bonding within the system or plant. Plant
•
components such as electrical cabinets, control panels, machine frames
must be connected by means of PE cables.
• Connect the shield of the control cables to ground potential properly, i.e.
with good conductivity, on both sides (shield clamp). Mount shield clamps
for cable shields close to the device.
• Connect the device and its components to a grounding point via short
cables.
Avoid excessive cable length and loosely suspended cabling.
•
Contactors, relays and solenoid valves in the control cabinet must be pro-
•
vided with suitable interference suppression components.
