CAUTION
EQUIPMENT HAZARD
Negligence of this warning could cause total damage to the device.
The device is not waterproof!
Prevent the interior of the appliance from the penetration of water!
Take care that no external object (e.g. small metal part, metal powder) or liquid can get inside the device.
Avoid short circuit or ground fault at the output terminal blocks.
It is forbidden to connect any capacitor to the output. Regarding other filters, please ask the
manufacturer’s opinion.
Avoid using contactor at the output because the frequency converter may stop working due to switch-on
overcurrent.
If for other reasons using a contactor is necessary (e.g. switch-over between motors), the switchover of the
output of the frequency converter during operation must be prevented by latching.
Use the shortest possible earthing conductor and avoid earth loops.
Earthing conductors common with machines of higher power (e.g. welding machine, machine tool) must
not be used.
For wiring the control unit use shielded cable.
Use shielded twisted wires, and connect the shielding to the reference point of the inputs.
Observe proper electrostatic discharge procedures (ESD) when handling the frequency converter.
Failure to comply may result in ESD damage to the drive circuitry.
Do not operate the device with any visible damage on it or if its any part is missing.
Do not modify the circuitry of the frequency converter to avoid damages and expiring of the warranty.
Check all the wiring to ensure that all connections are correct after installing the frequency converter
and connecting other devices.
• Cables and fuses
At connecting the frequency converters use mains fuses and wires with cross-section as given in the table.
