A APPENDIX
A.1
Instructions for Compliance with the European Directives
A.1.1 EMC Directive
We have self-confirmed our inverters as products compliant to the EMC Directive (second environment of conforming
standard EN61800-3) and placed the CE mark on the inverters.
Remarks
First environment
Environment including residential buildings. Includes buildings directly connected without a transformer to the low
voltage power supply network which supplies power to residential buildings.
Second environment
Environment including all buildings except buildings directly connected without a transformer to the low voltage
power supply network which supplies power to residential buildings.
A.1.2 Notes
Install the inverter (and if necessary optional radio interference suppression filters) and perform wiring according to the
following instructions.
The FR-A 700 EC inverters are equipped with a built-in EMC filter. Set the EMC filter valid (initial setting).
Connect the inverter to an earthed power supply.
Install a motor and a control cable written in the EMC Installation Manual (BCN-A21041-204) according to the
instruction.
The maximum cable length (shielded cable) between the frequency inverter and motor required to maintain the limiting
values of the second environment is 5m when using the internal radio interference suppression filter.
Make sure that the frequency inverter, if required (optional external) radio interference suppression filters and the motor
are installed in compliance with generally recognised EMC installation regulations. It is not permitted to start up the
device unless the EMC guidelines are complied with.
A.1.3 Low Voltage Directive
We have self-confirmed our inverters as products compliant to the Low Voltage Directive (Conforming standard EN 50178)
and placed the CE mark on the inverters.
Outline of instructions
Do not use a residual current operated protective device (RCD) as an electric shock protector without connecting the
equipment to the earth. Connect the equipment to the earth securely.
Wire the earth terminal independently. (Do not connect two or more cables to one terminal.)
Use the cable sizes on page 7 under the following conditions.
– Ambient temperature: 40°C maximum
– Wire installation: With conduits for 400V, 00380 or less
On wall without ducts or conduits for 400V, 00470 or more
If conditions are different from above, select appropriate wire according to EN60204 Appendix C
TABLE 5.
Use a tinned (plating should not include zinc) crimping terminal to connect the earth cable. When tightening the screw,
be careful not to damage the threads.
For use as a product compliant with the Low Voltage Directive, use PVC cable whose size is indicated on page 7.
Use the moulded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard.
When using an earth leakage current breaker, use a residual current operated protective device (RCD) of type B
(breaker which can detect both AC and DC.) If not, provide double or reinforced insulation between the inverter and
other equipment, or put a transformer between the main power and inverter.
Use the residual current operated protective device (RCD) of type B (breaker which can detect both AC and DC).
However, be aware that also AC/DC sensitive earth leakage circuit breakers can be activated when turning the main
power on and off and that this behaviour can be improved through the use of AC/DC sensitive earth leakage circuit
breakers with adapted triggering curve designed for the inverter. If not, provide double or reinforced insulation between
the inverter and other equipment, or put a transformer between the main power supply and inverter.
