APPENDIX
Use the inverter under the conditions of overvoltage category II (usable regardless of the earth condition of the power
supply), overvoltage category III (usable with the earthed-neutral system power supply) and pollution degree 2 or lower
specified in IEC664.
– To use the inverter FR-F 740 EC of 00770 or more (IP00) under the conditions of pollution degree 2, install it in the
enclosure of IP 2X or higher.
– To use the inverter FR-F 740 EC under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.
– To use the inverter FR-F 740 EC of 00620 or less (IP20) outside of an enclosure in the environment of pollution
degree 2, fix a fan cover with fan cover fixing screws enclosed.
On the input and output of the inverter, use cables of the type and size set forth in EN60204 Appendix C.
The operating capacity of the relay outputs (terminal symbols A1, B1, C1, A2, B2, C2) should be 30VDC, 0.3A. (Relay
outputs are basically isolated from the inverter internal circuit.)
Control circuit terminals on
page 4
are safely isolated from the main circuit.
Environment
A.1.4 Machine directive
The frequency inverter itself is not a machine in the spirit of the EU machine directive. The start up of the frequency
inverter in a machine is prohibited so long until it has been confirmed that the entire machine complies with the provisions
of Directive 89/392/EWG (machine directive).
