INSTALLATION AND WIRING

(5) Motor overload protection

When using the electronic overcurrent protection function as motor overload protection, set the rated motor current in Pr.9 "electronic thermal O/L relay".

When connecting two or more motors to the inverter, install external thermal relays for individual motors.

2.3.8 Instructions for compliance with the European standards

2

(Only the FR-F540-0.75K to 55K units comply. We are now preparing to apply for for compliance with the other capacity models. The products conforming to the Low Voltage Directive carry the CE mark.)

(1) EMC Directive

1)Our view of transistorized inverters for the EMC Directive

A transistorized inverter is a component designed for installation in a control box and for use with the other equipment to control the equipment/device. Therefore, we understand that the EMC Directive does not apply directly to transistorized inverters. For this reason, we do not place the CE mark on the transistorized inverters. (The CE mark is placed on inverters in accordance with the Low Voltage Directive.) The European power drive manufacturers' organization (CEMEP) also holds this point of view.

2)Compliance

We understand that the transistorized inverters are not covered directly by the EMC Directive, but the machines/equipment into which they have been incorporated are covered by the EMC Directive and must carry the CE marks. Hence, we prepared the technical information "EMC Installation Guidelines" (information number BCN-A21041-202) so that machines and equipment incorporating transistorized inverters may conform to the EMC Directive more easily.

3)Outline of installation method

Install an inverter using the following methods:

*Use the inverter with a European Standard-compliant noise filter.

*For wiring between the inverter and motor, use shielded cables or run them in a metal piping and ground the cables on the inverter and motor sides with the shortest possible distance.

*Insert a line noise filter and ferrite core into the power and control lines as required.

Full information including the European Standard-compliant noise filter specifications are written in the technical information "EMC Installation Guidelines" (information number BCN-A21041-202). Please contact your sales representative.
