 Electrical Connection

Carry out any work on live equipment in compliance with the national safety and accident prevention
regulations. Carry out electrical installation in compliance with the relevant regulations. In particular,
follow the installation instructions ensuring electromagnetic compatibility (EMC), e.g. shielding,
grounding, filter arrangement and laying of cables. This also applies to equipment with the CE mark.
It is the responsibility of the manufacturer of the system or machine to ensure conformity with EMC
limits.

Your supplier or Omron Yaskawa Motion Control representative must be contacted when using leak-
age current circuit breaker in conjunction with frequency inverters.

In certain systems it may be necessary to use additional monitoring and safety devices in compli-
ance with the relevant safety and accident prevention regulations. The frequency inverter hardware
must not be modified.

 Introduction

This manual was compiled to help system manufacturers using OMRON YASKAWA Motion Control
(OYMC) frequency inverters design and install electrical switch gear. It also describes the measures
necessary to comply with the EMC Directive. The manual's installation and wiring instructions must
therefore be followed.

Our products are tested by authorized bodies using the standards listed below.

Product standard: EN 61800-3:1996

 Measures to Ensure Conformity of OYMC Frequency inverters to the EMC Directive

OYMC frequency inverters do not necessarily have to be installed in a switch cabinet. 

It is not possible to give detailed instructions for all of the possible types of installation. This manual
therefore has to be limited to general guidelines.

All electrical equipment produces radio and line-borne interference at various frequencies. The
cables pass this on to the environment like an aerial.

Connecting an item of electrical equipment (e.g. drive) to a supply without a line filter can therefore
allow HF or LF interference to get into the mains.

The basic countermeasures are isolation of the wiring of control and power components, proper
grounding and shielding of cables.

A large contact area is necessary for low-impedance grounding of HF interference. The use of
grounding straps instead of cables is therefore definitely advisable.

Moreover, cable shields must be connected with purpose-made ground clips.
