13-4 Considerations to measuring devices

All the cables and leads connected to the drive or filter should be regarded as active sources of
electrical noise. For inspection or service, use measuring devices or equipment that are CE marked. If
they require an external power supply, use one, which is separate or well insulated from that of the
drive system.
Even for a system that comprises CE marked equipment and devices only, an EMC compliance test
may be required if the whole system is exported from one country to another. Ask the local
government for details.

13-5 Installation into a metal cabinet

(1) Install the drive unit in a metal cabinet and put the EMI filter on the power source cable as shown
in Fig. 13-2.
(2) The power source cable and motor cable outside the metal cabinet should be shielded and as
shortest as possible. Electrically connect the shield to the earth terminal of the motor.
