Emc Guidelines Compliance - YASKAWA L1000A Technical Manual

Guarding Against Harmful Materials
■
When installing IP00 enclosure drives, use an enclosure that prevents foreign material from entering the drive from above
or below.

◆ EMC Guidelines Compliance

This drive is tested according to European standards IEC/EN 61800-3: 2004, and complies with the European standards
IEC/EN 12015 (requires an optional AC reactor) and IEC/EN 12016.
Note: Make sure the protective earthing conductor complies with technical standards and local safety regulations. Because the leakage
current exceeds 3.5 mA when an EMC filter is installed, IEC/EN 61800-5-1 states that either the power supply must be
automatically disconnected in case of discontinuity of the protective earthing conductor or a protective earthing conductor with a
cross-section of at least 10 mm
EMC Filter Installation
■
The following conditions must be met to ensure continued compliance with European standards IEC/EN 12015 and IEC/
EN 12016. Refer to EMC Filters on page 479
Installation Method
Verify the following installation conditions to ensure that other devices and machinery used in combination with this
drive also comply with EMC guidelines.
1.
Install an EMC noise filter to the input side specified by Yaskawa for compliance with European standards.
2.
Place the drive and EMC noise filter in the same enclosure.
3.
Use braided shield cable for the drive and motor wiring, or run the wiring through a metal conduit.
4.
Keep wiring as short as possible. Ground the shield on both the drive side and the motor side.
