2.2 - REFERENCE TO THE STANDARDS: "CE" CERTIFICATION
The CD1-a amplifiers have been approved for their conformity with the EMC standards concerning the power
servos referenced in the EN 61800.3 standard regarding "electrical power servos with variable speed":
• EN 55011, Group 1, Class A regarding conducted and radiated radioelectric disturbances,
• EN 61000.4-2-3-4-5 regarding immunity.
Standard to be applied to the electrical equipments of industrial machines: EN 60204.1.
The amplifiers have been "CE" marked since year 2000.
2.3 - REFERENCE TO THE STANDARDS: "UL" LISTING
CD1-a series have been «

This product was evaluated to:
- the Third Edition of UL508C, the UL Standard for Power Conversion Equipment, dated May 2002 for the UL
Listing (USL),
- the CSA Standard for Industrial Control Equipment, C22.2 N° 14-95, dated August 1995 for the Canadian UL
Listing (CNL).
Providing that the manual is specifying that the end user has to provide an isolated power supply, for 24 VDC
auxiliary input protected by a 4 A UL Listed fuse, the power board is considered within a limited voltage/current
circuit per section 31.4 of UL508C. Therefore, spacings on the power board are not required to be evaluated per
section 31.2 of UL508C and were evaluated according to UL 840.
Per UL 840 (Second Edition, dated May 20, 1993) requirements, spacings are limited to 2.5 mm assuming
pollution degree 2 environment.
Ground connection is fixed in the frame of the device by a rivet, Avibulb masse, BN10-5168. The connector
complies with standard dimensions given in table 6.2 of UL 310, the standard for Electrical Quick connect
terminals.
