CE and EMC Guidelines
160 MMC Hardware Manual G & L Motion Control Inc.
11.5 Conformance with the EMC Directive
G&L Motion Control will be complying to the Directive by self-certification
to the following generic EMC standards:
1. EN50081-2 for industrial emissions using EN55011 (based upon
CISPR 11A)
2. EN50082-2 for industrial immunity using:
IEC 61000-4-2 (ESD- 4KV contact mode, 8 KV air discharge)
IEC 61000-4-3 (Radiated susceptibility)
IEC 61000-4-4 (Electrical fast transient)
IEC 6100-4-8 (Magnetic fields)
A statement of compliance will be made with the letters “EMC” or “CE” on
the product, but will be valid only if the product is installed properly.
11.6 Conformance With the Low Voltage Directive
G&L Motion Control will comply with the Directive by self certification to
the following standard:
EN 61131-2:1994/A11:1996 Low Voltage Requirements for
Programmable Controllers
A statement of compliance will be made with the letters “CE” on the product
but will be valid only if the equipment is properly installed.
11.7 Changes to the PiC Products
G&L Motion Control PiC products had originally been designed with a high
level of noise immunity and tested according to standards such as NEMA
showering arc and the original version of IEC 801-2. However, the EU
directive for immunity requires testing to standards that have more variables
and are more repeatable. The directive also requires control of emissions,
something that is not regulated in U. S. industrial environments.
As a result, changes have been made to the hardware modules within the PiC
product line. The changes have included the addition of filtering, re-routing
of foils and/or the addition of ground planes to printed circuit boards, use of
some conductive enclosures, provision for shielded wires* for peer-to-peer
communication, and internal connection of SPG to field side connectors.
*NOTE
A recommended shielded wire is Belden, 24 AWG (7X32), 9729
