Interface Cables
As of January 1, 1996, most products shipped to the European Community must comply with the
EMC Directive 89/336/EEC, which covers radio frequency emissions and immunity tests. In
addition, as of January 1, 1997, some products shipped to the European Community must also
comply with the Product Safety Directive 92/59/EEC and Low Voltage Directive 73/23/EEC,
which cover general safety practices for design and workmanship. MKS products that meet
these requirements are identified by application of the CE Mark.
To ensure compliance with EMC Directive 89/336/EEC, an overall metal braided shielded cable,
properly grounded at both ends, is required during use. No additional installation requirements
are necessary to ensure compliance with Directives 92/59/EEC and 73/23/EEC.
Note
1. An overall metal braided, shielded cable, properly grounded at both
ends, is required during use to meet CE specifications.
2. To order an overall metal braided shielded cable, add an “S” after the
cable type designation. For example, to order a cable to connect a
1249 unit to a 248 valve, use part number CB251-2-10; for a braided
shielded cable use part number CB251S-2-10.
