Chapter Two: Installation Interface Cables

Interface Cables
As of January 1, 1996, all products shipped to the European Community must comply with the
EMC Directive 89/336/EEC, which covers radio frequency emissions and immunity tests. MKS
products that meet these requirements are identified by application of the CE Mark.
Note
1. An overall metal braided shielded cable, properly grounded at both
ends, is required 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 an overall metal
braided shielded cable, for a 41/42/51/52
unit, use part number
CB41S-1.
Connecting a Pressure Switch with a Type “D” Connector
The interface cable, CB41S-1, has a 9-pin female Type “D” connector (to attach to the pressure
switch) on one end and 2 foot flying leads (6 wire) on the other end. Use the flying leads end of
the cable to connect to your system. To ensure CE compliance, you must properly ground the
flying leads by connecting the shield (drain) lead to the main ground on your system. Refer to
Figure 4, page 15, to identify the shield (drain) lead.
Connecting a Pressure Switch with a Flying Leads Cable
When connecting a pressure switch equipped with a flying leads cable, you must connect the bare
metal shield (drain) wire to the main ground on your system to achieve CE compliance. Refer to
Figure 4, page 15, to identify the shield (drain) lead.
