CE Mark Compliance A-1
January 2008
Introduction For CE Mark compliance, the XDP must meet both the EMC and 
LVD directives.
IMPORTANT: CE Mark compliance is required only for units used 
in EEC countries.
EMC Compliance For EMC compliance, the electrical connections must be shielded and 
grounded as shown in Table A-1 below. After all the necessary 
electrical connections have been made, seal any unused cable entry 
holes with standard conduit plugs or equivalent.
Note: If the instructions in this appendix are followed, the unit will 
comply with the EMC Directive 89/336/EEC.
LVD Compliance For compliance with the European Union’s Low Voltage Directive 
(73/23/EEC), the analyzer requires an external power disconnect 
device such as a switch or circuit breaker. The disconnect device must 
be marked as such, clearly visible, directly accessible, and located 
within 1.8 m (6 ft) of the XDP.
Note: If the instructions in this appendix are followed, the unit will 
comply with the Low Voltage Directive (73/23/EEC).
Table A-1:  Wiring Modifications for EMC Compliance
Connection Wiring Modification
Power 1. When connecting the power, select the cable 
entry closest to the chassis ground.
2. Use shielded cable* to connect the power to the 
XDP enclosure. Connect the shield to the 
nearest chassis ground terminal.
3. Connect the power line ground wire to the 
nearest chassis ground terminal.
Input/Output 1. Use shielded cable* to interconnect the Model 
XDP enclosure with any external I/O devices.
2. Connect the shields to the nearest chassis 
ground terminal.
*Wires enclosed in a properly-grounded metal conduit do not 
require additional shielding.
