Appendix A. CE Mark compliance
A1. Introduction
For CE Mark compliance, the XDP must meet both the
EMC and LVD directives.
Attention European customers!
CE Mark compliance is required for all units
used in EU countries.
A2. EMC compliance
For EMC compliance, the electrical connections must
be shielded and grounded as shown in Table 2 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.
Table 2: Wiring modifications for EMC compliance
Connection Wiring modification
Power
• When connecting the power,
select the cable entry closest to
the chassis ground.
• Use shielded cable* to connect
the power to the xdp enclosure.
Connect the shield to the nearest
chassis ground terminal.
• Connect the power line ground
wire to the nearest chassis
ground terminal.
Input/output
• Use shielded cable* to interconnect
the model xdp enclosure with any
external i/o devices.
• Connect the shields to the nearest
chassis ground terminal.
*Wires enclosed in a properly-grounded metal conduit
do not require additional shielding.
A3. LVD compliance
For compliance with the European Union’s low voltage
directive, the XDP 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 unit.
NOTE: If the instructions in this appendix are followed, the
unit will comply with the low voltage directive.
