CE Mark Compliance For CE Mark compliance, the AT868 must meet both the EMC and
LVD directives.
IMPORTANT: CE Mark compliance is required for all units intended
for use in EEC countries.
EMC Compliance For EMC compliance, the electrical connections must be shielded and
grounded as in Table 1-1 below. Also refer to Figure 1-1 on the next
page an example of acceptable wiring. 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 section are followed, the unit will
comply with the EMC Directive 89/336/EEC.
