CE Compliance
In regard to CE Compliance, refer to the WBK17 Declaration
of Conformity (p/n 1064-0740). As stated in that document,
one of the several requirements for CE compliance is the use
of a WBK17 CE kit (p/n WBK17-CE-Kit). Contact the factory
or your service representative should you desire detailed
information.
The Declaration of Conformity is shipped with the WBK17
module.
