16. CONFORMITY TO EC DIRECTIVES
The TD-240A digital indicator conforms to EC directives (based on the EC council of
ministers), carrying a CE mark.
- Low voltage directive: EN61010-1
- EMC directive: EN61326-1
When installing, attention should be given to the following.
1. Since the TD-240A is defined as an open type (built-in equipment), be sure to install
the TD-240A and fix to a panel or the like for use.
2. Use the attached power cable.
3. Use shielded cables for others (load cell, external I/O, option).
Attachment of a ferrite core
It is necessary to twist a power supply cable and sensor cables, such as a load cell,
around an attached ferrite core.（Common to AC spec. and DC spec.）
