2. The enclosure of the controller provides a
grounding terminal, and the user should install a
reliable grounding wire connected to it when
mounting and using the controller.
3. The controller’s cable entrance (1/2 NPT) must
be fitted with a cable entry device which is
Ex−approved through inspection of explosion
protection, in conformity with relevant standards of
GB3836.1-2000 and GB3836.2-2000 and has a
corresponding rating of explosion protection.
4. An appropriate heat−resistant cable should be
selected for use with the controller in an application
where the ambient temperature exceeds 70_C.
5. The principle of “Opening equipment’s cover is
strictly prohibited while its is active” must be abided
by when using and maintaining the controller in the
field.
6. The user must follow the relevant rules specified
by the product instruction manual, the “13th Section
