12.1 EMC Installation Requirements
This product has been designed to meet the
certification of the EU directives when
installed to a good code of practice for EMC
in industrial environments,e.g.
1. Screened output and low signal input
leads or have provision for fitting RF
suppression components,such as ferrite
absorbers, line filters etc., in the event
that RF fields cause problems.
Note
:
It is good practice to install sensitive
electronic instruments that are
performing critical functions, in EMC
enclosures that protect against
electrical interference which could
cause a disturbance in function.
3. To protect the product against permanent
damage, surge transients must be limited
to 2kV pk. It is good EMC practice to
suppress differential surges to 2kV at the
source. The unit has been designed to
automatically recover in the event of a high
level of transients. In extreme
circumstances it may be necessary to
temporarily disconnect the auxiliary supply
for a period of greater than 5 seconds to
restore correct operation. The Current
inputs of these products are designed for
2. Avoid routing leads alongside cables and
products that are, or could be, a source of
interference.
4. ESD precautions must be taken at all
times when handling this product.
