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. 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.
Avoid routing leads alongside cables and products that are, or could be, a source of interference.
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 connection in to systems via Current
Transformers only, where one side is grounded.
ESD precautions must be taken at all times when handling this product.
