4. ESD precautions must be taken at all times when handling this product.
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 connection in to systems via
Current Transformers only, where one side is grounded.
