9.1 EMC Installation
Requirements
This product has been designed to meet the certication 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 tting RF suppression
components, such as ferrite absorbers, line lters etc., in the event that RF elds 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.
2. Avoid routing leads alongside cables and products that are, or could be, a source of
Caution
1. In the interest of safety and functionality this product must be installed by
a qualied engineer, abiding by any local regulations.
2. Voltages dangerous to human life are present at some of the terminal
connections of this unit. Ensure that all supplies are de-energised before
attempting any connection or disconnection.
3. These products do not have internal fuses therefore external fuses must
be used to ensure safety under fault conditions.
interference.
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.
