Installation
7.1
Safety
The unit is designed in accordance with IEC 61010-1:2017 – Permanently connected use, Normal
condition. Installation category III, pollution degree 2, basic insulation for rated voltage.
7.2
EMC Installation Requirements
Whilst this unit complies with all relevant EU EMC (electro-magnetic compatibility) regulations,
any additional precautions necessary to provide proper operation of this and adjacent equipment
will be installation dependent and so the following can only be general guidance:
Avoid routing wiring to this unit alongside cables and products that are, or could be, a source of
interference.
The auxiliary supply to the unit should not be subject to excessive interference. In some cases, a
supply line filter may be required.
To protect the product against incorrect operation or permanent damage, surge transients must
be controlled. It is good EMC practice to suppress transients and surges at the source. The unit
has been designed to automatically recover from typical transients; however, in extreme
circumstances it may be necessary to temporarily disconnect the auxiliary supply for a period of
greater than 10 seconds to restore correct operation.
Screened communication leads are recommended and may be required. These and other
connecting leads may require the fitting of RF suppression components, such as ferrite absorbers,
line filters etc., if RF fields cause problems.
It is good practice to install sensitive electronic instruments that are performing critical functions
in EMC enclosures that protect against electrical interference causing a disturbance in function.
Warning
During normal operation, voltages hazardous to life may be present at some of the
terminals of this unit. Installation and servicing should be performed only by qualified,
properly trained personnel abiding by local regulations. Ensure all supplies are de-
energized before attempting connection or other procedures.
Terminals should not be user accessible after installation and external installation
provisions must be sufficient to prevent hazards under fault conditions.
This unit is not intended to function as part of a system providing the sole means of
fault protection - good engineering practice dictates that any critical function be
protected by at least two independent and diverse means.
