4/ Electromagnetic Compatibility
To ensure conformance to the EC Directive 89/336/EEC, installation should adopt the following cable
arrangements:
All digital data cables and all analogue signal cables operating at or below 50 Volts
should be shielded either by braid, armouring or metal conduit.
Such shields should be earthed as closely as possible to the product. If for the
avoidance of ground loops it is not possible to earth these shields locally at low
frequencies, they should nevertheless be so earthed via a capacitor effective at
radio frequencies.
A single shield may be shared by any number of analogue signal cables.
5/ Functional Reliability
Reliability predictions, (including failure mode and effect analysis), are calculated by Rotork using statistical
methods and the resulting figures should only be used for statistical purposes. These predictions are only valid
if the maintenance procedures and maintenance intervals stated in Rotork documentation are observed.
6/ Environmental
Products should only be operated within the environment specified on the product data sheet. Take care not to
obstruct ventilation paths.
In the event of ingress of any fluid or spray, products should be immediately switched off, and cleaned and
dried by a competent person before re-use.
7/ Chemical
Specific hazards will be the subject of product data. As a matter of good working practice, oral contract
should be avoided.
8/ Independently Certified Products
Such products must not be modified in any way by the user, and must be applied, operated and maintained in
accordance with the relevant standards, certificates and reports.
9/ Product Data Sheets
These should be checked for information that supplements or replaces that given above.
