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.
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.
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.
Chemical
Specific hazards will be the subject of product data. As a matter of good working practice, oral contact
should be avoided.
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.
Product Data Sheets
These should be checked for information that supplements or replaces that given above.
