 Batteries
Batteries must not be short circuited, or disposed of by burning. They must not be opened, punctured
or crushed. Large batteries should only be used in well ventilated places. Their cases are generally
ABS plastic resin and as such should be cleaned only with a damp cloth and not exposed to organic
solvents.
 Electromagnetic Compatibility
To ensure conformance to the EC Directive 2004/108/EC, 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 at the point of entry to the
product enclosure using cable glands designed for this purpose. 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. If this technique is adopted, it is the users’
responsibility to ensure that EMC is not compromised. A single shield may be shared by any number
of analogue signal cables.
All Ethernet cables must be screened and of good quality. Many screened Ethernet cables of low
quality have questionable screening efficacy.
 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 which supplements or replaces that given above.
