Procedures shall be established for performing necessary maintenance to the SIS,
see also guidelines given in Proof Testing and Inspection on page 128.
The procedures shall include measures to be taken to maintain the safety functions
during testing, or if necessary, what additional steps need to be implemented to
reduce the risk during testing.
Procedures for performing maintenance to connected field devices (including
interfacing components, cabling etc.) shall describe necessary precautions to avoid
hazardous situations to arise.
If unintended activation of the device can imply any danger, measures external to
the AC 800M HI shall be planned (e.g disconnect power or activate mechanical
interlocks).
Procedures shall also be established to secure that test equipment used during
maintenance activities are properly calibrated and maintained.
For requirements for routine maintenance of the AC 800M HI, see user manuals AC
800M Controller Hardware, 3BSE036351* page 38 and S800 I/O Getting Started,
