Manipulation of the control elements may lead to serious injury and death.
– You should prevent any possibility of the control elements being ma-
nipulated through the use of a spare control element.
– Keep the spare control element in a safe place and protect it from un-
authorised access.
– If spare control elements are used, these must be installed as de-
scribed under Exchange of control elements [ 16].
– If the original control elements are replaced with spare control ele-
ments, the original control elements must be destroyed before dis-
posal.
