Servicing explosion-protected devices

If a part of the positioner on which the ex-
plosion protection is based needs to be ser-
viced, the positioner must not be put back
into operation until an expert has inspected
the device according to explosion protection
requirements, has issued a certificate stating
this or given the device a mark of confor-
mity.
Inspection by an expert is not required if the
manufacturer performs a routine check on
the device prior to putting it back into oper-
ation. The passing of the routine check must
be documented by attaching a mark of con-
formity to the device.
