Maintenance, calibration and work on equipment
a) Updates outside the hazardous
area:
Remove the positioners from the
plant. Update them outside the haz-
ardous area.
b) Updates on site:
Updates on site are only permitted
after the plant operator presented a
signed hot work permit.
After updating has been completed, add the
current firmware to the nameplate; this can
be done using labels.
13 Maintenance, calibration and
work on equipment
Interconnection with intrinsically safe cir -
cuits to check or calibrate the equipment in -
side or outside hazardous areas is to be
performed only with intrinsically safe cur -
rent/voltage calibrators and measuring in -
struments to rule out any damage to com -
ponents relevant to explosion protection.
Observe the maximum permissible values
specified in the certificates for intrinsically
safe circuits.
