Updates on site:
Updates on site are only permitted

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.
