Special conditions of use to be observed
• The OPTIMASS measuring system and MFC converter must be included in the equipoten-
tial bonding system of any hazardous area installation.
• Allow the electronics to de-energise before opening the electronics enclosure inside a
hazardous area. The time needed to de-energise is 35 minutes for temp. class T6 and 10
minutes for Temp. class T5. There is no waiting time for Temp. class T1
• Use certifi ed cable glands on cable entries. Use a certifi ed plug to seal unused cable
entries.
• Install connecting cables as fi xed wiring so that they are protected against damage.
Connecting cables must not exceed the parameters specifi ed in the Supplementary
Instructions for Hazardous Areas.
• For details on the relationship between: maximum permissible ambient temperature, maxi-
mum medium temperature, maximum surface temperature and the relevant temperature
class for each individual meter, please refer to the tables provided in the relevant meter
Handbook and/or the Supplementary Instructions for Hazardous Areas.
If the hygienic installation requires the meter to
be self draining, mount the meter at an angle.
DO NOT mount the meter horizontally!
