Special conditions
•
The power supply for the 'Feedback on the actuator
position using proximity switches (Pepperl & Fuchs SJ2-
SN)' circuit must be provided intrinsically safe in
accordance with the PTB 00 ATEX 2049 X certificate
according to application type 2.
•
It is only permissible to connect, disconnect, and switch
live circuits during installation or maintenance, or for the
purpose of carrying out repairs.
Note
It is considered very unlikely that a potentially hazardous
atmosphere would be present in Zone 2 at the same time
that installation or maintenance or repair work was being
carried out.
•
Only non-flammable gases must be used for pneumatic
power supply.
•
When used with gases from group IIA and a temperature
class of T1 for pneumatic power supply, the positioner
TZIDC may only be used outdoors or inside sufficiently
ventilated buildings.
•
For TZIDC, the gas supplied must be kept sufficiently free
of air and oxygen to prevent an ignitable atmosphere
from forming. The exhaust gas must always be
discharged outside.
•
Only use suited cable entries that meet the requirements
of EN 60079-11.
