When installing transmitters
from third parties, observe the
maximum permissible power
consumption of 3 W.
See header TS500 with electron‐
ics in
Table 11-9 Dust Ex i/tb (Page 137)
and
Table 11-10 Type 2N (Page 138).
When installing transmitters
from third parties, observe the
maximum permissible power
consumption of 1 W. The maxi‐
mum surface temperature of the
TS500 enclosure is assumed to be
85 °C.
Notice!
If the maximum permissible am‐
bient temperature of the trans‐
mitters from third parties is less
than 85 °C, run the following cal‐
culation:
