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:
T = T - ∆T1D - ∆T2D

∆T1D = 22K (max. permissible
power consumption of 1 W)
∆T2D = See Table 11-9 Dust Ex i/tb
(Page 137) and
