Max. permitted temperature for
continued operation in cabinet is +5 to
+55°C
(41 to 131°F).
Measured just below the I/O module.
Modules on compact MTUs on a vertical
DIN rail allow +5 to +40°C (41 to 104°F)
ambient temperature.
S800 equipment does not require radio
proof enclosures.
Communication, pulse transducers and
analog circuits for Low Level (RTD Pt,
thermocouples) must be shielded up to
the S800 I/O modules
See Section 2.2.3, Cable Routing in
Enclosures.
Check that there is no tension in the
wiring.
