Restrictions on use
WARNING:
Hazard through pressure/temperature
▸
Only use the Interface Unit within the pressure and temperature limits as
specified in these Operating Instructions as well as on the type plate.
WARNING:
Dangerous voltage
▸
Do not open the enclosure while energized.
▸
Only operate internal switches if the device is not live or the area is safe.
▸
Do not connect or disconnect the circuits unless the power has been turned
off or the area is safe.
▸
It must be ensured that the rated voltage U
M
60 V is not exceeded when
connected to devices not belonging to the system, in particular external
power supply devices, power supply units, etc.; except for the main power
supply with U
M
< 253 V.
▸
A suitable main power switch must be provided.
▸
Do not use the device when cables or terminals are damaged.
WARNING:
Risk of explosion
In a closed enclosure, degree of contamination 2 according to IEC 60664-1 is
assumed. Opening the enclosure is only permitted when the environment does
not endanger degree of contamination 2 inside the enclosure (e.g. through
penetration of conductive dust or moisture).
WARNING:
Device restrictions/high risk use
The device firmware is not designed for any use requiring fail-safe performance
in which the failure of the computer system could lead to death, serious
personal injury, or severe environmental damage, and therefore must not be
used in such areas.
