1.4 Safety Instructions
1.4.1 Information Classification
The degree and type of hazard are marked unambiguously. All safety instructions are assigned to one of the following classes.
DANGER!
Safety instructions marked with
DANGER
indicate an imminently hazardous situation. A disregard of the notice
inevitably
leads to a
serious or even fatal accident
.
WARNING!
Safety instructions marked with
WARNING
indicate a potential hazardous situation. Failure to observe the instruction can
possibly
lead to a
serious or even fatal accident
or to
equipment/property damage
.
NOTE
Safety instructions marked with
NOTE
indicate a potential hazardous situation. Disregard of the notice may
possibly
result
in
property damage
.
1.5 Electromagnetic Compatibility
WARNING!
•
Risk of injury due to interference with signals and devices
Disturbed signals can cause unforeseen device reactions.
Carry out the wiring in accordance with the EMC measures. Failure to follow these instructions can result in death, serious
injury, or material damage
Measures for EMC
Effect
Device assembly
Use cable clamps for the shield support,
connect metal parts over a large area.
Good conductivity due to surface contact.
Switching devices such as contactors, relays
or solenoid valves with interference
suppression units or spark suppressors (e.g.
diodes, varistors, RC elements).
Reduce mutual interference couplings.
Wiring
Keep cables as short as possible.
Avoid capacitive and inductive interference.
Do not place fieldbus cables and signal cables
for direct and alternating voltage over 60 V
together in a cable conduit.
Avoid reciprocal interference.
Earth the shields of digital signal cables at both
ends or by means of conductive connector
housings.
Avoid interference on control cables, reduce
emissions.
CAUTION!
Safety instructions marked with
CAUTION
indicate potential danger. Failure to comply with the notice may
possibly
result in
an
accident
or
property damage
.
