DANGER
Potentially explosive atmosphere
The analyzer keys must not be pressed if a potentially explosive atmosphere may be present.
If operation using the keyboard is necessary, a hot work permit is absolutely essential.
WARNING
Improper laying of shielded cables
Risk of explosion through compensating currents between hazardous area and the
non‑hazardous area.
• Shielded cables that cross into hazardous areas should be grounded only at one end.
• If grounding is required at both ends, use an equipotential bonding conductor.
WARNING
Lack of equipotential bonding
Risk of explosion through compensating currents or ignition currents through lack of
equipotential bonding.
• Ensure that the device is potentially equalized
• The cable cross-section of the equipotential bonding cable must be greater than or equal to
the connecting cable of the electronics
CAUTION
Incorrect connection
Devices may only be connected and disconnected when in a deenergized state. This also
applies to the SUB-D connections.
Particular reference is made here to the PROFIBUS DP connection. The bus must be switched
o󹪜 when the plug on the analyzer is connected or disconnected. Please observe the
information in Section PROFIBUS DP (Page 34) with regard to the bus connection of PROFIBUS
DP.
The plug connectors must be mechanically locked.
