224 Use in Hazardous Environments
Explosive atmosphere occurring simultaneously with assembly, installation or
repair work must be ruled out. Among other things, these include the following
activities
• Insertion and removal of components
• Connecting or disconnecting from fieldbus, antenna, D-Sub, ETHERNET or
USB connections, DVI ports, memory cards, configuration and
programming interfaces in general and service interface in particular:
•
•
Wiring (connecting or disconnecting) of non-intrinsically safe circuits is only
permitted in the following cases
• The circuit is disconnected from the power supply.
• The area is known to be non-hazardous.
Outside the device, suitable measures must be taken so that the rated voltage is
not exceeded by more than 40 % due to transient faults (e.g., when powering the
field supply).
Product components intended for intrinsically safe applications may only be
powered by 750-606 or 750-625/000-001 bus supply modules.
Only field devices whose power supply corresponds to overvoltage category I or
II may be connected to these components.
