Among other things, these include the followingactivities• Insertion and removal of components• Connecting or disconnecting from fieldbus, antenna, D-Sub, ETHERNET orUSB connections, DVI ports, memory cards, configuration andprogramming interfaces in general and service interface in particular:• Operating DIP switches, coding switches or potentiometers• Replacing fusesWiring (connecting or disconnecting) of non-intrinsically safe circuits is onlypermitted 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 isnot exceeded by more than 40 % due to transient faults (e.g., when powering thefield supply).Product components intended for intrinsically safe applications may only bepowered by 750-606 or 750-625/000-001 bus supply modules.Only field devices whose power supply corresponds to overvoltage category I orII may be connected to these components.Pos : null /Dokumentation allgemei n/Gli ederungs elemente/---Seitenwec hs el--- @ 3\mod_1221108045078_0.doc x @ 21810 @ @ 1
