U Supply voltage
When operating via a handheld terminal or via a PC with an operating program, a
minimum communication resistance of 250 Ω must be taken into account.
6.5.2 Shielding
You achieve optimum shielding against disturbances if the shielding is connected on both
sides (in the cabinet and on the device). If potential equalization currents are expected in
the plant, only ground shielding on one side, preferably at the transmitter.
When using in hazardous areas, you must observe the applicable regulations. Separate Ex
documentation with additional technical data and instructions is included with all Ex
systems as standard.
6.6 Post-connection check
Is the device or cable undamaged (visual inspection)?
Do the cables comply with the requirements?
Do the mounted cables have adequate strain relief?
Are all the cable glands installed, tightened and sealed?
Does the supply voltage match the specifications on the nameplate?
Is the terminal assignment correct ?
If required: Has protective ground connection been established?
If supply voltage is present, is the device ready for operation and do values appear on the display module?
Are all the housing covers installed and tightened?
Is the securing clamp tightened correctly?
