4.6 Electrical connection check
Perform the following checks after completing electrical installation of the measuring
device:
Device condition and specifications Notes
Are cables or the device damaged (visual inspection)?
−
Electrical connection of meter Notes
Does the supply voltage match the specifications on the nameplate? 85...260 V AC (45...65 Hz)
20...55 V AC (45...65 Hz)
16...62 V DC
Do the cables comply with the specifications? see Page 45
Do the cables have adequate strain relief?
−
Are the cables correctly segregated by type?
Without loops and crossovers?
−
Are the power-supply and fieldbus cables correctly connected? see the wiring diagram
inside the cover of the
terminal compartment
Are all screw terminals firmly tightened?
−
Have the measures for grounding/potential equalisation been correctly
implemented?
seePage58
Are all cable entries installed, firmly tightened and correctly sealed?
Cables looped as “water traps”?
−
Are all housing covers installed and firmly tightened? −
Electrical connection - PROFIBUS-DP/-PA Notes
Are all the connecting components (T-boxes, junction boxes, connec-
tors, etc.) connected with each other correctly?
–
Has each fieldbus segment been terminated at both ends with a bus
terminator?
–
Has the max. length of the fieldbus cable been observed in accordance
with the PROFIBUS specifications?
seePage48
Has the max. length of the stubs been observed in accordance with the
PROFIBUS specifications?
seePage46
Is the fieldbus cable fully shielded and correctly grounded? see Page 46
