2.3 Electrical connection on converter with intrinsically safe outputs
– Note information given on the instrument data plate (voltage,frequency)!
–
Electrical connection in conformity with IEC 364 or equivalent standard.
–
The PE ground conductor must be connected to the seperate U-clamp terminal in the
terminal box of the signal converter.
–
Do not cross or loop the cables in the back of the converter. Please use seperate cable
entries (PG or NPT) for power and signal cables.
Please ensure that the information about power given on the
data plate corresponds to the locally available mains voltage.
