4.2 Connecting the measuring unit
4.2.1 Supply voltage
Taking 4 to 20 mA test signal
A 4 to 20 mA test signal may be measured via the test terminals without interrupting the
measurement. To keep the corresponding measured error below 0.1 %, the current measuring
device should exhibit an internal resistance of < 0.7 .
4.2.2 Cable specification
• Endress+Hauser recommends using twisted, shielded two-wire cables.
• Terminals for wire cross-sections 0.5 to 2.5 mm
2
(20 to 14 AWG)
• Cable outer diameter: 5 to 9 mm (0.2 to 0.35 in) depends on the used cable gland (see technical
information)

4.2.4 Shielding/potential equalization
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.
4.3 Potential equalization
Observe the applicable regulations.
