The connections X3 / 2 and X3 / 7 (GND) are directly connected to X4 / Vs-, X4 / V-. There is no
AGND potential in accordance with module AX501. In module AX501, AGND is connected to
GND via a resistor.
Both sensor shield connections of X3 are interconnected and jointly connected to FE via 10 MW
|| 4 nF.
The terminal blocks of X2 and X3 have the following connection data:
● Conductor cross section, single wire/ flexible: 0.14 mm² to 1.5 mm²
● Conductor cross section, flexible with wire end ferrule (without plastic ferrule): 0.25 mm² to
1.5 mm²
● Conductor cross section, flexible with wire end ferrule (with plastic ferrule): 0.25 mm² to 0.5
mm²
