Notes:
1. SITRANS LU AO receiver input is non-polarized.
2. Refer to associated application device instruction manual for wiring detail. Check that the communication parameter P740 (SITRANS LU10) is ON.
3. SITRANS LU AO interconnecting cable shield should be grounded at SITRANS LU10 only. Insulate shields at junctions to prevent inadvertent
grounding. Maximum individual loop length is 3 000 m (10 000 ft).
