Figure 9. Power supply wiring for remote booster amplifier 
Wiring from the remote booster amplifier to the sensor
The remote version of the booster amplifier requires connection of two 
cables from the booster amplifier to the junction boxes on the sensor:
• 9-wire cable (signal wires) — This cable is supplied by Micro Motion, 
and is pre-attached to the booster amplifier.
• 2-wire cable (drive wires) — In some locations, this cable may be 
supplied by Micro Motion. If the cable is not supplied, use twisted-
pair 18 AWG (0,75 mm
2
) 2-wire cable.
To connect the 9-wire cable (signal wires):
1. Do not modify connections at the booster amplifier.
2. Do not place the 9-wire cable and 2-wire cable in the same cable tray.
3. At the sensor end of the 9-wire cable (see left side of Figure 10):
a. Clip all four drain wires and leave them disconnected.
b. Clip the red and brown wires and insulate them.
c. Matching by color, connect the remaining wires (except for the 
orange wire) to the corresponding terminals from the sensor 
feedthrough.
d. The orange wire in the cable does not have a corresponding 
orange wire from the sensor. Connect the orange wire to the 
terminal indicated in Figure 10. 
e. Terminate the cable braid inside the cable gland.
