To connect the 2-wire cable (drive wires):
1. Use twisted-pair 18 AWG (0,75 mm
2
) 2-wire cable. Ensure that the
cable is shielded, continuous from the booster amplifier to the
sensor’s explosion-proof junction box. Two methods can be used:
• Metallic conduit
• Shielded or armored cable (do not place the 2-wire cable and 9-
wire cable in the same cable tray)
2. Connect the wires:
a. Connect terminal 1 at the sensor (see Figure 10) to terminal 1 at
the booster amplifier (see Figure 11).
b. Connect terminal 2 at the sensor to terminal 2 at the booster
amplifier.
3. If the cable has a drain wire:
a. At the sensor end, clip the drain wire and leave it disconnected.
b. At the booster amplifier end, connect the drain wire to the internal
ground screw. See Figure 11.
4. If the cable has a braid, terminate it in the cable gland at both ends.
