Wiring from the remote booster
amplifier to the sensor
For intrinsically safe junction box wiring (see left side of figure below):
• Terminate factory-supplied 9-wire cable. Match wire colors to the
corresponding terminal wire colors from the remote booster amplifier.
• Orange wire in cable does not have corresponding orange wire from
sensor. Note: Terminate the orange wire in cable to the terminal shown
in diagram below.
• Clip remaining wires (brown and red) of cable (intrinsically safe side
only) and insulate.
For explosion-proof junction box wiring (see right side of figure below):
Install user-supplied drive wiring, shielded 18 AWG (0,75 mm
2
) 2-wire
cable, from remote booster amplifier terminals 1 and 2 to sensor
terminals 1 and 2. (See figure on page 29 for wiring at booster amplifier.)
