STEP 4. Wiring the booster amplifier 
Power supply wiring to the booster amplifier
The booster amplifier, whether mounted integrally or remotely with the 
D600 sensor, requires a separate AC power supply. To wire the booster 
amplifier power supply:
1. Remove screw and terminal cover before installing wiring. Grease 
O-ring and re-install cover before operating.
2. Provide 85-250 VAC power to terminal N/L2 and terminal L/L1. 
• For integral booster amplifier wiring, see Figure 8.
• For remote booster amplifier wiring, see Figure 9. 
CAUTION
Improper installation of wiring could cause 
measurement error or sensor failure.
• Shut off power before installing power-supply wiring.
• Follow all instructions to ensure sensor will operate 
correctly.
• Install drip legs in conduit or cable.
• Seal all conduit openings.
• Ensure integrity of gaskets, grease all O-rings, and 
fully tighten sensor junction-box cover, booster 
amplifier cover, core processor cover, and all 
transmitter housing covers.
WARNING
Improperly removing the booster amplifier housing 
cover in a hazardous area could cause an explosion.
In a hazardous area:
• Do not open booster amplifier housing cover while 
booster amplifier is energized.
• Wait at least 30 minutes after power is shut off before 
opening.
