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.
