compliance with low-voltage directive 73/23/EEC, a switch
is required.

• Do not install power-supply wiring in the same cable tray or
conduit as flowmeter cable.

• If conduit is used, connect a ½-inch NPT male conduit
connector to the conduit opening in the seal for power­supply wiring. See

Figure 1

.

• If conduit is not used, connect a ½-inch NPT male cable
gland to the conduit opening in the seal for power-supply
wiring. See

instructions that are shipped with the cable preparation kit.

CAUTION

Failure to seal amplifie r housing cou ld cause a short
circuit, which would result in measurement error or
flowmeter failure.

To avoid risk of condensation or excessive moisture
entering the amplifier housing:

• Seal all conduit openin gs.

• Install drip legs in cable or conduit.

• Fully tighten amplifier housing cover.

• Micro Motion D600 sensors comply with EMC directive
89/336/EEC and low-voltage directive 73/23/EEC, when
properly installed in accordance with these instructions.

• Terminal 1 is line, terminal 2 is neutral, and terminal 3 is
ground. See

Figure 1

• Ground the sensor with a maximum impedance of 1 ohm.
Connect and bond a user-s up pli ed g round wire to the earth
ground connection on the amplifier housing. See
