Figure 3-4. MSP422 Wiring

NOTE!

The MSP422 is not intrinsically safe certified, and is therefore for use in non-hazardous (Ordinary Location) installations only.

The Mobrey MSP422 is a two-wire, loop-powered transmitter requiring an external 24 Vdc power supply. There is one M20x1.5 cable entry. A suitable conduit system or cable gland must be used to keep the weather-proof rating.

To cable the transmitter:

1.Make sure that the power supply is switched off.

2.Remove the cover of the transmitter housing.

3.Pull the cable through the cable gland/conduit.

4.Wire the transmitter as shown in Figure 3-4.

5.Connect the cable screen (shield) to ground at one end only.

6.Replace the cover, tighten the cable gland.

After Completing the Wiring

To maintain the weather-proof rating and hazardous area protection of the transmitter, ensure all cable glands, blanking plugs, and seals are in good condition.

Check that the cover seal is in good condition, and not twisted or misaligned in the seal location groove. When replacing the cover, tighten the three cover screws evenly to exert uniform pressure on the cover seal.
