Relay connections
(compressor unit to AWT420 transmitter)
WARNING
• Isolate the compressed air unit and AWT420
transmitter from the mains power supply before
making electrical connections.
• Ensure all cable runs are safe and do not present a
trip hazard when routing/securing.
Referring to Figure 1:
1 Release the two door locks
unit door.
Referring to Figure 8:
2 Loosen the M20 cable gland entry on the base of the
compressed air unit and pass one end of the connection
cable through. Pass the other end of the cable through the
required cable gland entry on the transmitter refer to the
transmitter Operating Instruction (OI/AWT420-EN) for gland
entry options.
3 Make connections between the compressed air unit and
transmitter.

5 Proceed to "Mains voltage supply" to make the mains voltage
supply connection to the compressed air unit.
Mains voltage supply
(230 or 115 V AC)
WARNING
• Isolate the compressed air unit and AWT420
transmitter from the mains power supply before
making electrical connections.
• Ensure the voltage supply matches the supply
voltage specified on the instrument label
within the enclosure before making connections –
see Figure 1 on page 5.
• Ensure all cable runs are safe and do not present a
trip hazard when routing/securing.
Referring to Figure 8:
1 Loosen the M20 cable gland entry on the base of the
compressed air unit and pass the free end of the 3-core
mains supply cable through.
2 Make mains power supply connections to the compressed air
unit neutral/earth/live terminals.
3 Tighten the M20 mains supply voltage cable gland.
4 Close and lock the compressed air unit door – refer to Figure
1 on page 5.
5 Proceed to "Configuration" on page 11 to configure the
cleaning schedule.
