WARNING!
Only qualified personnel should conduct the tasks described in this section of the manual.
The transmitter is not fitted with a switch therefore a disconnecting device such as a switch or circuit breaker
conforming to local safety standards must be fitted to the final installation. It must be fitted in close proximity
to the transmitter within easy reach of the operator and must be marked clearly as the disconnection device
for the transmitter.
Remove all power from supply, relay and any powered control circuits and high common mode voltages
before accessing or making any connections.
Route signal leads and power cables separately, preferably in an earthed (grounded) flexible conduit.
The power supply is connected to the terminal board TB1.
The AW400 is shipped with the input voltage jumper set to 220 Vac. The selection between the

pc board.
See Figure 4 to change the jumper setting.
