Power Supply Wiring
The Series 340 BN/MB requires 12-24 Volts AC or DC to operate. The power connections are made to the ORANGE header. The
connections are labeled beside the header. Observe the polarity shown on the label.
If a Badger Meter plug-in type power supply (Model A-1026 or A-503) is used, connect the black/white striped wire to the
terminal marked positive (+) and the black wire to the terminal marked negative (-).

NOTE:
Included with every Series 340 BN/MB is a 340IK kit containing a screw, lock washer and nut to connect the Series
340 BN/MB to earth ground. Connect the earth ground lug of the Series 340 BN/MB to a solid earth ground with as short
a wire as possible. This will help prevent electrical interference from affecting the Series 340 BN/MB’s normal operation.
