CONNECTION PLAN
Power supply
When several BUS devices are supplied by one 24 V AC voltage supply, it is to be ensured that all “positive” operating voltage input terminals (+)
of the field devices are connected with each other and all “negative” operating voltage input terminals (-) (=reference potential) are connected
together (in-phase connection of field devices).
In case of reversed polarity at one field device, a supply voltage short-circuit would be caused by that device. The consequential short-circuit
current flowing through this field my cause damage to it.
Therefore, pay attention to correct wiring.
