The wiring depends on the heating option selected for the sensor:
• One power supply produces enough power for WMT700 without heating (0 W) or with
transducer heating only (30 W).
• WMT700 with transducer and arms heating (150 W) requires an additional power
supply.
The heating power supply wires are internally connected to each other. If
the connection cable has two positive heating supply wires, both must be connected to
each other. Leaving one terminal unconnected or connecting it to the ground may cause
a malfunction or a short-circuit in the power supply.
CAUTION!
