CAUTION
There are two terminals connected in parallel for both positive and
negative rails of the heating voltage for the maximum current capacity. In
case the connection cable has parallel supply wires, they all have to be
connected to ensure current capacity. Leaving one terminal unconnected
or connecting it to the ground may cause a WMT700 malfunction or a
short circuit in
the power supply.
