Technical data
2.9 Podule connector socket
The DX pump has a 2-way Podule Connector Socket in the top of the Podule. When the pump is shipped, this connector
is concealed by a black protective cover. If the connector will be used, this cover should be removed by levering with
a small screwdriver. The mating plug for this connector is supplied with the pump.
The connector is intended to drive a vent valve or fan connected to the two pins. The connector mating plug is shown
in Figure 4, with the polarity of the pins marked when the vent valve/fan is energised.
The podule connector plug is available as an accessory, see Section 7.4.
