3.4 Commissioning
A prerequisite for commissioning is correct installation of all electrical supply
lines and the pressure lines. All connections are arranged so that there are no
mechanical forces acting on the device.
CAUTION
Leak test
The pressure lines need to be checked for leaks before commissioning.
The device switches into normal mode as soon as the device is connected to a
power supply.
