4. Design and function
4.4 Voltage supply
The low-pressure controller is factory set for connection to a voltage supply of DC 24 V.
The power supply connector is located on the rear panel.
DANGER!
Electric shock hazard! Before removing the fuse, the power supply must
be removed from the plug.
Operation using a defective power supply unit (e.g. short circuit from the
mains voltage to the output voltage) can result in life-threatening voltag-
es at the instrument!
Only the original power supply unit included in initial delivery (Mascot
model 9926) should be used.
1. Design the wiring particularly carefully when connecting to other devices. Under
certain circumstances, internal connections in third-party devices (e.g. GND connect-
ed to the ground) can lead to impermissible voltages that could compromise or even
destroy the function of the device itself or a device connected to it.
2. The mains plug must always be plugged in to a mains socket and be accessible, so
that one can always remove it from the mains socket without difficulty.
