Product overview
4.1 Electrical connections on the rear
1) USB interface
2) RS-232 interface
3) Connection for power supply unit
4.2 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!
Operation using a defective power supply unit (e.g. short circuit from the mains
voltage to the output voltage) can result in life-threatening voltages at the instrument!
Only the original power supply unit included in initial delivery (Mascot model 9926)
should be used.
·
Design the wiring particularly carefully when connecting to other devices. Under certain
circumstances, internal connections in third-party devices (e.g. GND connected 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.
·
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.
