Electric Connections - Siemens FIDAMAT 5E Instruction Manual

The supply gases (hydrogen, combustion air, zero gas and calibration gas(es)) must be available
with an inlet pressure of 3 bar above atmospheric. A higher zero gas and calibration gas pressure
leads to an increased consumption, a lower pressure may lead to an incorrect measurement since
additional sample gas may be drawn in.

Electric Connections

Warning! The following must be observed for the electric connections:
VDE 0100 "Regulations for the installation of power systems with mains
voltages below 1000 V".
A mains disconnection device must be provided in the building installation
(see rating plate for loading capacity).
– Check that the local power supply agrees with that specified on the rating plate on the device.
– The required signal cables must be connected to the 25-pin trapezoidal plugs X1, X2 and X3
and the 5-pin round plugs X4, X5 and X6 according to the pin assignment diagram.
