Installation and Connection
3.4.1
Connecting the instrument air
 Connect the instrument air supply to the FIDOR.
3.4.2
Connecting the combustion air
 Connect the combustion air if an external combustion air supply is used
3.4.3
Connecting the fuel gas (hydrogen)
Recommendation:
– Fit a pressure monitor on the fuel gas cylinder which monitors the cylinder pressure
and emits a signal at a certain residual pressure (e.g. 10 bar).
– If the FIDOR is integrated in an enclosed system cabinet:
Install an H2 flow limiter for the fuel gas supply in the system cabinet and, if
required, install a hydrogen sensor (H2 Sensor) (< 25% LEL).
 Lay the lines.
– Only use analytically pure tubes made of copper or stainless steel.
– Do not contaminate the insides of tubes during assembly
 Connect the fuel gas to the “Fuel gas” connection.
●
WARNING: Risk of explosions
The screw fitting for the fuel gas supply contains a flow limiter.
● The fuel gas inlet is marked “Fuel Gas”.
 Do not modify this screw fitting.
 Do not connect the fuel gas supply to any other screw fitting.
Connecting the test gases
3.4.4.1
Zero gas
 Connect the zero gas.
3.4.4.2
Reference gas
Recommendation:
Monitor the feed pressure of the reference gas with a pressure monitor which emits an
electric signal at a certain minimum pressure (e.g. 10 bar).
Connect the signal of the pressure monitor with the “External signal failure” control input.
 Connect the reference gas.
Subject to change without notice
