5. Installation5.4.2 Power supply (preferably 230 V - 3/N/PE)WARNINGDanger from electrical equipmentDanger from electric shocksBefore removing the housing or accidental-contact protection, the equipmentmust be disconnected from the power supply.If it cannot be disconnected, protective equipment must be worn to ensure theprevention of electric shocks.A fixed energy supply connection must be established to the measuringdevice. The mains cable is connected to a residual current protective device for230 V / 50 Hz, 25 A / 30 mA in the device cabinet. The customer fuse protectionfor the energy connection must be designed accordingly.5.4.3 Measuring and operating data recordingThe interface lines for measuring values, control signals and operating anderror status messages agreed in the project must be provided by thecustomer. The terminal assignment can be found in the circuit diagrams.Attention! Before connecting the signal line for the measuring signal, the wirejumper at terminal X3 between contacts 16 and 17 (also 18 and 19 if thesecond measuring signal output is used) must be removed. The signal line isthen attached to the same terminal points.5.4.4 Exhaust gasWhen the gas sample has passed through the device and been analysed, itexits the device's gas duct. Depending on the project, this exhaust gas canalso be conveyed to its destination via a hose connection in the device roof.Once again, a bulkhead fitting with hose connection for DN 4/6 on both sidesserves for connection to a simple plastic hose, which in turn is led directly tothe destination or to a central exhaust gas system.5.4.5 CondensateThe condensate resulting from the gas drying phase is now pumped out of themeasuring device by a hose pump. The approx. 1.50 m long transparentcondensate hose end (DN 4/6) is led out through the side wall of themeasuring device. It is now possible to connect the hose end directly to thecondensate receptacle or to a central condensate collecting system. If thecondensate receptacle with level monitoring is used, you must ensure that thecables for the signal connection between level sensor and measuring deviceare installed according to the terminal plan.Generally the condensate receptacle is housed in the device cabinet.WARNINGCondensate fluid: Risk of skin irritationCondensate can give rise to specific dangers. These are dependent on thepollutants contained in the measuring gas. The receptacle must thereforealways be handled by appropriately trained personnel with the necessary careand with any required protective equipment.44 HM 1400 TRX
