NOTICE
Shielding/extension of connecting cables
Warning to avoid damage to property
 Apply shielded cables directly (without any intermediate terminals if at all possible).
 If intermediate terminals are necessary, take the shortest route to applying the shielding
to the terminal.
 Avoid long connecting wires without shielding.
 Use a separate, shielded extension cable to implement an extension on site.
NOTICE
High electromagnetic interference
Excessive electromagnetic interference can lead to sporadic problems with flame detection
and even prevent it.
 Connect chassis earth (earthing bolt at the device) to functional earth (FPE).
It is a connection between the mass of the supply voltage and FPE prepared.
NOTICE
EMC emission testing
It was ascertained during the type test that the device meets the EMC emissions require-
ments. A separate EMC emissions test is not necessary after installation.
5.1.2 Electrical Safety – Requirements to Be Met by Third-party Manufacturers
DANGER!
Analogue output current loop - Protection against electric shock
Measuring circuits must be separated safely to dangerous active parts according to EN 61140
„Protection against electric shock …“.
 You achieve this by double or reinforced isolation according to EN 61010-1 „Safety re-
quirements for electrical equipment for measurement, control and laboratory use“.
WARNING!
Radio interference suppression of the output contacts
In the interests of safety, ensure when installing the output contacts that:
 The user suppresses radio interference in such a way that the contacts of the safety relay
contact output cannot be shorted by defective components of the suppressor circuitry.
