Building Technologies
Fire Safety
Specialist electrical engineering knowledge is required for installation.
Only an expert is permitted to carry out installation work.
Incorrect installation can take safety devices out of operation unbeknown to a
layperson.
WARNING
Voltages up to AC 250 V on the terminals of the module!
Danger to life through contact with live components!
Use the housing FDCH221 if switching voltages >DC 60 V (ripple <10 % of
average value) or >AC 30 V (peak value max. 42.4 V) on the outputs.
Ensure that the cables are not supplied with voltage during installation.
Note the positive and negative poles.
Only connect one wire per terminal. This is the only way to ensure the connection
is failure-free for the entire service life of the device.
