Installation instructions
Warning
Use only power units which guarantee reliable isolation
of the operating voltages as per IEC 742/EN 60742/
VDE 0551 with at least 4 kV isolation resistance (Pro
tected Extra Low Voltage PELV). Switch power packs are
permitted, providing they guarantee reliable isolation
in accordance with EN 60950/VDE 0805.
By the use of PELV power units, protection against electric
shock (protection against direct and indirect contact) is
guaranteed in accordance with EN 60204−1/IEC 204.
Safety transformers with the adjacent symbol must be
used for supplying PELV networks. The module must be
earthed to ensure that it functions correctly (e.g. EMC).
