Attention:
For the input module 0980 ESL 301-xxx, the two contacts 1
and 5 are not required for the power supply to the actuators. However,
these two contacts are connected to each other on the connector and
socket side to enable 5-pin transmission of the power supply to a
downstream module.
Attention:
Only use power supply units for the system/sensor
and actuator supply that correspond to PELV (Protective Extra
Low Voltage) or SELV (Safety Extra Low Voltage). Power supplies
according to EN 61558-2-6 (transformers) or EN 60950-1 (switching
power supply units) fulfill these requirements.
