Information on wiring
• If you are wiring your configuration, you must take into account the impact of cable
length on the supply voltage to the ET 200eco PN (permitted tolerance).
• The maximum infeed current of the terminal block is 10 A for 1L+ non-switched and 10 A
for 2L+ switched.
Do not exceed these values.
