For your safety Correct use The EV-CC-AC1-M3-CBC-RCM-ETH (-3G/-XP) charging controllers are designed exclu- sively for use in electric vehicle charging stations in accordance with IEC 61851-1, mode 3. The charging stations must be permanently connected to the power grid. No other uses are permitted.
Provide a disconnecting device for disconnecting the charging station from the voltage. Disposal Do not dispose of the device with household waste; it should instead be disposed of in ac- cordance with the currently applicable national regulations. 6 / 100 PHOENIX CONTACT 108191_en_04...
