The plug for the power supply is specified for 16 A and can accommodate wire cross-sections of up to 1.5 mm2. For long supply lines, use 1.5 mm2 cables to achieve a low voltage drop on the supply line. There should be at least 22 V at the power supply plug of the control panel, so that the control panel remains switched on during voltage fluctuations. The plug is included in the delivery. You can obtain a replacement plug from your Beckhoff Sales using the following ordering option:
