Due to the dual connection, maximum wire cross-sections of 4 x 0.75 mm

can be accommodated. For long
supply lines, use 4 x 0.75 mm
2
cables to achieve a low voltage drop on the supply lines. 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. You can obtain a replacement plug from your Beckhoff Sales using the following
ordering option:
• C9900-P916: Power supply connector for CP39xx, round connector IP65 with strain relief for the
