Requirements of DC power supply of 6FC5203-0AF50-5AA0 Membrane Keyboard
The DC power supply is always referenced to ground and may not be generated by an autotransformer. User interfaces are powered via a DC power supply with protective separation according to EN 61800-5-1. In the case of supply lines 10 m, protectors must be installed at the device input in order to protect against lightning(surge). The DC power supply of 6FC5 203-0AF50-5AA0 Operator Keyboard must be connected to the ground/shield of the NC for EMC and/or functional reasons. For EMC reasons, this connection should only be made at one point. As a rule, the connection is provided as standard in the S7-300 l/Os. In exceptional circumstances when this is not the case, the ground connection of 6FC52030AF505AA0 Operator Panel Keypad should be made on the grounding rail of the NC cabinet (also refer to /EMC/EMC Installation Guide).
