DC power supply modules Wiring Important notes 6 6.6 6.6.1 6.6 Wiring 6.6.1 Important notes Danger! Dangerous voltage All power terminals remain live for at least three minutes after mains disconnection. Possible consequences: ƒ Death or severe injuries when touching the power terminals. Protective measures: ƒ Wait for at least three minutes before working on the power terminals. ƒ Check that all power terminals are deenergised. Danger! Dangerous voltage The leakage current to earth (PE) is > 3.5 mA AC or > 10 mA DC. Possible consequences: ƒ Death or severe injuries when the device is touched in the event of a fault. Protective measures:
ƒ Implement the actions required in the EN 61800-5-1. Especially: – Fixed installation – PE connection must conform to standards (PE conductor diameter ≥ 10 mm 2 or PE conductor must be connected twice) Stop! No device protection in the event of too high mains voltages The mains input is not fused internally. Possible consequences: ƒ Destruction of the device if the mains voltage is too high. Protective measures: ƒ Observe the max. permissible mains voltage. ƒ Fuse the device correctly on the supply side against mains fluctuations and voltage peaks. 6.6-1 EDS94SPP101 EN 3.1-04/2007
