Single-axis controllers General data and operating conditions 4 4.2 Protective insulation Danger! Operation of the controller on a phase earthed mains with a rated mains voltage of ≥ 400 V: ƒ The protection against accidental contact is not ensured without external measures. ƒ If protection against accidental contact acc. to EN 61800-5-1 is required for the control terminals of the controller and the terminals for the plugged-in device modules, – an additional basic insulation must be available. – the components to be connected must have the second basic insulation. Danger!
Dangerous electrical voltage When one common voltage source is used for control voltages in separate potential areas, the protective insulation between the separate potential areas is deactivated. Possible consequences: ƒ The specified protective insulations are not complied with. Protective measures: ƒ Use independent voltage sources. 4.2-5 EDS94SPP101 EN 3.1-04/2007
