5 5.5 5.5.1 Multi-axis controllers Wiring Important notes 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. Note! Switching operations on the motor side of the controller are permitted for safety switch-off (emergency off). Please observe: ƒ When the controller is enabled, switching operations may lead to a response of the controller monitoring functions.
ƒ The switching elements on the motor side must be rated for DC voltages with U DCmax = 800 V. 5.5-2 EDS94SPP101 EN 3.1-04/2007
