WARNING
7-12
In the basic version, the unit has the following control connections:
♦ External 24 V supply
♦ 24 V voltage output, USS bus connection (RS485)
♦ Serial interface for PC or OP1S
♦ Control terminal strip.
Before the control cables and encoder cables are connected or
disconnected, the unit must be disconnected from the supply (24 V
electronic power supply and DC link/line voltage)!
If this measure is not observed, this can result in defects on the
encoder. A defective encoder can cause uncontrolled axis movements.
The external 24 V infeed and all circuits connected to the control
terminals must meet the requirements for safety separation as
stipulated in EN 50178 (PELV circuit = Protective Extra Low Voltage).
