Figure 5-5 Terminology (time) for holding operation
Important information and instructions when installing the connecting cable
The brake connecting cable is included in the power cable. The insulation between the
power and brake connection is dimensioned for the basic insulation (VDE 600 V/1000V UL).
The relay K1, located between the coil and contact, must also have basic insulation in order
to protect the internal logic voltage (PELV=Protective Extra Low Voltage). The PELV supply
may not be used to supply the holding brake (refer to the Fig. "Recommended circuit for the
external power supply with protective circuit").
