4.2.1 Protections
The necessary protections depend on the type of installation and the local regulations.
In the case of both DC and AC power supply, it is necessary to provide the safety protections for both DC side and AC side.
For the DC side it is recommended to use a DC switch with current protection (fuses) and surge protection (surge arrestor).
For the AC side, it is advisable to use a fuse or circuit breacker protection with a characteristic curve of type C and a type B
residual current device, sensitive to both AC and DC current.
4.2.2 Electromagnetic compliance
To ensure electromagnetic compatibility (EMC) of the system, it is necessary to apply the following measures:
Always connect the device to ground.
Use shielded signal cables by placing the screen at one end using the EMC clips.
Use motor cable as short as possible (<1 m / <3 ft). For longer lengths, it is recommended to use shielded cables
connecting the screen at both ends.
Separate signal, motor, and power supply cables.
In order to respect limits of EN61800-3 Category C1 for irradiated disturbs, it is necessary to add a ferrite on input phases L
and N. The ferrite and cabling instructions are available on request.
