Bei Verwendung von Sicherungsautomaten muss der Anlaufstrom (I
A
) des Motors
beachtet werden (siehe elektrisches Datenblatt). Wir empfehlen für
Sicherungsautomaten die Auslösecharakteristik D oder K nach IEC 60947-2. Für
die Absicherung von Steuerungen mit Thyristoren empfehlen wir Schmelzsicherungen
statt Sicherungsautomaten zu verwenden, der Einsatz von Sicherungsautomaten
ist aber grundsätzlich zulässig.
For actuator controls equipped with a heating system and external electronics power
supply, the fuses for the heating system have to be provided by the customer (refer
to wiring diagram F4 ext.)

Safety standards
Safety measures and safety equipment must comply with the respectively valid
national on site specifications. All externally connected devices shall comply with
the relevant safety standards for the place of installation.

●
We recommend using connecting cables and connecting terminals according
to rated current (I
N
) (refer to motor name plate or electrical data sheet).
●
For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
●
Use connecting cable with appropriate minimum rated temperature.
●
For connecting cables exposed to UV radiation (outdoor installation), use UV
resistant cables.
●
For the connection of position transmitters, screened cables must be used.
Cable installation in ac-
cordance with EMC
Signal and fieldbus cables are susceptible to interference. Motor cables are
interference sources.
●
Lay cables being susceptible to interference or sources of interference at the
highest possible distance from each other.
●
The interference immunity of signal and fieldbus cables increases if the cables
are laid close to the earth potential.
●
If possible, avoid laying long cables and make sure that they are installed in
areas being subject to low interference.
●
Avoid parallel paths with little cable distance of cables being either susceptible
to interference or interference sources.
Profinet cables
The following minimum requirements with regard to LAN cables apply for Profinet
networks: Category 5 according to ISO/IEC 11801 Edition 2.0 Class D.
