We recommend adapting the switchgear sizing to the max. current (I
and setting the overcurrent protection device in compliance with the indications in
the electrical data sheet.
Version with thermoswitches as motor protection:
According to EN 60079-14, a thermal overcurrent protection device (e.g. motor
protection switch) must be installed for explosion-proof actuators in addition to
the thermoswitches.
Version with PTC thermistor:
PTC thermistors additionally require a suitable tripping device in the actuator
controls.
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 applicable for the place of installation.
We recommend using connecting cables and connecting terminals according
to rated current (I
N
For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
Use connecting cables, cable glands, reducers, blanking plugs with a minimum
temperature range of +80 °C.
To avoid contact corrosion, we recommend the use of sealing agents for cable
glands and blanking plugs made of metal.
For connecting cables exposed to UV radiation (outdoor installation), use UV
resistant cables.
For the connection of position transmitters, screened cables must be used.
The section below provides an overview of the different electrical connections
described in the chapters to follow.
