Safety standards Safety measures and safety equipment must comply with the respectively valid na-
tional on site specifications. All externally connected devices shall comply with the rel-
evant safety standards for the place of installation.
Connecting cables, cable
glands, reducers, blanking
plugs
• We recommend using connecting cables and connecting terminals according to
the rated current (I
N
). (Refer to Motor name tag [}9] or electrical data sheet.)
• Use suitable (voltage-proof) cables. Specify cables for the highest occurring rated
voltage.
• Use connecting cables, cable glands, reducers, blanking plugs with a minimum
temperature range of 165 °F (+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 re-
sistant cables.
• For the connection of position transmitters, screened cables must be used.
