• 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.
