6.1 Instructions for cabling
• Always use shielded, low-capacity measurement cable (HBM cables meet
these requirements).
• Do not lay measurement cable parallel to high-voltage power lines or
control circuits. If this is not possible (e.g. in cable ducts) protect the
measurement cable, e.g. with armoured steel tube and maintain a minimum
distance of 50 cm from the other cables. High-voltage power lines and
control lines should be twisted (15 turns per metre).
• Avoid stray fields of transformers, motors and contactors.
• Do not earth transducer, amplifier and display device more than once. All
the devices in the measurement chain are to be connected to the same
earthed conductor.
• The screen of the connection cable is connected to the transducer housing.
