Electrical connection
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 measuring chain are to be connected to the same
earthed conductor.
• The screen of the connection cable is connected to the transducer housing.
6.2 Wiring pin assignment
The 3m long transducer connection cable has colour-coded free wire ends.
The cable shielding is connected in accordance with the Greenline concept.
This means that the measurement system is surrounded by a Faraday cage.
Electromagnetic interference will not affect the measurement system.
Connectors to CE standard are to be fitted at the free end of the transducer.
The shielding is here to be laid over the whole area.
If a different connection technique is used then good EMC shielding is to be
provided in the wiring loom, the shielding again being laid over the full area
(see also HBM Greenline Information, document G36.35.0).
