Instructions for cabling

S Always use shielded, low‐capacity measurement cable, available from
HBM.
S 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).
S Avoid stray fields of transformers, motors and contactors.
S 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.
S The screen of the connection cable is connected to the transducer housing.
Connecting to terminals
► You can get to the screen through a slit in the cable sheath (see page 15).
► Lay the screen flat on the housing frame.
Attaching to a male connector
► Lay the cable shield flat on the connector housing.
