Cable Extension - HBM P3MB Montageanleitung

NOTE:
If the measurement chain has no other connection to ground, earth or
mains, its zero potential can be connected to the transducer ground, by
soldering an insulated, flexible stranded wire from the cable shield to
socket Y in the HK6S cable socket.
To open the KH6S cable socket HK6S, loosen the clamping bolt
(14 a.f.) from the sleeve (15 a.f.) and pull the socket assembly together
with the cable backward out of the sleeve.
The cable can then be pushed forward through a slit clamping sleeve and
the spacer with the seal, until the soldering tags and the cable shield are
accessible.
When removing the cable socket, please do not pull on the white socket
assembly.

5.1 Cable extension

Extension cables must be shielded and of low capacitance. The supply lines in
particular should have large cross‐sections.
HBM recommends and supplies extension cables and measurement cables by
the meter.
With cable extensions, you must make sure that there is a proper connection
with minimum contact resistance and good insulation between leads and
ground. This is why all the connections should be soldered, made at least with
secure, stable terminals and given a waterproof routing. In the open air and in
a damp environment, the terminal boxes should be encapsulated.
If ordered so that is already a longer cable attached to the transducer when it
leaves the factory, then this, like the 3 m long standard cable is included in the
calibration.
Measurement cables should not be routed parallel to power lines and control
circuits (in shared cable pits, for example). If this cannot be avoided, protect
the measurement cable with a rigid steel conduit and keep it at least 50 cm
away from the other cables. Avoid stray fields from transformers, motors and
contact switches.
