CAUTION!
If there is excessive vibration in the process pipework, you must isolate the meter from its
mounting. It is recommended that you place an insert made from rubber (or similar material)
between the meter body, or pipework, and the mounting clamp or fi xing point. For more
information, contact the manufacturer.
Danger:
• Turn off the power supply before working on electrical connections.
• Check the voltage data on the nameplate
• Observe national regulations for electrical installations
• The device MUST be grounded in accordance with regulations to protect personnel
against electric shock
Vibration from pumps and other equipment in the process line can have an eff ect on the meter that, in
some situations, can cause damage. Damage is most likely to occur if the meter has hygienic
connections and the level of vibration is excessive.

Signal cable preparation
The signal cable is made up of fi ve (twisted) pairs of cables. Each pair also has a drain wire and the
three wires are covered in a foil wrap. The fi ve cable pairs are covered in an outer foil wrap and a braided
screen. The complete cable is protected by a PVC outer sheath
1 Outer Sheath
2 Braided screen
3 Outer foil wrap
4 Foil wrap
5 Cable pairs
6 Drain wires
Strip back all the foil wraps and discard them. Unwrap the braided screen so that it can be twisted to form
a connection underneath the earth clamp. Bend all fi ve drain wires back and twist them together with the
braided screen.
It is important that ALL fi ve drain wires AND the braided screen form part of the shielding.
