Connection To Remote Mount Design; Cutting The Signal Cable To Length And Terminating It - ABB VortexMaster FSV430 Commissioning And Safety Instruction

5.6.7

Connection to remote mount design

The signal cable connects the measuring sensor to the
transmitter. The cable is fixed to the transmitter, however, it
can be separated as needed.
When laying the signal cable, observe the following points:
— Install the signal cable in the shortest path between the
measuring sensor and the transmitter. Shorten the signal
cable accordingly as needed.
— The maximum permissible signal cable length is
30 m (99 ft).
— Avoid installing the signal cable in the vicinity of electrical
equipment or switching elements that can create stray
fields, switching pulses and induction. If this is not
possible, run the signal cable through a metal pipe and
connect this to operational ground.
— Carry out all terminal connections carefully.
— Lay the wires in the terminal box in such a way that they
are not affected by vibrations.

Cutting the signal cable to length and terminating it

The signal cable is available in four standard lengths: 5 m
(16.4 ft), 10 m (32.8 ft), 20 m (65.6 ft) and 30 m (98.4 ft).
The cable ends are already prepared for installation.
