3-11 Installation and wiring
3-6-3. Sensor cable connections using junction box (BA10) and extension cable (WF10)
Where a convenient installation is not possible using the standard cables between sensors and converter, a
junction box and extension cable may be used. The Yokogawa BA10 junction box and the WF10 extension
cable should be used. These items are manufactured to a very high standard and are necessary to ensure
that the specifications of the system are not compromised. The total cable length should not exceed
50 metres (e.g. 5 m fixed cable and 45 m extension cable). In the case of systems using dual high
impedance sensors (e.g. Pfaudler 18), then the cable length is restricted to 20 metres (fixed cable only, no
extension with WF10).
