Fig. 5.5 (overleaf)
Warning. Before making
any connections, ensure that the
power supply, any powered control
circuits and high common mode
voltages are switched off.
Note. If it is not possible to
avoid strong electrical and magnetic
fields, screened cables within
earthed metal conduit must be used.
