5.4 Electrical Connections – Fig. 5.6 (overleaf)
Warning. Before making any connections, ensure that the power
supply, any high voltage-operated 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.
