Generic rules : ground loop Minimize ground loop areas : cables must be as close as possible from earthed metallic part Series 20 Series 40 Series 80 A ground loop results from the area between an active conductor and the ground.

Generic rules : I/O Series 20 Series 40 Series 80 Outgoing and incoming I/O cables must be together Series 20 Series 40 Series 80 Shielded cables are grounded at both ends (only if both sides are equipotent by an other way !!!) Free conductors in cables must be earthed at both ends Unused input must be shorted to earth

Cubicle prerequisite Switchgear must be connected to building earth Every metallic parts of cubicle, including doors, must be connected together and to earth by wide conductor on non paint parts Series 20 Series 40 Series 80 CTs and VTs secondary common point should be connected to main earth terminal (rectangular copper bare) of cubicle in MV compartment LV compartment should also have a main earth terminal directly connected to the LV compartment one and on witch each equipment should be connected

Power supply requirements Series 20 Series 40 Nominal range : 24 / 250 VDC or 110 / 250 VAC (47.5 / 63 Hz) Absolute range ( -20 / +10% ) : 19.2 / 275 VDC or 88 / 275 VAC Series 80 accept only DC voltage supply Nominal range : 24 / 250 VDC Absolute range ( -20 / +10% ) : 19.2 / 275 VDC Focus on DC supply : Rectified only should not be used because it will reduce lifetime Acceptable ripple content on DC voltage : 12% Series 80
