Figure-11.D illustrates external connection around the power supply module (PWS). During dielectric
voltage testing, short-wires and a short-bar attached on the PSW shall be carefully handled; follow
the below instructions (1), (2) and (3).
(1) The short-wire between terminal screw No.35 and No.36
✓ Remove the short-wire for undertaking the dielectric voltage test. If the short-wire is not
removed, the IED will be damaged.
✓ After the test, reconnect the short-wire to the original positons.
(2) The Short-bar between terminal screw No.37 and FG
✓ Never remove the short-bar. If the short-bar is removed, the IED will be damaged.
(3) The short-wire between terminal screw No.38 and FG
✓ Never remove the short-wire. If the short-wire is removed, the IED will be damaged.
