PWS alarm threshold setting
The IED has power supply module (PWS) at the far left slot. The user can confirm DC rated
voltage on the hardware nameplate by checking the cord at Positions ‘8’, but the user should
select either alarm thresholds for dropping DC voltage by inserting a jumper on the PWS
(Figure 13.5-1). See
Section Power supply module
in
Chapter Technical description
.
DC rated voltage, e.g., 1=’110 to 250Vdc’, selected by the ordering

CAUTION
Note: A short-wire is connected between terminal screws No. 35–37 ( No.35–36 for type
using the ring terminal). It is done by the manufacturer. The user shall remove
that when the user undertakes the dielectric voltage test for the IED; and the user
shall connect again the terminals with that after the test (See
Appendix: Notes for
the dielectric voltage test
).
