Connecting the power supply module
SEMOD128790-5 v7
The wiring from the cubicle terminal block to the IED terminals (see Figure
for PSM connection
diagram) must be made in accordance with the established guidelines for this type of equipment.
Insert only the corresponding male connector to the female connector. Inserting
anything else (such as a measurement probe) may violate the female connector and
prevent a proper electrical contact between the printed circuit board and the external
wiring connected to the screw terminal block.
The auxiliary power wiring should have a minimum cross-sectional area of 1.0 mm
2
and a voltage
rating of 250 V. Branch circuit protection must be provided in the auxiliary power supply wiring to the
IED, and if necessary it must be possible to disconnect manually from the power supply. Fuse or
circuit breaker up to 6 A and 250 V should be close to the equipment. It is recommended to separate
the instrument transformer leads from the other cables, that is, they should not be run in the same
cable ducts or loom. The connections are made on connector X11.
