Connecting the power supply module

The wiring from the cubicle terminal block to the IED terminals (see Figure
diagram) must be made in accordance with the established guidelines for this type of equipment.
The auxiliary power wiring should have a minimum cross-sectional area of 1.0 mm
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.
