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
