Differential Protection Topology
Protection Data Interfaces
1)
Laser class I acc. to EN 60825-1/ -2 using glass fibre 62.5/125
µ
m
2)
Laser class 3A acc. to EN 60825-1/-2
3) For direct connection, a suitable optical attenuator should be used to ensure trouble-free functioning and to avoid
damage to the device.
Protection Data Communication
Number of devices for a protected object (=number of
ends of the protected zone limited by CTs) 2 for 7SD5*2
2 to 6 for 7SD5*3
Number 1 or 2
- Connection of optical fibre cable Mounting location „D“ for one connection or „D“ and „E“ for two
connections
For flush mounting housing On the rear side
For panel surface mounting housing In console housing at device bottom
