6.3 ELECTRICAL CONNECTIONS
Electrical connections should be made by referring to the connection diagram; in cases where cer-
tain of the circuits (communication, block, or others) are not used, the relevant connections must
remain open. Examples of connection diagrams are reported on Appendix to this manual.
For the A1...A22 connections, screw terminals with following characteristics are available:
Nominal cross section: 0.14...2.5 mm
2
(AWG 26...16) for single conductor
da 0.14 a 0.75 mm
2
for two conductors with same cross section
Tightening torque: 0.5-0.6 Nm
Stripping length: 8 mm
For the F1...F5 (RS485) connections, screw terminals with following characteristics are available:
Nominal cross section: da 0.2 a 2.5 mm
2
(AWG 24...12) for single conductor
da 0.2 a 1.5 mm
2
for two conductors with same cross section
Tightening torque: 0.5-0.6 Nm
Stripping length: 10 mm
Traditional CTs inputs
The connections to the current signal inputs C1...C8 can be made by ring lugs suitable for M4 screws
and an insulating panel covering the terminals may be mounted for safety purposes.
LPCTs inputs
The connections to the current signal inputs L1...L3 must be made by RJ45 plugs coupled with LPCT cables.
