Operation Manual
The wiring from the cubicle terminal block (station battery) to the DC/DC
converter must be made in accordance with established standards for this type of
equipment. Wiring from the DC/DC converter to the SAM600 module uses a 3-pin
connector. For details on wiring diagrams, see
Table 1 .
Power supply connectors
Each SAM600 module has two power supply connectors (X1 and X2). This allows
to connect the SAM600 modules to individual power supply units. The two
connections X1 and X2 are module internally decoupled to support power supply
redundancy.
The connectors accept conductors with a cross section area of 0.2-2.5 mm2 (AWG
24-14,
Section 7.2.2 ). The conductors can be of rigid type (solid, stranded) or of
flexible type. The fastening screw shall be tightened with a torque of 0.4 Nm.
The wires shall be connected to the connector before it is plugged into the SAM600
module, where the connector is then securely tightened with the two screws on
each side of the connector.
4.5 Communication wiring
SAM600 modules exchange information through the SAM600 system bus and
provide IEC/UCA 61850-9-2LE process bus traffic through their IEC 61850 access
points. Synchronization to external source can be achieved by 1PPS or IEC/IEEE
61850-9-3 (PTP). For details on wiring diagrams, see
Table 1 .
Setting up electrical communication
Use Category 5 SFTP cable for electrical communication wiring inside the cubicle.
Electrical Ethernet cabling is only allowed inside the boundaries of an individual
electrical cubicle or kiosk. It is not allowed to interconnect SAM600 modules
between different cubicles using electrical Ethernet cable.
Setting up optical communication modules (SFP)
Use below recommended fiber optical cables for SAM600 system installations and
communication wiring:

Glass fibers with gradient index and LC connector (for 62.5/50 µm optical
fibers)

Diameter of core 62.5/50 µm, sheath 125 µm

Maximum permissible attenuation ≤ 8 dB/6dB

Rodent protected and longitudinally waterproof if in cable ducts
