Figure 6-5. Input connections
SDM-SIO2R connections to serial devices are made via the terminals arranged along the top of
the unit. The terminals are spring loaded providing an easy and reliable method of connection.
Strip wires 7 to 9 mm and twist. Open the clamp by pushing the orange tab down with the tip of a
small flat-blade screwdriver and insert the wire into the round hole. Release the clamp and verify
the clamp grips the wire rather than the plastic insulation. See
Figure 6-6. Serial and switched power connections
If there is a need to insert more than one wire in each terminal, if using multi-strand wire, twist
the conductors together first. If using solid wires, solder or crimp multiple pairs together before
insertion.
Ferrules can be used for connections.
