DC Terminal Block
The removable DC terminal block enables the connection of dual external (12 VDC to 58 VDC) power supplies using the
P1+/- and P2+/- contacts (Figure 7, pos. 1 and 2). When dual power sources are connected to the switch, the switch
utilizes the power supply with the higher voltage or the most stable power supply.
When connecting the power follow the polarity indicated for P1 +/- and P2+/-.
When attaching power wires to P1+/- and P2+/- on the DC terminal block consider:
•
DC terminal block pitch, 5.08 mm (0.2 inch)
•
Wire strip length 7 mm (0.28 inch)
•
Wire size range: Solid wire: 12~24 AWG and Stranded wire: 12~24 AWG
•
Wire length 3 m (9.84 ft.) maximum
