The DC power must be connected to a well-fused power supply.
When attaching power wires to the DC terminal block’s power contacts consider:
•
DC terminal block pitch, 5.08 mm
•
Wire size range: Solid wire: 12~24 AWG and Stranded wire: 12~24 AWG
•
Wire length 3 m (9.84 ft.) maximum
•
Wire strip length 7 mm (0.28 in)
With multiple power sources connected to the switch, the switch utilizes the power supply
with the higher voltage or the most stable power supply.
