Wiring Power Input
NGI-U08C2 with 6-Pin Terminal Block
Use “PWR” for Primary Power input and “RPS” for Redundant Power
input. The top view of Terminal Block is shown in the figure below:
Caution:
• Use copper conductors only.
• Use wiring cable with rated temperature at least 221°F
(105°C).
• Tighten the wire to a torque value 4.5 lb•in (0.5 N•m).
• The wire gauge for the terminal block should range between
12~24 AWG (4~0.25 mm2).
To insert the power wire and connect the 24~48VDC at a maximum of
0.4A DC power to the power terminal block:
• Use a flathead screwdriver to loosen the wire clamp screws.
• Insert the negative/positive DC wires into the PWR-/PWR+ terminals,
respectively.
• Tighten the wire-clamp screws to prevent the wires from loosening.
ATTENTION: Use a power supply rated for 24~48VDC.
The device power must be supplied by SELV circuit.
