Wiring the Redundant Power Inputs

STEP 1: Insert the negative/positive DC wires

into the V

-/V+ terminals.

STEP 2: To keep the DC wires from pulling loose,

use a small

flat-

blade screwdriver to tighten the

wire

-clamp screws on the front of the terminal

block connector.

STEP 3:

Insert the plastic terminal block

connector prongs into the terminal block

receptor, which is located on the ICF

-1280I

’s top

panel.

ATTENTION

Before connecting the ICF

-1180I

to the DC power inputs, make

sure the DC power source voltage is stable.

You should also pay attention to the following:

• The temperature rating of the input connection cable should be higher

than 91°C.

• The cross sectional area of the ground wire should be at least 3.31

• The terminal block plug should be suitable for 28-12 AWG

(0.0804-3.31 mm

) wire and a torque of 4.5 lb-in.
