To ground the IC3000 to earth ground, follow these steps:

Step 1

Use a standard Phillips screwdriver or a ratcheting torque screwdriver with a Phillips head to remove the ground

screw from the front panel of the device.

Step 2

Use a wire stripping tool to strip the16 AWG (1.5mm2) grounding wire to 0.22 in. (5.56 mm).

Insert the ground wire into the ring terminal lug, and using a crimping tool,

crimp the terminal to the wire.

Step 3

Slide the ground screw through the terminal.

Step 4

Insert the ground screw into the functional ground screw opening on the

front panel.

Attach the ring terminal to the chassis using the screw set aside in step 1.

The graphic to the right shows the proper ground connection points.

Step 5

Use a ratcheting torque screwdriver to tighten the ground screw and ring terminal to the IC3000 front panel to 3.5

in-lb (0.4 N-m).

Step 6

Attach the other end of the ground wire to a grounded bare metal surface, such as a ground bus, a grounded DIN

rail, or a grounded bare rack.
