1. Unscrew the two screws arranged diagonally at the front of each barrier box and use these same screws to reattach
the barrier box to the rack mounting strip.

discard this wire. Connect a green/yellow ground wire to the protective earth screw in the center of the Point on the
back of the Barrier Box.
3. The rack mounting strip has threaded M4 earthing pillars. Connect the other end of the barrier box ground wire, using
M4 washers and nuts, to the earthing pillar on that side of the rack mounting strip.
4. Using 14AWG wire with green and yellow sleeve, connect one of the earthing pillars to the buildings protective earth.
5. Using 14AWG wire with green and yellow sleeve, connect the other earthing pillar to the Phone module.
6. Ensure that the following wires are not routed together in the same bundle:
• Earth lead from the barrier box to the IP400 Phone 8/16/32.
• Internal wires, e.g. wires going directly to the IP400 Phone 8/16/32.
• Wires from external telephone going directly to the barrier boxes.
