3. Clean earth-ground connection (less than 5 ohms) enhances noise rejection and provides a clear/safe path for

surge currents.

Prepare the network cable for connection to the MX terminal block as follows.

CAUTION: a Strip stranded conductors carefully; do not damage the strands. This will weaken the conductor. Do

not nick conductors or conductor insulation when stripping away the insulation. Nicking stresses the conductor

and can cause the conductor to break. This type of damage may not be apparent and failure can occur later

without warning.

NOTE: Multi-pair cables should provide shielding for each conductor pair.

NOTE: Excess cable should be cut, not coiled or looped, to prevent noise induction into the network and to reduce

signal loss through unnecessarily long cable runs.

Cable Preparation

1. Remove two to three inches (5 to 8 cm) of the outer plastic jacket as shown in Figure 3.2.
