2. PROPER HANDLING

It is important to exercise the following proper handling procedures when transporting and installing cable.

DO NOT pull the cable from the wrong end; otherwise, the cable will tangle.

— Take care to not drop or crush the connectors.

DO NOT hit the connector ends against any hard surface. Dropping or hitting the connector against a hard surface may result in bending or breaking of the front mating shield.

— Observe and implement proper minimum cable bend radius and pulling tension per TIA-568.

3. INSTALLATION AND REMOVAL GUIDELINES

3.1. Installation

NOTE i

A label marked “KEY”, attached to the plug, indicates the location and orientation of the polarizing key.

DO NOT attempt to overcome the polarizing keys by force.

2. Insert the plug into the receptacle until it bottoms.

CAUTION

Ensure that the plug is fully seated into the receptacle before tightening the jack screws.

Failure to bottom the plug may result in stripping or cross threading of the jack screws.

Tighten each screw to a maximum torque of 0.23 N-m

[2 lbf-in]. DO NOT use an automatic screwdriver.
