When working on the station side of the interface:

Q

AC and DC power may be present with the cabinet. It is used to power 
communications equipment and environmental equipment. Since this 
equipment is energized on a full period basis, normal working 
procedures for powered circuits and devices should be followed when 
working on these same circuits and devices.

Q

Communication pairs that leave the cabinet can be energized at any 
moment. Therefore, rubber mat and rubber gloves should be utilized at 
any time when there is a potential for contact with an energized 
conductor.

Q

Do not install or work on these circuits or cables during a lightning 
storm. Power substations and their transmission systems attract 
lightning due to their designed aerial ground wires above the substation 
grid and support structure.

 

Q

A rubber safety mat and rubber safety gloves must be available for use 
at the job site at all times. These gloves and mat should be tested for a 
10,000 V exposure safe level.
