System Ground
It is strongly recommended that the system be grounded by connecting a heavy, insulated copper wire (e.g.,
14AWG or larger) between the grounding bolt on the right-lower side of the cabinet and an earth ground. Without
this System Ground there is no protection against lightning damage to Co lines and warranty will be voided.
Do not connect the grounding wire of the KSU to a computer, telex, or any other external device.
Connecting Stations
The station cabling for the TD-1648i/TDS-600 should be a home run from the jack to the telephone room. The
termination should be at conventional 66 type connecting blocks or Krone or directly to the provided station
connectors. One pair twisted wiring is required for each station location. Attention to proper cabling will go a
long way towards a successful installation and minimizing service calls after installation. Some guidelines for
running station cable are as follows:
 Avoid running cable parallel to fluorescent light fixtures or electrical lines not in conduit. If these obstacles
are unavoidable, run the cable at right angles across them.
 Do not run station cable inside conduit already occupied by electrical wiring.
 Do not run station cable near equipment with electric motors or strong magnetic fields.
 Do not place station cable on the ground where it can be stepped on or rolled over by office furniture or
office equipment.
