• Do not stack up the optional service boards.
Wiring Precautions
Be sure to follow these precautions when wiring:
• Do not wire the telephone cable in parallel with an AC power source, such as a computer,
fax machine, etc. If the cables are run near those devices, shield the cables with metal
tubing or use shielded cables and ground the shields.
• If the cables are run on the floor, use protectors to prevent the wires from being stepped
on. Avoid wiring under carpets.
• Avoid using the same power supply outlet for computers, fax machine, and other office
equipment to avoid induction noise interruption when using the SBX IP 320 near other
machines.
• The power and battery switches must be OFF during wiring. After wiring is completed,
the power switch may be turned ON.
• Incorrect wiring may cause the SBX IP 320 System to operate improperly. If an
extension does not operate properly, disconnect the telephone from the extension line and
then re-connect, or turn the System power OFF and then ON again.
• Use twisted pair cable for connecting CO lines.
