Safety Precautions

This device is an indoor unit and therefore, must not be installed outdoors.

Ethernet cabling must be routed only indoors and must not exit the building.

The device must be installed and serviced only by qualified service personnel.

Do not open or dismantle the device.

Do not expose the device to water or moisture.

Make sure the device is installed in a well-ventilated location to avoid over heating of internal

components and subsequent damage.
Do not place any object on top of the device and make sure that sufficient clearance from the top and

sides are maintained to ensure proper airflow to avoid over heating of internal components.
Operate the device in an ambient temperature (Tma) that does not exceed 40°C (104°F).

The device must be installed only in restricted access locations.

The device must be connected permanently to earth via the screw terminal, located on the device's

rear panel, as per the instructions in the device's Hardware Installation Manual.
The grounding connection must not be removed unless all FXS lines are first disconnected from the

device.
Installation of the device must be in accordance with national electrical codes and conform to local

regulations.
AC Power: Use only the supplied AC power cord for connection to the power source.

AC Power: Connect the device to an electrical socket outlet that provides protective earthing

(grounding).
DC Power: Connect the device to a safety extra-low voltage (SELV) source that is sufficiently isolated

from the mains.
The device is immune against power surge levels of up to 1 Kilovolts (KV) as required by the following

standards: IEC 61000-4-5, EN 55024, and EN 300386. Power surges above protection levels as required
by EN 55024 and EN 300386 may cause damage to the device.
The device includes an integrated secondary surge protection, but does not include primary telecom

protection. To comply with ITU-K.21 requirements when the telephone lines are routed outside the
building, it is essential to install additional protection using a three-electrode Gas Discharge Tube (GDT)
rated 350V as a primary protection on the MDF, located at the entrance point of telephone wiring to
the building. The center pin of the GDT must be connected to ground.
For FXS ports, use minimum 26-AWG wiring if it exits the building.
