Rack Mount Safety Instructions
When installing the chassis in a rack, implement the following safety
instructions:
•Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly,
consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature (Tma) of 40°C (104°F).
•Reduced Air Flow - Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation on the equipment is not
compromised. Avoid stacking equipment one on top of the other and make sure to
keep the ventilation openings free from cables or any objects to allow free air
circulation.
•Mechanical Loading - Mounting of the equipment in the rack should be such that
a hazardous condition is not achieved due to uneven mechanical loading.
•Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
•Connection to Protective Earth - To avoid injury, electrical shock, and damage
to the device, reliable earthing of rack-mounted equipment should be maintained.
Attention should be given to supply connections other than direct connections to
the branch circuit (e.g., use of power strips.)
To install mount the device in a 19-inch rack:
1. On one side of the chassis, locate the two mounting screws (nearest to the front
panel).
2. Remove the two screws.
3. Insert the peg on one of the brackets into the third air vent down on the column of air
vents nearest the front panel.
4. Swivel the bracket until the holes in the bracket align with the two empty screw holes
on the chassis.
5. Use the supplied screws to attach the bracket to the side of the chassis.
6. Repeat steps 1 through 5 to attach the second bracket to the other side of the chassis.
7. Position the device in the rack and line up the bracket holes with the rack frame holes.
8. Use four standard rack screws (not supplied) to attach the device to the rack.

Hardware Installation Manual 5. Cabling the Device
5 Cabling the Device
This section provides cabling instructions for the device.
5.1 Power Surge Protection and Grounding Connections
This section describes grounding and power surge protection.
Warning:For the AC powered model, ensure that you connect the device to an
electrical socket outlet that provides protective earthing (grounding). Prior to
connecting power, refer to the Regulatory Information on AudioCodes website.
•Finland: "Laite on liltettava suojamaadoituskoskettimilla varustettuun
pistorasiaan."
•Norway: "Apparatet rna tilkoples jordet stikkontakt."
•Sweden: "Apparaten skall anslutas till jordat uttag."
Warning:
•The equipment must be installed only in telecommunication sites/ centers in
compliance with ETS 300-253 requirements “Earthing and Bonding of
Telecommunication Equipment in Telecommunication Centers”.
•Prior to installation, earth loop impedance test must be performed by a certified
electrician to ensure grounding suitability at the power outlet intended to feed the
unit. It is essential that the impedance will be kept below 0.5 ohms!
•Proper grounding is crucial to ensure the effectiveness of the lightning protection,
connect the unit permanently to ground as per the illustration in this section.
•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 as per the illustration in this section.
•Failing to install primary surge protectors, and failing to comply with the grounding
instructions or any other installation instructions, may cause permanent damage to
the device.
•As most of the installation is the responsibility of the customer, AudioCodes can
assume responsibility for damage only if the customer can establish that the
device does not comply to the standards specified above (and the device is within
the hardware warranty period).
•The device complies with protection levels as required by EN 55024/EN 300386.
Higher levels of surges may cause damage to the unit.
Lightning is the transient passage of electrical current between a cloud and the surface of
the earth. Part of the lightning current can be carried inside a building from electrical lines
and analog and/or digital telephone lines located outside. This direct injection of lightning
current inside a building can cause considerable damage to electronic circuits and
equipment.
The device must be installed in the Telecommunication rack. The device's grounding screw
must be connected to the equipotential grounding bus bar located in the

Hardware Installation Manual 20 Document #: LTRT-59850
MP-124
Telecommunication rack, using a wire of 6 mm2surface wire. This line must be connected
to the equipotential bus bar of the electrical circuit board located in the Telecommunication
room, using a stranded cable with surface area of 25 mm2. The length of this cable must
be as short as possible (no longer than 3 meters).
The device chassis is equipped with a protective earthing screw. Ensure that you connect
this to the grounding point using a suitable wire. Fasten the cable securely using a 6-32
UNC screw.
The grounding and lightning protection cabling setup for the device depends on whether
AudioCodes orderable FXS Patch Panel (see Section 5.1.1) or a third-party MDF (see
Section 5.1.2) is used.
