1.1 For Your Safety
•
When relocating the equipment, first disconnect the telecom connection before disconnecting the power
connection. When the unit is installed in the new location, reconnect the power first, and then reconnect
the telecom connection.
•
The power supply cord is used as the main disconnect device. Ensure that the AC outlet is located near
the equipment and is easily accessible.
•
Slots and openings in the front, back and bottom of the cabinet are provided for ventilation; to protect it
from overheating, these openings must not be blocked or covered. The openings should never be blocked
by placing the product on a bed, sofa, rug, or other similar surface while in use. The product should never
be placed near or over a radiator or other heat source. This product should not be placed in a sealed
environment unless proper ventilation is provided.
•
Make sure that the surface behind the PBX is not made of wood.
•
When this product is no longer in use, make sure to detach it from the rack.
•
Use only the AC power cord included with the PBX.
•
A certified power supply cord has to be used with this equipment. The relevant national installation and/or
equipment regulations shall be considered. A certified power supply cord not lighter than ordinary polyvinyl
chloride flexible cord according to IEC 60227 (designation H05VV-F 3G 0.75 mm
•
When the PBX is mounted on a 19-inch rack, make sure that the installation of the unit does not cause the
temperature of the rack to exceed its limit.
•
When opening the top cover, the power switch must be turned off.
•
For safety reasons, close the top cover and tighten the screws before operating the PBX.
•
If the PBX is not installed properly using the securing correct methods, the PBX may fall causing serious
damage.
•
When the PBX is placed on a desktop, make sure that the PBX is placed as indicated in "4.2.10 Placing
the PBX on a Desktop". Do not place it on its side or upside down.
•
Performing surge protection is essential. Make sure to follow the instructions in "4.2.11 Surge Protector
Installation".
•
It is strongly recommended to use TLS encrypted communication when the PC is accessing the PBX via
the Internet. To use TLS encryption, routers must have a port set up for https communication.
•
To prevent data leakage, render the Storage Memory Card physically unusable before disposal.
•
Avoid using the same AC outlet for computers and other office equipment, as noise generated by such
equipment may hamper system performance or interrupt the system.
•
Unplug the system from its power source when wiring, and plug the system back in only after all wiring is
completed.
•
CO lines should be installed with surge protectors. For details, refer to "4.2.11 Surge Protector
Installation".
•
When installing or removing the Storage Memory Card, the power switch must be turned off.
•
When installing or removing the optional service cards, the power switch must be turned off.
•
For grounding wire, green-and-yellow insulation is required, and the cross-sectional area of the conductor
must be more than 0.75 mm
•
When connecting an SLC2/PRI23 card to the CO line, connect through an NT1; do not connect to the U
interface of the CO line directly.
•
The PRI port of the SLC2/PRI23 card is an SELV port and should only be connected to SELV services.
•
The MOH port and Pager port are SELV ports and should only be connected to approved SELV devices.
•
To protect the system, keep the following in mind:
a.
Make sure that both connector cases (frame ground) of the RS-232C cross cable (shielded cable) are
conductive. If they are not conductive, make sure that both connector cases of the cable are firmly
connected.
b.
If this is not possible, connect the frame of the PBX to the frame of the PC/Printer using a grounding
wire in order to prevent difference in the electrical potentials.
