a sealed environment unless proper ventilation is provided.
• Make sure that the surface behind the PBX is flat and free of obstacles, so that the
openings on the back of the PBX will not be blocked.
• 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 or wall.
• 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 mm²) shall be used.
• 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.
• Make sure to install all necessary optional service cards in the PBX before
performing the wall mounting procedure. If it is necessary to install or remove a
card, make sure to detach the PBX from the wall before installing or removing the
card.
• When placing the PBX onto the wall, make sure that the arrows on the metal
brackets are pointing upward. If the arrows are not pointing upward, the PBX may
fall, resulting in injury.
• When driving the screws into the wall, be careful to avoid touching any metal laths,
wire laths or plates in the wall.
• Before opening the top cover, the AC power cord must be removed from the AC
inlet.
• 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.
• Performing surge protection is essential. Make sure to follow the instructions in the
Installation Manual.
• It is strongly recommended to use SSL encrypted communication when the PC is
accessing the PBX via the Internet. To use SSL encryption, routers must have a
port set up for https communication.
• 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.
• Trunks should be installed with surge protectors.
• When installing or removing the optional service cards, the power switch must be
turned off.
• For earthing wire, green-and-yellow insulation is required, and the cross-sectional
area of the conductor must be more than 0.75 mm² or 18 AWG.
• When connecting a PRI30/E1, PRI23, BRI2 or BRI4 card to the trunk, connect
through an NT1; do not connect to the U interface of the trunk directly.
