2.1 Before InstallationPlease read the following precautions before installing the VPS.Installation PrecautionsThe VPS should be wall-mounted. Improper placement of the system may result in malfunction, noise, ordiscoloration. Avoid installing the VPS in the following places:• in direct sunlight; in hot, cold, or humid places• in areas where sulfuric gas can damage the equipment (e.g., areas near thermal springs, etc.)• where shocks or vibrations are frequent or strong• in dusty places or places where water or oil may come in contact with the unit• near high frequency generating devices such as sewing machines, elevators or electric welders• on or near computers or other office equipment, microwave ovens, or air conditioners (Ideally, the VPSshould not be installed in the same room with any of these items, and should be at least 2 m (6 ft. 7 in.)away from televisions.)Do not obstruct the areas around the PBX and the VPS. Both require open space above the unit for coolingand space on the sides for maintenance and inspection.Wiring PrecautionsBe sure to follow these instructions when wiring.• Do not wire the telephone cable parallel to an AC power source, computer, etc. If cables are run near thosewires, shield them with metal tubing or use shielded cables and ground the shields.• Use protectors if running cables on the floor. Avoid running cables under carpets.• Avoid sharing the power supply to the VPS with computers or other office equipment. Induction noise fromsuch equipment may interrupt the VPS operation.When making any connections or removing the cover, be sure the power switch is turned off.When installing telephone wiring, basic safety precautions should always be followed to reduce the risk of fire,electric shock and injury to persons, including the following:• Never install telephone wiring during a lightning storm.• Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected atthe network interface.• Use caution when installing or modifying telephone lines.Note• If you live in an area that has frequent power failures, we strongly recommend connecting the VPS andPBX to an uninterruptible power supply (UPS). Use only a UPS which can provide adequate powersupply to all connected devices. Refer to the specifications for the power rating of your VPS and PBX.34 Installation Manual Document Version 3.0 2010/062.1 Before Installation
