This manual references the various parts of your UPS by number. INSTALLATION INSTRUCTIONS 1. Unpack unit and check contents. There should be one UPS, two CEE-22 output cables, and one User's Manual.
5. After charging, shutdown both the UPS and load equipment and unplug them from the AC supply socket. Connect the supplied CEE-22 output cable (B) between the load equipment input socket (D) and one of the UPS AC output sockets (E). Connect all load equipment to UPS in this way. 6. When all equipment is plugged in, plug UPS into the AC supply socket and turn it ON. The UPS is ready for normal operation. OPERATING INSTRUCTIONS 1.
COMPUTER/LAN INTERFACE (400/600 VA ONLY) Optional SiteNet 1 kits provide connection to a wide range of popular computer operating systems; such as Novell, UNIX, UNISYS, SUN, WINDOWS and many others. SiteNet 1 software automatically performs an orderly shutdown of computer operating systems, in the event of a power outage and/or low battery conditions. The SiteNet 1 kit supplies a cable to connect supported computer systems to the UPS communications port (10). The table below shows connector details.
Option Switch 3 & 4: Low Voltage Limit Select – Low voltage limit is the voltage level at which battery operation starts. You may set the low voltage limit of the UPS to 180V, 190V, or 200V. The factory setting is 190V. This option reduces excessive battery usage in brownout conditions. Make sure your computer equipment can operate at 180 VAC before selecting the lowest limit (most will).
To Replace the Battery: 1. Close active programs and turn off computers. Turn OFF the UPS and unplug it from mains supply. 2. Place UPS on its side and remove retaining screws (A) to battery door (B). 3. Open battery door (B) and remove the battery (C) by pulling on the battery tab (D). 4. Remove terminal wires (E) from old battery. Connect terminal wires (E) to new battery (C); the red connects to the positive terminal, the black connects to the negative. DO NOT reverse terminal connections.
PROBLEM UPS will not start CAUSE SOLUTION Input voltage below threshold Wait until mains voltage rises to appropriate level. Overload/Short Circuit Check circuit breaker at rear of UPS (9). If it is activated, reset it and restart the UPS (See "Resetting Circuit Breaker'). If problem persists, disconnect some of the equipment from UPS - the total wattage or all your equipment may exceed the capacity of the UPS. If it still will not start, check your computer equipment for short circuits.
