User manual INFOSEC E4 5000 VA

[. . . ] Operating procedure for connecting the long backup time model UPS with the external battery. For transportation only use the original packaging (to protect against shock and impact). Condensation may occur if the UPS system is moved directly from a cold to a warm environment. Do not install the UPS system where it would be exposed to direct sunlight or near heat. [. . . ] C) Connect the external battery cable to the battery first (do not connect the cable to the UPS first, you may encounter hazards of electric shock). The positive pole of the battery is connected to the E4 10000S in parallel with blue and brown wires; the negative pole of the battery is connected to the E4 10000S in parallel with black and white wires; the green and yellow ribbon wire is connected to the ground of the battery cabinet. To complete the connection plug the connector of the external battery cable into the external battery outlet at the back of the UPS. Then switch the breaker of the battery pack to "ON" position. Blue & brown wires to be connected to the positive pole of the battery pack output Black & white wires to be connected to the negative pole of the battery pack output Outlet to be connected to the UPS Green and yellow wires to be connected to the ground of the battery pack N represents the minimum UPS number that the total load needs; X represents the redundant UPS number, i. The bigger the X is the higher the reliability of the power system will be. As long as the UPS is equipped with parallel cables, up to 3 UPS can be connected in parallel to realize output power sharing and power redundancy. Users need to opt for a standard 25-pin communication cable, which should have 25 cores, corresponding stitches and shield, as the UPS parallel cable. Strictly follow the stand-alone wiring requirement to perform the input wiring of each UPS. Disconnect first the Jumper between JP1 and JP2 then connect each input breaker to a main input breaker and each output breaker to a main output breaker and then to the loads. When the distance between the UPS in parallel and the breaker panel is less than 20 meters, the difference between the wires of input & output of the UPS is required to be less than 20%. When the distance between the UPS in parallel and the breaker panel is greater than 20 meters, the difference between the wires of input & output of the UPS is required to be less than 10%. Note: the units switch to "INVERTER" mode simultaneously as they start up one by one in utility power mode. When the last unit turns of, each UPS simultaneously shuts down the INVERTER MODE and starts working in BYPASS MODE. You just need to read through this manual and carefully follow all instructions. Turn on the UPS with utility power supplied (in Line mode/AC mode) Check power supply connection and switch the input breaker on back of UPS to "ON" position. Ventilation system starts and the UPS supplies power to the load via the bypass ("BY PASS" led lights on). To turn on the UPS press the green "ON" After a few seconds the "INVERTER" led lights on, the "BY-PASS" led lights off and henceforth the UPS is running in Utility Power mode. If the utility power is faulty, the UPS automatically switch to battery mode avoiding any interruption. Turn on the UPS with no utility power supplied (in Battery mode) Button for more than 1 second to power on the UPS. For long backup time model ("S" model), please make sure that the battery breaker is in "ON" position. Starting up process in battery mode is identical to starting up process in AC mode. [. . . ] Complete description of the problem, including the LED display, alarm warning, power condition and load capacity. If your UPS is a long backup time model ("S" version), you may also need to provide the service center with battery information. The "LOAD LEVEL" leds (leds from 6 to 2) switch on in accordance with the load capacity connected (See below Fig 15. It is recommended to get rid of some non-critical loads one by one to decrease the loads connected to the UPS less than 90% of its nominal power capacity. [. . . ]
