User manual INFOSEC E4 2000 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. The UPS system must be absolutely dry before being installed. [. . . ] After the installation completed, make sure the wiring is correct. 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. By default the UPS number that the system can handle simultaneously. The bigger the X is the higher the reliability of the power system will be. when reliability is essential , N+X is the optimal mode. 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. The length of the parallel should not be less than 3 m. Strictly follow the stand-alone wiring requirement to perform the input wiring of each UPS. connect the output wires of each UPS to an output breaker panel. 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. SHUTDOWN: turn off all units ones by one (slightly press OFF). When the last unit turns of, each UPS simultaneously shuts down the INVERTER MODE and starts working in BYPASS MODE. It is easy to operate the equipment with no previous training. You just need to read through this manual and carefully follow all instructions. [. . . ] Note: Please follow the following steps to connect the generator Activate the generator and wait until the operation is stable before supplying power of the generator to the UPS (make sure the UPS is in idle mode). Then turn on the UPS according to the start-up procedure. Once the UPS is on, you may connect the loads to the UPS one by one. The power capacity of the AC generator should be at least twice higher than the capacity of the UPS. [. . . ]
