Evada User Manual DPS-A (6-10KVA) 205V_V1.1-rev2 ENG

Safety Instructions and PrecautionsThe DPS fully meets the equipment safety requirements of the operating area. DPS and battery modules contain dangerous voltages inside, but they cannot be touched by non-maintenance personnel. The possibility of exposure to high voltages is minimized as components with dangerous voltages can only be accessed by removing the protective cover with a tool. If the equipment is operated according to the general regulations and according to the procedures recommended in this book, there will be no danger. 1. Safety instructions1) There are no user-operable parts inside the distributed power supply (DPS), pleasedo not open the DPS cover without authorization, otherwise there will be a risk of electric shock, and the resulting DPS failure is not covered by the warranty. 2) The distributed power supply (DPS) contains a battery module, even if it is not connected to the AC mains, there may still be voltage at its output. 3) When the DPS needs to be moved or re-wired, the mains input and battery input must be cut off, and the DPS must be completely shut down. Otherwise, there may still be electricity at the output terminal, and there is a risk of electric shock. 4) In order to ensure personal safety and ensure the normal use of the UPS, the UPS should be reliably grounded before use. 5) When DPS is applied to IT power distribution system, a short-circuit protection device must be installed on the neutral line. 6) The use environment has a certain influence on the service life and reliability of DPS. Therefore, please pay attention to avoid long-term use of DPS in the following working environments: ●High, low temperature and humid places exceeding the technical specifications (temperature: 0 ℃ ~ 45 ℃, relative humidity: 0 % ~ 95 %) ●Places exposed to direct sunlight or near heat sources ●A place subject to vibration and easy to be hit ●Places with dust, corrosive substances, salt and flammable gases 7) Please keep the air inlet and outlet of DPS unobstructed. Poor ventilation will cause the temperature inside the DPS to rise, which will shorten the life of the internal components of the DPS, thus affecting the life of the DPS. 8) Do not allow liquid or other foreign objects to enter the DPS case. 9) In case of fire around, please use a dry powder fire extinguisher, if you use a liquid fire extinguisher, there is a danger of electric shock. 10) The output cable of DPS shall not be greater than 10m.2. Precautions for host maintenance1) Do not disconnect the grounding cable of the distributed power system (DPS) or the grounding cable of the building system, otherwise the protective grounding of the distributed power system (DPS) and the connected load will fail. 2) The distributed power system (DPS) is characterized by its own internal battery, so even if the distributed power system (DPS) is not connected to any building wiring system, its output terminal block may still be charged. 3) If you want to disconnect the distributed power system (DPS), please press the key first, and then disconnect the main power supply. 4) Prevent any liquid or other foreign matter from entering the distributed power system (DPS).3. Battery precautions1) It is forbidden to reverse the positive and negative poles of the battery pack, or directly insert the battery
