    voltages are present within the battery box. However, the risk of contact with these high voltages is minimized for non-service personnel. Since the component with dangerous voltage can only be touched by opening the protective cover with a tool, the possibility of touching high voltage component is minimized.

  • Page 11: Disposal And Recycling

     The batteries are very heavy. Please handle and lift the battery with proper method to prevent any human injury or damage to the battery terminal.  Don’t decompose, modify or damage the battery. Otherwise, battery short circuit, leakage or even human injury may be caused.

    Annex. A Instructions of the parallel system for modular UPS The UPS of 6-slot or10-slot can be paralleled; the general is 2 UPSs in parallel or 3 UPSs in parallel. The UPS of 20-slot cabinet don’t support the parallel, and the 10-cabinet can be paralleled with 3 UPSs at most;...
  • Page 92 The cable connection drawing for 2UPSs in parallel (common input) Note: IS1 and IS2 are the input switches for each UPS, OS1 and OS2 are the output switches, OS is the output main switch of the power system, MBS is the maintenance bypass switch, and all the switched mentioned above need to be provided by users, the UPS has only one manual rotation bypass switch (the manual bypass switch).
  • Page 93 MS1, MS2 and MS3 are the main input switches for each UPS, BS1, BS2 and BS3 are the bypass input switches, OS1, OS2 and OS3 are the output switches, OS is the output main switch of the power system, MBS is the maintenance bypass switch, and all the switched mentioned above need to be provided by users, the UPS has only one manual rotation bypass switch (the manual bypass switch).
  • Page 94 2) To set the parallel board as below The setting for 2 UPSs in parallel Note: J3, J5, J7, J9, J11 and J4 are short-circuited by the jumpers; J6, J8, J10, J12, J13, J14, J15 and J16 are open.
  • Page 95 The setting for 3 UPSs in parallel Note: only J3 and J4 are short-circuited by the jumpers, the other pins are open. 3) To set the parameters on the display screen As long as the display screen is lit, users can set the parallel parameters on the screen. a) To choose the system mode: Parallel.
  • Page 96 4) To check the parameters on the display screen and ensure the parameters are same for each UPS below, if no special requirement, please keep the parameters in the default setting. The setting interface for USER Setting 5) To check the nameplate of each UPS and ensure the model, the rated voltage and the rated frequency same.
  • Page 97 7) To connect the parallel signal cables. The parallel signal cable a) When 2 UPSs in parallel, please operate as below. The signal cable connection for 2 UPSs in parallel b) When 3 UPSs in parallel, please operate as below. The signal cable connection for 3 UPSs in parallel 3.
  • Page 98 Note: Before the operation, please keep all the switches off. 1) First close OS1, and then close BS1 and MS1, the first UPS will start automatically, for the details of start, please refer to the user manual. About 2 minutes later, the first UPS will complete the start and final close the battery switch used with the first UPS.
  • Page 99 The operation interface for transferring to bypass The operation interface for escaping bypass 6) Close the main output switch OS, the system is completed, users can start their equipment one by one. 4. The operations for the parallel system 1) Shut down the UPS. When UPSs in parallel, and if users want to shut down one UPS or all UPSs, there take the parallel system of 3 UPSs with dual input for example, please operate as below.
  • Page 100 First turn off the battery switch used with the first UPS, and then turn off BS1 and MS1 one by one, and finally turn off OS1, the first UPS will be off. If recover, please first turn on OS1, and then turn on BS1 and MS1 one by one and finally turn on the battery switch.
  • Page 101 c) Turn on BS1, BS2 and BS3 one by one, about 20 seconds later, confirm the static bypass of each UPS should be on. d) Turn off the maintenance bypass switch MSB e) Turn on MS1, MS2 and MS3. About 30 seconds later, the rectifiers of all modules should be on. f) Turn on all the battery switches one by one.
