Connecting the multiple EBMs C400R-010-B C400R-020-B and C400R-030-B UPS include an external battery port that allows users to connect multiple EBMs in order to provide additional backup time. Follow the procedure to install multiple EBM as below. Connecting multiple EBMs in Tower form 1.
Note: Three or more EBMs can be connected to the UPS in the same way as shown above. Note: After connecting the EBMs please do not forget to set the number of EBMs on LCD (see section 12). 1.2 Operation ...
1.3 Maintenance, servicing and faults The UPS operates with hazardous voltages. Repairs may be carried out only by qualified maintenance personnel. Caution - risk of electric shock. Even after the unit is disconnected from the mains power supply (building wiring socket), components inside the UPS are still connected to the battery which are potentially dangerous.
1.3.2 Storing the UPS and batteries When the UPS is to be stored for a long periods, recharge the battery every 6 months by connecting the UPS to utility power. The batteries charge to 90% capacity in approximately 4 hours. However it is recommended that the batteries charge for 48 hours after long-term storage.

5.2.3 Bypass mode The LCD display in bypass mode is shown in the following diagram. The UPS does not provide a backup function when it is in bypass mode. The power used by the load is supplied from the utility power via an internal filter. The UPS will beep once every 2 minutes in bypass mode.
mode 5.2.5 HE mode (High Efficiency It is also called economy (ECO) mode. After the UPS is turned on the power used by the load is supplied from the utility power via internal filter while the utility power is in normal range so the high efficiency can be gained in the HE mode.
Fig. 5-8 Converter mode The function can be enabled through the LCD setting or the management software (WinPower, etc.). The load should be derated to 70% in converter mode. 5.2.7 Warning When a warning occurs the UPS will display the relevant warning. Most warnings are not fatal and the UPS will continue to work, but they should be paid attention to, otherwise the UPS may fail.
5.2.8 Fault When the fault occurs the UPS will indicate the relevant fault code. Depending on the severity of the fault the UPS will switch to bypass or cease/stop providing an output and give a constant alarm. The backlight of LCD would also turn red.
Fig. 5-12 Battery test If a battery status fault of “bad battery detected” or “battery disconnected” is found, the battery failure symbol will be shown and the UPS will alarm. Fig. 5-13 Battery Fails 5.3 Turning the UPS on and off Attention: The UPS can only be turned on when connecting to the mains input for the first time.
