This article introduces the maintenance of UPS equipment, covering power module, STS control module, battery module and air filter maintenance and replacement of the steps, hope to be helpful to the user. Note: 1, can only by the technical personnel of, STS control module, power module and battery module for maintenance. 2, in removing the power module, STS control module, and the battery module, sequence should be from the upper to the lower implementation, to avoid dumping cabinet due to focus on the high side. 3, based on safety considerations, before conducting operation power module and the bypass module, with three meter was used to measure and confirm the dc bus capacitor voltage is lower than 60 VDC. And job target device of peak voltage lower than 60 VDC or 42 of danger. 4Vac。 4, the static switch module does not support hot insertion. Only in the UPS equipment in maintenance bypass mode or turned off completely, can only for static switch module replacement. 5, power module and the bypass module after removed, should be placed for 5 minutes, then maintenance; Wait 10 minutes after completion of maintenance, can only put back inside the cabinet. One, power module replacement steps to confirm the UPS equipment is in normal operation mode and the bypass function and bypass the power supply are available. 1, on the control panel, enter & other; 菜单( Menu) ” → 控制→ 转向绕过→ YES, the manual closed inverter/converter and make the UPS equipment into the bypass mode. 2, to replace the power module standby switch switch to the lock position. 3, wait for two minutes later, the module fixed on either side of the front panel screws removed, the module by the cabinet. Note: the module on the left side of a metal safety clasp, module to half will be the safety clasp to resist cannot extract. At this point, the workers must will withhold the security, to smooth out the module rack. 4, after finish the maintenance module, make sure the module of DIP switch setting correctly and standby switch switch to the standby position. 5, push the module into the cabinet, and a fixed screw to tighten fixed on both sides by the front. If there is not only a power module needs to be installed, the installation time should be between two interval of 10 minutes. 6, wait for two minutes later, the standby switch switch to the lock position. Next, after a few seconds, the module will automatically add system loading. 7, through the control panel and LCD screen, press manual→ 控制→ 上systemturn→ YES, two seconds into the inverter model. Second, the STS control module maintenance steps to confirm the UPS equipment is in normal operation mode and the bypass function and bypass the power supply are all available. 1, through the control panel and LCD screen, press menu→ 控制→ 转向绕过→ YES, the manual closed inverter/converter and make the UPS equipment into the bypass mode. 2, open the power switch, and shut down maintenance bypass switch. 3, wait for two minutes later, the module fixed on either side of the front panel screws removed, the module by the cabinet. 4, the module for maintenance, after the completion of the module into fixed on either side of the cabinet and tighten screw. 5, the bypass switch opening and maintenance, and close the power switch. 6, through the control panel and LCD screen, press manual→ 控制→ 上systemturn→ YES, two seconds into the inverter model. Three, battery module replacement of step 1, disconnect the battery module of each input connector. 2, the module fixed on either side of the front panel screws removed, the battery module by the cabinet. 3, push the new battery module into the cabinet, tighten the screw on both sides of the front panel. Each of the 4, the battery module input connector connected.
