The LEDs of the battery are blinking!   The batteries probably need to be changed. The battery change procedure depends on the size of the system. Please contact us and we will immediately inform you how to proceed.   The UPS system bleeps in long time intervals!   There are two possibilities: either the batteries will have to be changed because their lifespan has come to an end, or the UPS system operates in bypass mode.   The network LED is blinking!   Turn the plug that supplies the UPS with power (phase and neutral).   How can I integrate UPS systems into network systems   Serially over a RS232 interface or via web / a SNMPS card.     We are constantly working to extend this page.
