How to use

Install the UPS in a well-ventilated location and connect the mains supply before powering connected equipment. Use the integrated LCD to monitor operational status and battery charge. For normal operation leave the UPS connected to mains so the batteries remain charged; in case of mains failure the unit automatically switches to battery with zero transfer time. For network monitoring or remote control, install an SNMP module in the available slot and connect via the USB or RS-232 port as required. Use the built-in service bypass when performing maintenance to avoid interruption to connected loads.

Usage recommendations

Place the UPS on a stable, level surface with adequate clearance for airflow. Periodically check the LCD for warnings, and test the battery backup under load after installation. Replace batteries according to the manufacturer’s guidance or when backup time noticeably decreases. Do not expose the unit to moisture, excessive dust or temperatures outside the recommended operating range.
