Before installing the UPS, consider the environmental conditions and avoid installation in areas with high temperature, humidity, or dust.
1-4 Operation
Do not disconnect the mains cable from the UPS system or the building wiring outlet (shockproof socket) during operation. This would disable the protective grounding of the UPS system and all connected loads.
The UPS system features its own internal current source (batteries). The UPS output sockets or terminal blocks may still carry electrical charge even if the system is not connected to the mains.
To fully disconnect the UPS system, press the OFF/Enter button to disconnect it from the mains.
Prevent liquids or other foreign objects from entering the UPS system.
1-5 Maintenance, service and faults
The UPS system operates with hazardous voltages. Only qualified maintenance personnel should perform repairs.
Caution Risk of electric shock: Even after disconnecting the UPS from the mains, components inside the system remain connected to the battery and may still carry live, dangerous voltage.
Before performing any service or maintenance, disconnect the batteries and verify that no current or hazardous voltage is present at high-capacity components, such as BUS capacitors.
Only individuals familiar with batteries and the necessary safety precautions should replace or handle batteries. Unauthorized persons must be kept away from the batteries.
· Caution Risk of electric shock: The battery circuit is not isolated from the input voltage, and hazardous voltages may exist between the battery terminals and ground. Always verify that no voltage is present before touching.
Batteries can cause electric shock and have a high short-circuit current. Please take the following safety precautions when working with batteries:
Remove wristwatches, rings, and other metal objects.
Use only tools with insulated grips and handles. When replacing batteries, ensure that the same number and type of batteries are installed. Do not dispose of batteries by burning them. This could result in a battery explosion. Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes and may be toxic.

5. Storage and Maintenance
Operation
The UPS system contains no user-serviceable parts. The batteries have a service life of approximately 3 to 5 years at an ambient
temperature of 25°C. After this period, the batteries must be replaced. Contact your dealer for battery replacement recommendations.
Be sure to deliver the spent battery to a recycling facility or ship it to your dealer in the replacement battery packing material.
Storage
Before storing the UPS, charge it for 5 hours. Store the UPS covered, upright, and in a cool, dry location. Recharge the battery according to the storage temperature and frequency listed
below.

Emergency Power-off (EPO) (Optional) The Emergency Power-off (EPO) function is designed for situations where it is necessary to shut down the UPS and its load from a remote location. This feature can be used to shut down both the load and the UPS during emergencies, such as overheating. When the EPO is activated, the UPS will:
Shut down the output: All power to the connected devices is immediately cut off.
Shut down power converters: Stops all internal power conversion processes within the UPS.
Remain on: The UPS will continue to stay powered, but in an alarm state to signal the fault condition.
EPO Connections
EPO Activation: Depending on the configuration, the UPS will either run or shut down when the EPO connector pins are either shorted or opened.
To Restart: Reconnect (or re-open) the EPO connector pins and manually turn the UPS back on.

Test EPO Function: It is recommended to test the EPO functionality before applying critical loads to the UPS to avoid accidental shutdowns.
Connector Installation: Even if the EPO function is not needed, leave the EPO connector in place on the EPO port to prevent accidental activation.
Load Segments (Optional) Load segments refer to groups of UPS output receptacles that can be controlled separately through power management software or the UPS display. These segments allow for the controlled shutdown and startup of equipment, which is particularly useful during power outages to conserve battery power.:
Segment 1: Customizable Power Shedding: The battery voltage at which Segment 1 shuts down can be set using the UPS’s LCD interface. This enables users to manage when to cut power to certain non-essential devices based on the battery’s remaining charge. Reference: Check the Battery EOD (End of Discharge) voltage setting for Segment 1 through the UPS’s LCD display to adjust this configuration.
Segment 2: Pre-set Power Shedding: Segment 2 automatically shuts down when the battery reaches the end of its discharge cycle (EOD). This setting is not customizable, but it ensures non-critical devices are powered off as the battery approaches full depletion, preserving energy for essential equipment.
This feature allows for efficient battery management, ensuring that critical systems remain powered while less important devices are safely powered down during outages.
