1.4. Functioning
• Do not disconnect the power cord of the UPS, otherwise the protection that the earth ground provides to
the UPS and all its loads will be nullied.
• The UPS has its own internal power supply (batteries). There may be voltages at the UPS output socket or
output voltage terminals, even if the UPS is not connected to the mains.
• To completely turn off the UPS, press the OFF/Enter switch.
• Prevent the entry of liquids or foreign objects inside the UPS.
1.5. Maintenance and repair
• The UPS operates with dangerous voltages. Any repair must be carried out exclusively by qualied person-
nel. Do not open or disassemble the UPS in any other case.
• Caution - Risk of electric shock. Even after disconnecting from the grid, the internal wiring is still connected
to the battery and the voltage is dangerous.
• Before carrying out any type of service and/or maintenance, disconnect the batteries, verifying that there is
no current or risk of voltage, including those created by high capacity capacitors.
• Only people authorized to deal with batteries and who do so with the necessary measures and precautions
can replace batteries and control operations.
• Caution - Risk of electric shock. The battery is not isolated from the input voltage circuit. There may be
dangerous voltages between the battery terminals and the ground. Before touching anything, please check
that there is no voltage!
• Batteries can cause electrical shock and short circuits. Please take the precautions detailed below and any
other necessary measures when working with batteries, such as removing watches, rings and other metal
objects, as well as using only tools with insulated handles.
• When changing batteries, install the same number and the same type of batteries.
• Do not attempt to throw away or burn batteries, as they may explode.
• Do not open or destroy batteries. Released electrolyte can damage skin and eyes. The battery is toxic.
• Please replace the fuse only with another of the same type and amperage to avoid risk of re.
Before installation, please
check the drive.
