• Dangerous voltage levels are present within the system. It must only be opened by qualified service personnel. Servicing of batteries must be performed or supervised by personnel who are knowledgeable about batteries and the necessary precautions. • The system must be properly grounded. • The batteries supplied with the system contain small amounts of toxic substances. • There is a risk of explosion if batteries are replaced with an incorrect type. When replacing batteries, replace them with the same type and number of batteries or battery packs. Do not dispose of batteries in fire. Batteries may explode. Dispose of used batteries according to the instructions. Batteries must not be opened or chopped. Released electrolyte is harmful to skin and eyes. It can be toxic. A battery can pose a risk of electric shock and high short-circuit currents. • The instructions for connecting and operating the UPS described in the manual must be followed in the order given. • UPS enclosure protection class IP20. • To reduce the risk of fire, the equipment is only connected to a circuit provided with branch circuit overcurrent protection. • The upstream Normal AC / Bypass AC circuit breaker must be easily accessible. The equipment can be isolated from the AC source by opening this circuit breaker. • An additional AC contactor is used for backfeed protection and must comply with IEC/EN 62040-1 (creepage and clearance distances must meet the basic insulation requirements for pollution degree 2). Disconnection and overcurrent protection devices must be provided by others for permanently connected AC input (Normal AC / Bypass AC) and AC output circuits. • Check that the rating plate information matches your AC system and the actual power consumption of all equipment to be connected to the system. For installation with three-phase AC input, this equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc at the interface point between the user's supply and the public system is greater than or equal to 3.63 MW. It is the responsibility of the installer or user of the equipment to ensure, after consultation with the distribution system operator if necessary, that the equipment is only connected to a supply with a short-circuit power Ssc greater than or equal to 3.63 MW. • For permanently connected equipment, an easily accessible disconnect device must be fitted outside the equipment. For plug-in equipment, the socket must be fitted close to the equipment and easily accessible. • Never install the system near liquids or in an excessively humid environment. • Never allow a foreign object to enter the interior of the system. • Never block the system's ventilation grilles. • Never expose the system to direct sunlight or a heat source. • If the system must be stored before installation, storage must be in a dry place. The allowable storage temperature range is -25°C to +55°C without batteries, 0°C to +40°C with batteries, we recommend storage below 25°C) • This UPS can be used in a TN/IT/TT power system.
