and batteries. Please read all instructions before installing the equipment and save this manual for future reference.
• Not obeying the instructions written on this manual which may result with possible injury of the operator or damage
of the equipment.
• The equipment shall be packed and fixed properly during transportation to avoid fall down and proper equipment
should be used for transportation. Never transport in horizontal position.
• The UPS must always stands in a vertical position. Make sure that the floor can support the weight of the system.
• Connect the PE ground connector before connecting any other cable.
• UPS is designed for indoor use. To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity
controlled indoor environment, free of conductive contaminants. Ambient temperature must not exceed 40°C (104°F).
Do not operate near water or excessive humidity (95% maximum without condensation).
• UPS requires 3Ph-N+PE input connection.
• Do not connect the output neutral to the protective ground or protective bonding (except the TNC Option). Keor T
does not modify the neutral arrangements of the system; the use of an isolation transformer is required should it be
necessary to modify the neutral arrangements downstream Keor T.
• KEOR T must be protected from voltage surge with devices that are suited to the installation; the mains voltage surge
must be limited to 2kV. These protective devices must be sized to take into account all the installation parameters
(geographical position whether or not there is a lightning rod, whether or not there are other suppressors in the
electrical installation, etc )
• Even when connections removed, residual voltages of capacitors and/or high temperature may exist on connection
terminals and inside the UPS. Before working on terminals, check between all the terminals included PE that no
hazardous voltages exist.
• The connections shall be made with cables of appropriate cross-section in order to prevent the risk of fire. All cables
shall be of insulated type and shall not be laid out on the walking path of the persons.
• According to IEC 62040-2; this is a product for commercial and industrial application. In the second environment
