3.3. Important Notice for UPS
• The equipment may only be installed and commissioned by authorized LEGRAND UPS Technical Service
Personnel.
• This manual contains important instructions that you should follow during installation and maintenance of
the UPS 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.
