4. ELECTRICAL CONNECTION

The electrical connection is part of the work which is normally provided by the
company that carries out the product installation. For this reason, the UPS
manufacturer shall not be held responsible for any damages due to wrong
connections.
USE QUALIFIED PERSONNEL ONLY
All the operations related to the electric connection must be carried out by
qualified and trained personnel.
WORK IN COMPLIANCE WITH THE LOCAL STANDARDS
The installation of Fluxpower HE must be carried out in compliance with
national and local regulations.
CONNECTION OF GROUND CABLE
The grounding of the UPS via the relevant terminal is mandatory. It is strongly
recommended to connect the ground terminal as first terminal.
The electrical connection is part of the work which is normally provided by the
company that carries out the electrical installation and not by the UPS
manufacturer. For this reason, the following recommendations are only an
indication, as the UPS manufacturer is not responsible for the electrical
installation. In any case we recommend to carry out the installation and the
electrical input and output connections in compliance with the local standards.
Cables must be selected bearing in mind technical, financial and safety
aspects. The selection and the sizing of cables from a technical viewpoint
depend on the voltage, on the current absorbed by the UPS, on the bypass
line and on the batteries, on the ambient temperature and on the voltage drop.
Finally, the kind of cable laying must be taken into particular consideration.
For more explanations regarding the selection and the sizing of cables, please
refer to the relevant IEC standards, in particular to IEC 64-8 standard.
"Short-circuit currents" (very high currents with a short duration) and "overload
currents" (relatively high currents with a long duration) are among the main
causes of cable damage. The protection systems normally used to protect the
cables are: thermal magnetic circuit breakers or fuses. Protection circuit
