3.3 POSITIONING AND INSTALLATION
The UPS must be installed in a clean and dry room, preferably not dusty. The User
must ensure that there is enough air exchange in the room so that the equipment can
be adequately cooled; if this is not guaranteed, the room must be adequately aired.
3.4 ELECTRICAL CONNECTION
The electrical connection is part of the work which is normally provided by the
supplier 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 connections
of the input and output in compliance with the local standards.
During the electrical installation take particular care to check the phase rotation with
a suitable instrument.
The terminal boards are positioned at the front of the UPS, under the breakers. To
access the terminals remove the protection, extracting the fixing bolts.
WARNING
The connection to the mains must be carried out with protection fuses between the
mains and the UPS.
The use of residual current devices in the line supplying the UPS is
unadvisable. The leakage current due to the RFI filters is rather high and it can
cause spurious tripping of the protection device.
According to the EN62040-1 standard, in order to take into account the UPS’ leakage
current, residual current devices having adjustable threshold can be used.
3.5 BATTERY INSTALLATION
IMPORTANT
For battery installation please respect the prescriptions of the EN62040-1 standard.
To obtain the battery life indicated by the battery manufacturer, the operating
temperature must remain between 0 and 25 °C. However, although the battery can
operate up to 40 °C, there will be a significant reduction of the battery life.
To avoid the formation of any kind of potentially explosive hydrogen and oxygen
mixture, suitable ventilation must be provided where the battery are installed (see
EN62040-1).
It is recommended to install the batteries when the UPS is capable of charging them.
Please remember that, if the battery is not charged for periods over 2-3 months they
can be subject to irreparable damage.
