2. INSTALLATION

2.1 ENVIRONMENTAL REQUIREMENTS FOR INSTALLATION

Consult the following check list when installing the UPS:
• NETYS RT units are designed for use in enclosed environments.
• Position the UPS on a flat and stable surface in a properly ventilated room, well away from heat sources and avoiding direct exposure to sunlight.
• Ambient temperature should be maintained between 0 °C and 40 °C, and relative humidity below 90% (without condensation);
the optimum temperature in terms of maximizing battery life is 15-20 °C.
• Check that the UPS will not be installed in a dust-laden environment.
• Be certain that a clearance of at least 20 cm is left on all sides of the unit to ensure adequate ventilation and provide access to the rear panel.
• Take care not to stand the UPS or any other heavy object on cables.
• Check that the operating voltage and frequency settings are correct for the mains power supply at the installation site. Details for
the UPS will be found on the data plate affixed to the rear panel.
• When making the RS232 serial connection, use only the cables and accessories supplied or specified by the manufacturer.
• When the UPS is first used, it is advisable to leave the battery on charge for a minimum of 8 hours.
PRECAUTIONS IN THE EVENT OF DAMAGE
DO NOT OVERTURN THE BATTERIES.
Packing materials that have been broken, punctured or torn in such a way as to reveal the contents must be kept
separate in a secure area, and inspected by skilled staff. Any packing considered unsuitable for shipment of the
contents must be set aside immediately and kept secure, and the sender or recipient contacted.

2.2 ELECTRICAL REQUIREMENTS

The installation and the system must comply with pertinent national statutory regulations.
The fixed power distribution unit must include protection and isolation for the utility supply and the back-up supply. In the event that
a residual current device is installed on the UPS input line (optional), this must be located upstream of the power distribution unit.
The following table indicates the sizing of input protection devices that will ensure correct installation.
WARNING!
Use type B two-pole selective (S) RCDs Any leakage currents at the loads will be added to that of the UPS, so
that current peaks can occur during transients (loss and restoration of mains supply), although these will be of
very short duration. Where loads generate high leakage current, make certain the rating of the RCD is suitably
matched. In any event, always conduct a preliminary test for current leakage to earth. When connecting the UPS
to the mains and the load, it is highly recommended that protective devices are installed. The protective devices
must use approved components that meet safety standards.
