UPS EVO DSP TT
Access is through the use of a tool or lock and key, or other means of security and is controlled
by the authorized person responsible for the location.
Recommended operating temperature, humidity and altitude values are listed on the “Technical
Specifications” section. Air conditioning may be required to provide these values.
Other requisites are:
The equipment and the batteries shall not be exposed to direct sunlight or placed near to a
heat source.
Do not expose UPS to rain or any liquids in general. Do not introduce any solid objects.
Avoid dusty environments or areas where dust of conductive or corrosive materials is present.
Air outlets of the UPS are on sides, front and back. Leave at least 75 cm at the front and both
sides and 50 cm at the back for maintenance and ventilation.
2.4.2 Electrical Requisites
The installation must comply with local national installation regulations.
The electrical distribution panels for the mains and separate Bypass mains inputs must have a
protection and disconnection system. Disconnection devices used in these panels shall disconnect all
line conductors and the neutral conductor simultaneously. The following table shows the recommended
size of the mains and separate Bypass mains input protection devices (thermal, magnetic and
differential) and the cable cross-sections for the linear loads.

Input magnetic protection devices shall have D characteristic.
*Load leakage currents are added to those generated by the UPS. If loads with high leakage currents
are present, adjust this value accordingly. It is recommended to adjust the protective device after
measuring the total leakage current with the UPS installed and operational with the intended load.
During transitory phases (power failure, return and voltage fluctuations) short leakage current peaks
may occur. Make sure that the protection is not activated in such cases.
If the loads have a nonlinear characteristic, the current on the mains input, separate
Bypass mains input may have a value that is 1.5-2 times the current phase value during
operation. In this case, size the neutral cables and the input/output protection
accordingly.
