User’s manual 2UPS EVO DSP PLUS Modular
1Introduction
UPS EVO DSP PLUS Modular (UPS means Uninterruptible Power Supply) is the result of constant technological
research aimed at obtaining the best performance at the lowest cost.
UPS EVO DSP PLUS Modular is an advanced ON-LINE UPS built specifically to protect your computer from any
irregularities in the AC line (for example blackouts, brownouts, over voltages, micro-interruptions), which often
cause damage to hardware and software.
All that is possible because UPS EVO DSP PLUS Modular is a Double-Conversion ON-LINE UPS.
Under normal AC line condition UPS EVO DSP PLUS Modular provides an automatic Output Voltage regulation from
the Rectifier and Inverter blocks and filters out frequently occurring electrical disturbances (high Voltage
transients, spikes, interferences, etc.), thus protecting the devices connected to its outlets. During a power
failure, UPS EVO DSP PLUS Modular continues supplying adequate AC power (with a true sine wave) to all
connected devices through batteries and by its DC/AC converter (Inverter).
UPS EVO DSP PLUS Modular protects the devices from accidental overload or Inverter fault by an Automatic Bypass
that directly connects the AC Input line with Output LIne.

3Receipt and site selection
3.1 Site Selection
We recommend paying attention to the below points in order to choose a correct placement for your UPS:
•The UPS is designed to operate in a protected environment (e.g. offices). We therefore recommend
installing it in a place with very little or no humidity, dust or smoke.
•When the UPS is brought from a cold place to a warmer place, humidity in the air may cause condensation
in the UPS. In this case, allow UPS to stand for two hours in the warmer place before beginning with the
installation.
•In all circumstances, see chapter 12 “Technical Characteristics”for environmental specifications and
check that the selected area meets these criteria.
•During normal operation the UPS discharges a minimal amount of heat. So it is necessary to leave at least
30 cm of unobstructed space all around the UPS in order to keep it properly ventilated.
•Do not obstruct ventilation holes.
•Do not insert objects or pour liquids in the ventilation holes.
•Do not rest any object on top of the UPS.
•Do not keep liquids, flammable gases or corrosive substances near the unit.
•Install the UPS on a properly tiled floor. Avoid the installation on a floor that is not tiled flat.

3.3 Moving the Cabinet
The UPS is fixed on the pallet with 4 fixing cabinet plates. When removing it, pay
attention to the movement of the casters to avoid accidents.
The cabinet can be pushed forward or backward only. Pushing it sideward is not
allowed. When pushing the cabinet, pay attention not to overturn it as the gravity
center is high.
1. If you need to move the UPS over a long distance, please use appropriate equipment like a forklift. Do not
use the UPS casters to move over a long distance.
2. After the UPS has been removed from the pallet to ground, we suggest that at least three people move the
UPS to the installation area. One person holds a lateral side of the UPS with hands, another holds the other
lateral side of the UPS with hands, and the other person pushes the UPS either from the front side or from
the back side to the installation area and avoid tipping the UPS.
3. The casters are designed to move on level ground. Do not move the UPS on an uneven surface. This might
cause damage to the casters. Toppling the UPS could also damage the unit.
4. Ensure that the weight of UPS is within the designated bearing capacity of any handling equipment.
5. At the bottom of the UPS, the four casters help you to move the UPS to a designated area. Before you move
the UPS, please turn the four leveling feet counter clockwise to raise them off the ground. This protects the
leveling feet from damage when moving the UPS. Refer to Figure 3.6.
