Definition of “operator” and “specialized technician”
The professional figure responsible for accessing the equipment for ordinary maintenance purposes is defined with
the term operator.
This definition covers personnel that know the operating and maintenance procedures for the equipment, and that
have been:
1. trained to operate in accordance with the safety standards relating to the dangers that may arise where
electrical voltage is present;
2. trained to use Personal Protective Equipment and to carry out basic first aid.
The professional figure responsible for the installation and start-up of the equipment, and for any extraordinary
maintenance, is defined with the term specialized technician.

GENERAL PRECAUTIONS
This manual contains detailed instructions for the use, installation and start-up of the Sentry MPS-HP.
Read the manual carefully before installation. For information on using the SENTRY MPS-HP, the
manual should be kept close at hand and consulted before carrying out any operation on the device.
This device has been designed and manufactured in accordance with the standards for the product, for normal
use and for all uses that may reasonably be expected. It may under no circumstances be used for any purposes
other than those envisaged, or in any other ways than those described in this manual. Any interventions should
be carried out in accordance with the criteria and the time-frames described in this manual.
•The first connection to be made is the connection between the earth conductor and the terminal
with the symbol shown here:
•The SENTRY MPS-HP must not operate without an earth connection.
•The device must be installed and used in compliance with the instructions set out in this text and with the
procedures suggested.
•The operating and maintenance personnel and specialized technicians should be adequately trained in the
safe use and maintenance of the device. They should always operate with due precaution and wear
personal protective equipment (PPE).
•Maintenance must not be carried it inside the SENTRY MPS-HP when it is being powered from the mains
or when the UPS is operating via the battery. For maintenance close the maintenance disconnector SWMB
and open all the other switches. The disconnecting switch or battery fuse located in the battery cabinet
should also be opened. Before carrying out any operation, always measure the voltage with a multimeter
to ensure that there are no dangerous voltages.
•There are dangerous voltages inside the equipment even when the input and battery switches are in the
open position; personnel must wait around ten minutes for the capacitors to discharge before working on
the inside of the SENTRY MPS-HP.
•The specialized technician must comply scrupulously with the following instructions for the installation
and maintenance of the SENTRY MPS-HP:
-use insulated tools.
-observe polarities.
-if the fuses need replacing, replace only with the same type.
-the replaced components must be disposed of in accordance with the legislation in force in the
country of installation.
•Do not deactivate the protection devices or ignore the warnings, precautions and alarms described in this
manual or those shown on data plates on the equipment.
•Promptly replace any danger signals if they should become illegible through usage.
•The UPS must be used only with all side and internal panels duly secured and with the front door closed.
•Under no circumstances may the structure of the equipment, the devices mounted on it, the operating
sequence, etc. be modified, tampered with or altered in any way without first consulting the manufacturers.
•All ordinary and extraordinary maintenance operations must be noted in the appropriate register with the
date, time, type of intervention, operator name and any other useful information.
•Once the maintenance operations have been concluded, a thorough check should be made in order to
ensure that no tools and/or other materials have been left inside the cabinet.

page 6 / 75 0MNA080A55-GB REV 01
•In the event of faults or malfunctions, contact your local distributor or Aros. All repair operations must be
carried out by authorized technicians.
•Under no circumstances must water be used to clean the internal or external electrical parts of the cabinet.
•Do not leave the device exposed to rain or to the elements. The device must be stored and used in premises
that comply with the environmental requirements set out in this user manual.

1. Preliminary operations
1.1 Removing the packaging and positioning the device
On delivery, the packaging must be inspected to ensure that it is whole and that it has not been crushed or dented.
Check in particular that neither of the two impact resistant devices on the packaging is red; if one of them is red,
follow the instructions on the packaging.
The essential details of the device are provided on the shipping document. The marking, weight and dimensions of
the various items making up the packing list are shown.
Check the state of the device by means of a visual inspection of both the inside and the outside. Any dents seen
mean that it has suffered knocks during shipping, which could compromise the normal operation of the device.
1.2 Storage
In the following situations:
- installation not immediately after delivery;
- de-installation and storage while awaiting relocation,
place the device in covered premises that are protected from direct contact with atmospheric agents and dust. The
following environmental values are those allowed in the storage area:
Temperature: -25 ÷ + 75 °C
Relative humidity: 30÷95 % max.

page 10 / 75 0MNA080A55-GB REV 01
For the installation of a battery cabinet, if provided with the uninterruptible power supply, follow the
instructions given in the specific manual.
The list of material provided may vary depending on the order specifications. As a general rule, the packaging
should include the following: this manual, the installation drawing, the warranty and eventual accessories.
1.3 Handling
The equipment must only be handled by adequately trained personnel. It can be unloaded from the vehicle and put
into place by lifting the box or the wooden deck to which the equipment is secured with a fork-lift truck. A
transpallet or fork-lift truck should be used for the permanent positioning of the equipment, in accordance with the
instructions provided below.
1Insert the forks of the fork-lift truck in the lower part of the device, from the front or back, and ensure
that they stick out about 30 cm on the other side.
If a transpallet is used, raise the device only as much as is strictly necessary.
2Secure the device to the transpallet or fork-lift before moving it.
Risk of overturning
In order to avoid the risk of the device overturning, ensure that it is firmly secured to the transpallet or
fork-lift truck by means of appropriate ropes before moving it.
When being moved the cabinet should be handled with care; knocks or drops can damage it. Once in position,
remove the packaging carefully in order not to scratch the device.
The packaging should be removed as follows:
1. Cut the bands
2. Carefully remove the cardboard packaging.
3. Remove the screws securing the cabinet to the wooden base.
4. If using a transpallet, remove the device from the pallet and set it on the floor, using the same
precautions as set out in the section on Handling.
