2 Introduction
The product described in this manual is an Uninterruptible Power Supply (UPS). It is a true
online, continuous duty, double conversion, solid state, three-phase system, providing con-
ditioned and uninterruptible AC power to protect the end-user's load.
Eaton E Series DX products are also capable of ECO mode. ECO mode means UPS load is
powered by bypass AC supply while in case of abnormal AC supply the load will be supplied
by accumulator battery after conversion through inverter. As the energy conversion effi-
ciency reaches as high as 98% and transfer time less than 10ms under ECO mode when
there is normal AC supply, the energy saving effect of UPS is remarkable.
Remark: ECO mode is applicable only to single unit.

4 Mechanical installation
The UPS and accessories are delivered on a specifically designed pallet that is easy to move
with a forklift or a pallet jack. Keep the UPS always in upright position and do not drop the
equipment. Do not stack the pallets.
Note!
A claim for shipping damage must be filed immediately and the carrier must be informed
within 7 days of receipt of the equipment. The packing materials should be stored for
further investigation.
Unpack the equipment by removing the packing and shipping materials. Make a visual inspection.
Remove the equipment from the pallet and make sure that the floor surface is solid and
suitable for the wheeling and heavy weight.
Remove cover plate → Remove side plate → Remove stuffing and fix
12
Check the information on the type designation label of the equipment to verify that the unit is
of the correct type. The type designation label includes ratings, a CE marking, a type code, a
part number and a serial number. The serial number is important when making inquiries. It
allows individual recognition of the equipment.
13
4.3 Planning before installation
The equipment must be installed in upright position. The equipment requires space to front
and back to enable cooling airflow. Service and maintenance require more than 40cm clear-
ance on right hand side. All cooling air enters at front and exits at unit rear. The required
minimum clearance from unit rear to an obstruction is 50cm. Because the service and user
access is in the front there should be reserved enough space (min 60cm).
14
4.4 Cabinet installation
The required distance for UPS units should allow for service access. The same applies to
the battery cabinet(s) that should be installed next to the UPS cabinet(s).
Caution!
UPS cabinet(s) can fall over if the installation brake pads are not used. Both rear and
front pads must be used to secure the UPS cabinet to the floor.
Use a 19mm wrench in clockwise direction to screw the brake pad down to the ground,
keeping the machine from moving.
Warning!
All operations inside the unit must be performed only by a service engineer from the
manufacturer or from an agent, authorised by the manufacturer.
The operation of the MBS is allowed for a service engineer from the manufacturer or from an
agent, authorised by the manufacturer. The full UPS wiring diagram with a MBS switch is
presented in the installation part of the manual.

1.If UPS rectifier input and bypass input are supplied from two mains:
Connect the mains 1 supply cables to the UPS rectifier input terminals L1, L2, L3, N and PE.
Connect the mains 2 supply cables to the UPS bypass input terminals L1, L2, L3, N and PE.
23
2.If UPS rectifier input and bypass input are supplied from one mains only:
Connect the mains supply cables to the UPS rectifier input terminals L1, L2, L3, N and PE .
The following three jumpers must be fixed between the rectifier and bypass input terminals:
L1-L1, L2- L 2, L3- L3.
Warning!
24
In order to gain access to the external electrical connections it is necessary to remove the
front terminal protective panel of the UPS. Before the cables are connected they shall be
passed through the cable glands to hold them in position and tightened.
Ensure that the UPS is isolated before removing front terminal protective panel.
Caution!
Notice!
Should there be any variation in the conditions it will be necessary to verify whether the
cable dimensions satisfy the requirements of IEC-287 and DIN VDE 0298. In cases
where the cables are so long that they cause a drop in voltage of >3%, a larger
dimension shall be selected.
25
Routing of communication cables or data lines should be kept separate from the UPS input,
output, and external battery cables.

Notice!
The following label must be displayed on all switching devices installed in the same
electrical system as the UPS, even when these are located at a distance from the area
in which it is located (according to European standard EN 62040-1-1).
Warning!
Warning!
In the event of malfunction, the battery cabinet chassis or battery cabinet frames may
become live!
Warning!
Special care should be taken when working with the battery cabinet associated with
the Eaton E Series DX 20 - 40 kVA. W hen the battery cabinet is connected the overall
voltage exceeds 400V. It is very important to ensure that the batteries are installed
separately, in a dedicated battery cabinet.
27
Notice!
The most common battery type used in UPS installations is the valve regulated battery.
Valve regulated cells are not sealed. The amount of gas given off is less than for
flooded cells, but when planning the battery installation, allowance must be made for
adequate ventilation and heat dissipation. Valve-regulated cells are not completely
maintenace- free. They must be kept clean and their connections checked periodically
to ensure they are tight, and that there is no evidence of corrosion. It is inevitable that
the batteries will lose charge during transportation and storage; before attempting to
carry out an autonomy test, ensure that the batteries are fully charged as this may take
several hours. Cell performance typically improves after a few discharge/recharge
cycles.
Notice!
The requirements of the EC directives are satisfied when battery cabinet are used with
original accessories. If alternative batteries are used, you must ensure that the appli-
cable EC directives are met and declare conformity.
Warning!
28
5.5 Connections between battery cabinet and UPS
Make sure the Protective Earthing (PE) connected first.
Warning!
Batteries are a potential source of danger due to their electrical charge and chemical
composition. Therefore observe the battery handling instructions of the manufacturer.
These usually can be found in the material which accompanies the shipment.
