2. Installation procedure
This chapter is dedicated to the installation method, how to mount and wiring the UPS.
2.1 Introduction
This chapter describes the basic requirements for the positioning and wiring of the power
supply. This description is a step-by-step installation guide, which provides a number of
guidelines for how to guide your service during assembly.
Warning - Installation may only be carried out by an authorized service center
1. Do not connect electrical appliances to the power supply before conrming that the power supply is
properly connected and congured.
2. The UPS should be installed by qualied technicians in accordance with the guidelines in this chapter.
Do not perform any electrical work that interferes with the electrical installation before and after the
UPS while the UPS is operating. Damage arising from this title (eg phase sequence replacement) is not
covered by the warranty.
Warning: dangerous batteries
Special precautions must be observed when working with batteries connected to the power supply.
After connecting the battery, the voltage at the terminals exceeds 400 Vdc and is potentially fatal.
It is recommended to use protective eyewear to protect your eyes from accidental electric arc. In
addition, it is recommended that:
- Remove rings, watches and all metal objects.
- Only use tools with insulated handles.
- If the battery leaks or the battery is otherwise damaged, replace it. Damaged batteries should be
stored in a container resistant to sulfuric acid and disposed of in accordance with local regulations.
If the electrolyte comes in contact with the skin, the contaminated area should be washed immedia-
tely with water.
2.2 Preliminary review
Please perform the following checks before installation:
- Verify that the supplied equipment, ie UPS and batteries, is not damaged by shipping. Any
damage should be reported immediately to the supplier.
- Verify the compliance of the supplied equipment with the installation requirements. The
power of the power supply is described on the label each time.

2.3 Location
The UPS is designed for indoor installation. The device should be in a clean, ventilated environ-
ment in order to maintain the ambient temperature within the required specications. The UPS
provides forced convection cooling through internal fans. Cold air enters the unit through the
ventilation openings located in the front of the enclosure and is blown out by the grills in the
rear of the enclosure. Do not block the ventilation openings.
Depending on the conditions of the room, the ventilation openings of the power supply
should be regularly cleaned, eg with a vacuum cleaner. Ventilation will ensure ecient cooling
and longer service life.
Note: The UPS should be installed on a stable and non-ammable surface.
2.3.1 UPS Room
The battery temperature should be stable as it is the main parameter that aects battery life
and capacity. The optimal operating temperature of the battery is 15-25 ° C. It is recommended
to maintain a nominal temperature of 20 ° C.
Working at higher temperatures shortens the battery life and reduces the battery capacity in
the lower battery. Each increase in battery operating temperature by another 8 ° C, reduces the
service life by 50%.
Keep batteries away from heat sources and hot air outlets.
When installing the battery outside the UPS, use the battery circuit as close as possible to the
battery. The connecting cables for the batteries and UPS should be as short as possible.
2.3.2 Battery room
If the device is not installed and needs to be stored, protect it from excessive humidity and high
temperatures. Keep batteries in a dry and cool place. The most suitable storage temperature for
batteries is 20-25 ° C. If the unit is not installed immediately, store it indoors to protect it from
excessive humidity and heat sources.
2.3.3 Storage
Before unpacking, carefully inspect the package provided or damage during transportation.
After removing from the package, check that the equipment does not show signs of damage. If
there are any damages, please notify the supplier immediately.
2.4. Unpacking, checking and setting up

2.4.3. Service space
On the side walls of the power supply unit there are no ventilation openings, therefore no space
is required on the side for ventilation purposes. For access to the device on each side, it is recom-
mended to keep min. 50 cm service area.
It is necessary to provide adequate space from the front of the power supply for easy operation
and the ability to draw cold air from the environment. Recommended 80 cm front space.
Due to the required access to the back of the power supply and free airow and circulation, the
recommended back space of the power supply is 50 cm.
2.5. Security systems
For safety reasons, it is necessary to install appropriate protections in the form of surge suppres-
sors or other protective devices in the UPS distribution board. This chapter provides general
practical information for installation by qualied electricians. In addition, sta with the appropria-
te knowledge and authority should be aware of the standards and standards applicable to the
local market for type and cross-section of wires, their arrangement and their load capacity. It is
recommended to use exible hoses type LgY or OpD.
2.5.1. UPS input power
The UPS should be powered from an electrical switchgear equipped with a suitable security
apparatus selected for maximum system power and exible hoses with appropriate current
carrying capacity selected for the protection used.
If you need to install RCDs on the UPS power supply, keep in mind that these units should:
Be sensitive to unidirectional DC current pulses (Class A)
Not be sensitive to transient current impulses
