General warnings
The operations described in the manual may be performed only by qualified personnel.
The status of qualified personnel referred to in this manual will be, as a minimum, that which meets
all the standards, regulations and laws regarding safety applicable to the tasks of installing and oper-
ating this unit.
The responsibility for designating qualified personnel will always fall to the company to which the
personnel belong. It is necessary to decide which workers are suitable or not for carrying out specific
work to preserve their safety at the same time as complying with occupational safety legislation.
These companies are responsible for providing appropriate training in electrical equipment to their
personnel and for familiarising them with the contents of this manual.
All applicable safety-related legislation for electrical work must be complied with. Danger of electric
shock.
Compliance with the safety instructions set out in this manual or in the suggested legislation does
not imply exemption from other specific standards for the installation, place, country or other circum-
stances that affect the inverter.
Opening the door of the housing does not imply there is no voltage inside.
The risk of electric shock exists even after disconnecting from the grid, the wind generator and the
auxiliary supplies.
Only qualified personnel may open it, following the instructions in this manual.
In units which include an isolating switch, never switch from OFF to ON without first ensuring there
is no DC voltage entering the equipment.
As long as the wind generator receives wind, the DC cables will be live.
The entire manual must be read and understood in full prior to manipulating, installing or operating
the unit.
AAY2000IKI04 iii
Installation manual Ingeteam Power Technology, S.A.

Following is a list of the basic obligatory safety standards for each country:
• RD 614/2001 and RD 1699/2011 in Spain.
• CEI 11-27 in Italy.
• DIN VDE 0105-100 and DIN VDE 1000-10 in Germany.
• UTE C15-400 in France.
Carry out all control and handling without voltage.
As a minimum security measure in this operation, the so-called five golden rules should always be
followed:
1. Disconnect
2. Prevent any possible resupply
3. Check there is no voltage
4. Ground and short circuit the equipment
5. Protect from live elements, if any, and put up safety signs around the work zone.
Until these five steps are completed, the work area cannot be considered voltage-free and any work
performed will be considered to be work on live equipment.
Category III - 1000-Volt measuring instruments must be used for checking for the absence of voltage.
Ingeteam accepts no liability for any damages caused by improper use of the equipment.

Potential hazards for people
Bear in mind the following warnings concerning personal safety.
DANGER: Electric shock.
The equipment may remain charged after disconnecting the wind generator and mains power.
Carefully follow the mandatory steps in the manual for removing the voltage.
DANGER: Explosion.
There is a very low risk of explosion in very specific cases of malfunction.
The casing will protect people and property from the explosion only if it is correctly closed.
DANGER: Crushing and joint injuries.
Always follow the indications in the manual on moving and placing the unit.
The weight of this unit can cause lesions, serious injury and even death if not handled correctly.
DANGER: High temperature.
The flow of air from the side and top outlets can reach high temperatures which can cause injury to
people exposed.
The back and side of the unit act as a radiator. Do not touch, danger of severe burns.
AAY2000IKI04 v
Installation manual Ingeteam Power Technology, S.A.

Potential hazards for the equipment
Bear in mind the following warnings concerning protection of the equipment.
Should the grid or the invertor fail, on power will be extracted from the wind turbine, and so the wind
generator must have a braking system or additional speed limiting to guarantee it never exceeds the
equipment’s maximum operating limits (Vdcmax= 550 V).
CAUTION: Ventilation.
The unit requires quality air flow while it is operating.
Keeping the unit in the upright position and the inlets free of obstacles is essential for this air flow
to reach the inside.
CAUTION: Connections.
After all duly authorised handling, check that the inverter is ready to start operation. Only after this
can it be connected following the instructions in the manual.
Do not touch boards or electronic components. The most sensitive components can be damaged or
destroyed by static electricity.
Do not disconnect or connect any terminal while the unit is operating. Disconnect and check for
absence of voltage first.
Personal protection equipment (PPE)
Use all items comprising the protection equipment.
Chapter “4. Safety instructions” contains references to the use of this equipment depending on the situation.
The standard personal protective equipment is:
• Safety goggles for mechanical hazards
• Safety goggles for electrical hazards
• Safety footwear
• Helmet

1. Overview
1.1. Introduction
The purpose of this manual is to describe the Ingecon® μWind unit and to give appropriate information for its correct
receipt, installation, start-up, operation and maintenance.
1.2. Equipment description
An inverter is a circuit used to convert direct current to alternating current. The function of the Ingecon® μWind units
is to convert the direct current generated by wind generators to alternating current and so enable it to be fed to the
electricity grid.
1.2.1. Models
The main models in the Ingecon® μWind range are:
Ingecon® μWind 2.5 TL Ingecon® μWind 2.5
Ingecon® μWind 3 TL Ingecon® μWind 3.3
Ingecon® μWind 3.3 TL Ingecon® μWind 5
Ingecon® μWind 3.68 TL
Ingecon® μWind 3.8 TL
Ingecon® μWind 4.6 TL
Ingecon® μWind 5 TL
Ingecon® μWind 6 TL
1.2.2. Options
All these models in the Ingecon® μWind range may incorporate the following options:
• DC circuit breaker
• MC3-type quick connectors
• Ingecon® μWind Interface (IWI) connection kit AAY0089
1.2.3. System description
There are several configurations available depending on the features of the equipment being used. These possibilities
are discussed below.
A microgeneration wind power system must have a braking and stopping system in order to ensure the
safety of people and the equipment.
If the braking and stopping system is supplied by others, Ingeteam accepts no responsibility for any
malfunction or the consequences thereof.
