IMPORTANT
Notes concerning alarm systems
Breakdowns, malfunctions or faulty settings may cause substantial damage and financial losses when regulat-
ing and controlling the climate in a livestock house. It is therefore essential to install a separate, independent
alarm system that monitors the house climate concurrently with the climate and production controller. According
to EU-directive No. 98/58/EU, an alarm system must be installed in all mechanically ventilated houses.
We would like to draw your attention to the fact that the product liability clause of general terms and conditions
of sale and delivery specifies that an alarm system must be installed.

1 Product description
An LPC fan is an energy efficient fan unit consisting of a PM motor
with matching motor control and opimised wing design for LPC
(Low Power Consumperion) and Dynamic MultiStep systems.
All variants of LPC fans are completed at the factory, so both the
motor and fan blade match the current application.
ON/OFF fans are constructed using a standard-dimensioned AC
motor, as well as an optimized blade design.
All ON/OFF fans are completed at the factory, so both the motor
and fan blade match the current application.
ECT/DCT fans are supplied with an integrated motor and fan
blades cast in aluminum. ECT/DCT fans are used as ON/OFF fans.
ECT fans can also be used as a Triac regulated fan.
The fans are designed for mounting in exhaust units and wall exhaustion in livestock houses where the ventila-
tion system operates in the low-pressure range, i.e. in LPV, diffuse livestock houses and Combi-Tunnel live-
stock houses.
The fans bear a CE marking and have a sturdy four-point suspension.

mouth may be required to meet the statutory require-
ments.
3.4 Position of motor controller/frequency converter
Motor controller/frequency converter must not be built-in,
covered or mounted directly on the chimney and must be
mounted on a solid, level surface.
In order to uphold protection classifications, access and
cooling, the motor controller/frequency converter must
be positioned as shown in section Mounting distances
for the motor controller/frequency converter [}14].
3.5 Mounting distances for the motor controller/frequency converter
In order to ensure access of cables and cooling of the
motor controller/frequency converter, the distances to
the surroundings must be met.

3.6 Position of motor controller/frequency converter
The motor controller/frequency converter is positioned
so that the ambient temperature is between ÷ 40 °C and
+ 50 °C.
Mount the motor controller/frequency converter as close
to the fan as possible.
Do not extend the supplied 2-meter cable.
However, for fan 1x230 V, a motor cable on 5 m can be
ordered if the 2 m is not sufficient.
The motor controller/frequency converter can be
mounted on a wooden plate fastened to a rafter on the
ceiling.

4 Installation guide
4.1 Electrical connection
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. The power supply isolator is not included.
4.1.1 Disclaimer at retrofitting fans
In the case of retrofitting fans in an existing house, regardless of ON/OFF fans, LPC fans or frequency convert-
ers SKOV recommends that a local expert is involved in checking the electrical installations. The focus should
be on cable dimensions, overload protections, local transformers, etc. It is of outmost importance to take the fan
specifications into account and, at the same time, ensure that local requirements are fulfilled.
4.1.2 Mains supply dimensioning regarding harmonic distortion
LPC motor controllers and frequency converters function like any other electronic power converter by converting
AC to DC. As this conversion produces a non-sinusoidal current, the mains supply for the controller is affected
by harmonic distortion.
The electrician or the user of the equipment must ensure, possibly through contact with the supply company,
that the equipment is connected to a properly sized mains supply.
4.1.3 Cabling in the exhaust unit
Drill a hole in the exhaust unit duct for the fan cable and
pull it along a support to the same side as the motor con-
troller/frequency converter.

Technical User Guide 17
4.1.4 Cabling into the motor controller/frequency converter
In order to prevent water from running into the motor
controller/frequency converter via cables and screwed
connections, the cabling must be carried out so that it
can stand water around the cable in the gasket of the
screwed connection.
