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 (Low Power Consumption) fan is an energy efficient fan
unit consisting of a PM (Permanent Magnet) motor with matching
motor control and optimized fan blade design for LPC 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
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.

The fan comes with a 2-meter cable for the wiring between motor and motor
controller.
445927 DA 600 LPC cable set 5m can be ordered, if 2m is insufficient.
The power supply to the motor controller does not require a shielded cable.
It comes with motor controller, fan blades and fan suspension.
3-blade, 230 V adjustable fan.
To be applied if you require a low energy consumption, both at partial and
full load.
ErP 2015 approved.
DA 600 LPC 11-3 should not be used for negative pressure higher than 90
Pa.
DA 600 LPC 13-3 should not be used for negative pressure higher than 120
Pa.
445173 DA 600 LPC 11-3 fan 230V1 50/60Hz TH
The fan is the same as part no. 445170, but includes a thermal cutout.
445175 DA 600 LPC 13-3 fan 230V1 50/60Hz TH
The fan is the same as part no. 445172, but includes a thermal cutout.
The thermal circuit breaker ensures that the motor disconnects if it gets too
hot. For safety reasons, the fan must be connected manually before it can
be activated again.
Fans with thermal circuit breakers are normally only used in places where
this is a legal requirement, e.g. in Sweden.

445185 DA 600-7F-3 VFD fan 230V1 50/60Hz
This product consists of the fan 445090 + a DOL 38-3 frequency converter.
The frequency controller reduces the energy consumption of the individual
fan at partial load compared with a similar triac-controlled fan.
High pressure stability, high performance, and relatively high energy con-
sumption.
The fan is often used where high working pressure is required, for instance
in connection with under-floor exhaustion, air cleaning etc.
The frequency converter included is controlled via a 10-0 V signal.
A pre-mounted, shielded cable used between the motor and the frequency
converter, is included. The distance between the frequency converter and
the motor must not exceed 5m. The supply to the frequency converter is not
dependent on a shielded cable.
ErP 2015 approved.

3.2 Positioning of fan in the exhaust unit
The connection box on the fan must face downwards when the fan is used as a wall exhaustion.
Mount the four fan suspensions using 6 x 25 screws in
the marked positions. Be careful not to over-tighten the
screws.
DA- fans must face the fan blades downward.
Position the legs of the fan in the four fan suspension
units.
Fasten all four fan supports using cable ties around the
fan suspension and rubber suspension.
3.3 Safety distance
If the distance from the floor to the fan blade is less than
270cm, mounting a protective mesh in the inlet bell
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 or covered 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 [}11].

200 mm
200 mm

In order to ensure access of cables and cooling of the
motor controller/frequency, the distances to the sur-
roundings must be met.
Distance to top and bottom = 200 mm
Distance to both sides = 10 mm
3.6 Position of motor controller/frequency converter
The motor controller/frequency converter is positioned
so that the ambient temperature is between ÷ 20°C and
+ 40°C and protected against direct sunlight.
Temperature, operating ÷ 20 °C to + 40.
Start temperature ÷ 15 °C to + 40.
Mount the motor controller/frequency converter as close
to the fan as possible.
The 2 m cable included must not be extended.
However, a motor cable of 5 m can be ordered if the 2 m
is not sufficient.
The controller/frequency converter can be mounted on a
wooden plate fastened to a rafter on the ceiling or di-
rectly on the chimney.

4 Installation guide
4.1 Electrical connection
Wait 10 minutes for the capacitors to discharge to a safe voltage level before servicing and trou-
bleshooting.
Failure to observe this precaution could result in serious injury or loss of life.
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 Overvoltage protection
SKOV A/S equipment are protected for high level of surge transient, but in some cases, specially in areas with
frequent lightning strikes and power outage, additional protection is necessary. To reduce the risk of damaging
the electronic equipment by large surge overvoltage, it is therefore recommended, always to install Surge Pro-
tection Devices (SPD) in the mains supply.
As a minimum a Type 2/Class II device should be installed in each livestock house wiring box. A device of
8/20us - 40kA/phase or higher is recommended.
In areas with a high amount of surge overvoltage a Type 1/Class I device is reccomended to be installed at the
transformer/ATS as the first protection device, together with Type 2 in each livestock house wiring box as sec-
ond protection device. A Type 1 device of 10/350us - 25kA/phase or higher is are recommended.
Local electrical engineers must be consulted for correct dimensioning and installation of the SPD device.

4.1.4 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.
4.1.5 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.
