Product and Documentation Changes
SKOV A/S reserves the right to change this manual and the product described herein without further notice. In
case of doubt, please contact SKOV A/S.
The date of change appears on the front and back pages.
IMPORTANT: NOTE CONCERNING ALARM SYSTEMS
When regulating and controlling the climate in livestock buildings, breakdowns, malfunctions or faulty settings
may cause substantial damage and financial losses. It is therefore essential to install a separate, independent
alarm system that monitors the house climate concurrently with the climate and production computer.
According to EU-directive No. 98/58/EU an alarm system must be installed in all mechanically ventilated
houses.
Please note that the product liability clause of general terms and conditions of sale and delivery specifies that an
alarm system must be installed.
In case of an operating error or improper use, ventilation systems can result in production losses or
cause loss of lives among animals.
SKOV A/S recommends that ventilation systems be mounted, operated and serviced only by
trained staff and that a separate emergency opening unit and an alarm system be installed as well as
maintained and tested at regular intervals, according to SKOV A/S’ terms and conditions of sale
and delivery.

3 Mounting Guide
3.1 Positioning of Fan in the DA 600 Exhaust Unit
The wires to the fan must be short-circuited to avoid the fan rotating (driven by the air) as this
can lead to voltage in the wires.
The fan weighs around 13 and 16 kg.
Mount the four included fan suspension units in the exhaust unit
duct.
Position the legs of the fan in the four fan suspension units.
The fan is positioned in the fan suspension units of the exhaust
unit duct secured only by its own weight and it must therefore
be fastened in all four legs using split pins, strips or similar.
Important!
Check that the fan is correctly positioned in relation to the
direction of the air.
For air outlets, the fan blade must be at the bottom and the
motor at the top.
For air inlets, the motor must be at the bottom and the fan blade
at the top.
3.2 Safety Distance
If the distance from the floor to the fan blade is less than 270
cm, a safety net must be mounted in the bell mouth.
270 cm

DA 800 LPC
3.3 Mounting the Motor Control
Incorrect mechanical mounting can result in overheating and reduced performance.
3.3.1 Position of Motor Controller
Motor controller 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 control must be positioned as shown in
3.3.1.
3.3.2 Ensure access and cooling of Motor Controller
In order to ensure access and cooling of the motor
controller, the distances to the surroundings of 150 mm
must be adhered to.

10 Technical User Guide
DA 800 LPC
3.3.3 Positioning of Motor Controller.
The motor controller is positioned so that the ambient
temperature is between - 40°C and + 50°C.
Mount the motor controller as close to the fan as possible.
The 2 m cable included must not be extended.
Mount the controller on a wooden plate fastened to a rafter on
the ceiling or directly on the chimney.
Install the controller under the eaves protected from driving rain
and in shade protected from direct solar radiation.

4 Installation Guide
4.1 Electrical Connection
Qualified personnel must perform installation, service and fault-finding of all electrical
equipment in accordance 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. SKOV A/S does not supply the power
supply isolator.
4.1.1 Cabling in the Exhaust Unit
Drill a hole in the exhaust unit duct for the fan cable and pull it
along a leg to the same side as the motor controller.
4.1.2 Cabling into the Motor Controller
In order to prevent water from running into the motor
controller 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.
