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

The ON/OFF fan is controlled with a sturdy frequency converter for

three-phase fans.

The frequency converter is controlled by a 10-0 V signal from a cli-

mate controller.

The fans are designed for mounting in exhaust units and wall exhaustion in livestock houses where the ventila-

tion system operates in the high pressure range.

The fans bear a CE marking and have a sturdy four-point suspension.

2 Product survey

2.1 DA 820F VFD high pressure

445040 DA 820F VFD fan high pressure 400V3 50/60Hz

This product consists of a 3x400 V fan and a frequency converter.

The frequency converter is controlled via a 10-0 V signal.

The max. current consumption of the fan is 4.1 A.

The fan is supplied with a 5 m shielded cable to be used between the motor

and the frequency converter. The distance between the frequency converter

and the motor must not exceed 5 m. The supply to the frequency converter

does not require a shielded cable.

High pressure stability, high performance, and relatively high energy con-

sumption.

Is used where a high working pressure is required, up to 180 Pa. High

power consumption and noise level must be anticipated at maximum out-

put.

The fan may only be used in Dynamic MultiStep systems and must not be

combined with other fans. Standard MultiStep is not an option due to the

large pressure differences.

ErP 2015 approved.

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.
