DA 820F-3 VFD 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.

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.
DA 820F-3 VFD 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...

When washing the inside of the ducts, fan blades must stand still. Remember that fans do not stand high-pressure cleaning. If the inside of the duct needs to be cleaned extra thoroughly SKOV A/S recommends washing from above. When washing the fan, the fan must run around.
DA 820F-3 VFD 6 Trouble shooting instructions Remember to shut the fan off at the power supply isolator prior to troubleshooting. 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.
