Residual current devices
Only universal (type B, B+) RCD protective devices are permitted.
Like frequency inverters, RCD protective devices cannot provide personal safety while operating the device, pulse
charge currents from the capacitors in the integrated EMC filter lead to the RCD protective device triggering without
delay.
We recommend residual current devices with a trigger threshold of 300mA and delay triggering. (super-resistant, char-
acteristic K)

Transportation and storage
All fans are packaged at the factory to withstand normal transport handling. When handling the goods use suitable lift-
ing equipment in order to avoid damage to fans and personnel. Avoid blows and shock loads. Store the fans in a dry
place protected from weather and dirt until final installation.
Warning
• The unit is heavy. Be careful during transport and installation. Risk of injury through pinching. Use
protective clothing.
• Do not lift the fans by the connecting cable, connection box, motor bracket, impeller or inlet cone.

Installation
Danger
• Make sure that the mains supply to the unit is disconnected before performing any maintenance or
electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Warning
• The units electrical connection to the mains supply must be preceded by an all pole circuit breaker with a
minimum 3 mm gap.
• Do not lift the fans by the connecting cable, connection box, motor bracket, impeller or inlet cone.
• Do not block or cover the drainage gap around the bottom of the fan.
The fan should be installed horizontally. Make sure the assembly of the fan is firmly fixed and stable. The fans must be
installed to ensure that service and maintenance can be performed easily and safely. Disturbing noise can be reduced
by installing silencers (available as an accessory). Electrical connections are made according to the wiring diagram in
the terminal box, markings on terminal blocks or on cable. All 3 phase fans are delivered from factory in 400 V 3~
connection.
