• Installation works may be performed only by trained and qualified personnel.
• The devices have rotating parts and are connected to the electricity. This may pose a risk to the human health and life. That is why safety
requirements have to be followed while installing. If you have any doubts on the safety of the products installation and use, please contact the
manufacturer or its representative.
• Make sure that the electric power chain data complies with the data on the product label on the device case.
• In order to operate, the equipment must be connected to a power supply and 0-10V speed controller device according connection diagrams of
the specific model.
• Selected power cable has to match device power. It is connected to the electrical terminals X1 ( Fig . 1 ) or to the breaker ( available as an ac
-
cessory and mounted installer) . Control and power supply terminals of the cross-section area - 2.5 mm2.
• Fan 0-10 VDC control is connected to the electrical box terminals X1 ( Fig . 1 ) .
• Electricity is connected in accordance with current regulations.
• need to prevent water entering into the connection box.
• Use cables that comply with the currents , the stickers .
• Power Switch dry conditions

• The fan has to be connected according to the electric scheme which is described in this document and is shown under the electricity connection
switch cap.
• Before turning on, it is necessary to make sure that the electricity scheme in this document coincides with the scheme indicated under the
electrical circuit box cover. If they do not match, it is strictly prohibited to turn the device on and it is necessary to contact the manufacturer or its
representative.
• The device must be connected to the power supply using the security features, for example, an automatic switch.
• Make sure that the grounding wire is connected.
• It is necessary to ensure minimal engine speed at which the reverse thrust valves (if any) open.
