4. TRANSPORT & STORAGE

Correct transport, storage, erection and mounting, as well as careful operation and maintenance are essential for proper and safe operation of the equipment.Protect the fan against physical shocks and vibration during transport and storage. Also, be sure to protect it against water (rainfall) and excessive temperatures.

WARNINGWARNING

If the fan must be subject to long-term storage, the storage time without application of any power supply shall not exceed two years since fan production or since operating the fan for at least half-an-hour continuously. The storage site shall have a temperature between -20°C and +70 °C, a Relative Humidity lower than 75%, and not be subject to condensation or exposed to dust.

These connections are carried out by Nicotra Gebhardt and cannot be modified by the end user.

WARNINGWARNING

9. INSTALLATION

The fan installation must be carried out only by competent and qualified staff.

9.1 Commissioning

Work on the device/system by unqualified personnel or failure to comply with warnings can result in severe personal injury or serious damage to material.Only suitably qualified personnel trained in the setup, installation, commissioning and operation of the product should carry out work on the device/system.The FDP fan must be grounded through the PE connector on the driver.The following terminals can carry dangerous voltages even if the driver is inoperative:• the power supply terminals L, N or R, S, T• the motor terminals U, V, W

WARNINGWARNING

In the final installation, the device shall be directly connected to the supply terminals and shall have a contact separation in all poles, providing full disconnection under overvoltage category III conditions.

WARNINGWARNING

Rev. 0 - 11/12/2020


16/40

9.2 Operation

Ensure correct grounding connections. The ground cable must be enough to carry the maximum supply fault current which nor-mally will be limited by the fuses or MCB. Suitably rated fuses or MCB should be fitted in the main supply to the driver, according to any local legislation or codes.

WARNINGWARNING

The driver operates at high voltages.Certain parameter settings may cause the driver to restart automatically after an input power failure.

CAUTIONCAUTION

9.3 Ambient operating conditions

The installation place must be in accordance with the IP protection degree of the fan. In this respect, refer to the ID plate de-scribed in chapter 3.

Humidity Range: 90% non-condensingAltitude: if the fan is to be installed at an altitude > 1000m, derating is required.Shocks: do not drop the fan or expose it to sudden shock.Vibration: do not install the fan in an area where it is likely to be exposed to constant vibrations.

CAUTIONCAUTION

9.4 Fan installation

Before carrying out any intervention on the electrical system, disconnect the power supply by means of main switch.

Make sure that a differential switch (circuit breaker) has been installed upstream the line and that it functions properly.

Work on the driver/fan by unqualified personnel or failure to comply with warnings can result in severe personal injury or serious damage to material.Only suitably qualified personnel trained in the set-up, installation, commissioning and operation of the product should carry out work on the driver/fan. This driver must be grounded.The power supply terminals L, N (1-Phase) and the motor terminals U, V, W can carry dangerous voltages even if the driver is inoperative.

14.2 Motor overheating: THERMAL PROTECTOR

The Motor Winding temperature and the driver derating are dependent on the fan size and on the fan working point. Therefore, it is possible that the fan could work at 50°C without a performance limitation.

The Driver and motor areas are rated for operating in a temperature range between -20°C and +40°C. The derating is tested and guaranteed from +40°C to +50°C. Higher temperatures could damage the motor winding or the performance could be significantly reduced.

AfreewaresoftwareisavailableonNicotra Gebhardtsite(http://www.nicotra-gebhardt.com)formonitoringthefan.Pleaserefertotherelatedmanualformoredetails

The software can be used for configuring the fan and monitoring the performance. The performance is estimated through an algorithm and, therefore, subjected to variable tolerance depending on the working point, airflow stability and the constant algorithm resolution itself.
