conneconsofthemotorcabletothedriverboardaremadeasshowninthefollowinggure.
Theactualposionofthemotorconneconsontheprintedcircuitboardmaydier,betweendierentdrivermodels.
These connecons are carried out by Nicotra Gebhardt and cannot be modied by the end user.
WARNINGWARNING
9. INSTALLATION
The fan installaon must be carried out only by competent and qualied sta.
9.1 Commissioning
Work on the device/system by unqualied personnel or failure to comply with warnings can result in severe personal injury or
serious damage to material.
Only suitably qualied personnel trained in the setup, installaon, commissioning and operaon 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 inoperave:
• the power supply terminals L, N or R, S, T
• the motor terminals U, V, W
WARNINGWARNING
In the nal installaon, the device shall be directly connected to the supply terminals and shall have a contact separaon in all
poles, providing full disconnecon under overvoltage category III condions.
WARNINGWARNING

9.2 Operation
Ensure correct grounding connecons. 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 ed in the main supply to the driver, according
to any local legislaon or codes.
WARNINGWARNING
The driver operates at high voltages.
Certain parameter sengs may cause the driver to restart automacally aer an input power failure.
CAUTIONCAUTION
9.3 Ambient operating conditions
The installaon place must be in accordance with the IP protecon degree of the fan. In this respect, refer to the ID plate de-
scribed in chapter 3.
Humidity Range: 90% non-condensing
Altude: if the fan is to be installed at an altude > 1000m, derang is required.
Shocks: do not drop the fan or expose it to sudden shock.
Vibraon: do not install the fan in an area where it is likely to be exposed to constant vibraons.
CAUTIONCAUTION
9.4 Fan installation
Placethefanaccordingtoyourneeds,aerhavingcheckeditsdimensionsandtheposionofthexingholes.
The driver must NOT be removed from the related FDP fan type and size.
The driver cannot be used separate from the related fan.

Before carrying out any intervenon on the electrical system, disconnect the power supply by means of main switch.
Make sure that a dierenal switch (circuit breaker) has been installed upstream the line and that it funcons properly.
Work on the driver/fan by unqualied personnel or failure to comply with warnings can result in severe personal injury or serious
damage to material.
Only suitably qualied personnel trained in the set-up, installaon, commissioning and operaon 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
