Make sure that a differential switch (circuit breaker) has been installed upstream the line and that it
functions properly.
Before carrying out any intervention on the electrical system, disconnect the power supply by means
of main switch.
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) or R, S, T (3-Phase) and the motor terminals U, V, W can carry
dangerous voltages even if the driver is inoperative.

RDP 1.05kW 1-Phase
Single Phase 220/240V ±10% @ 50/60Hz
The performance in the range [200V-264V] @ 50Hz/60Hz is always the
same due to the PFC module inside the driver.
RDP 2.1kW 1-Phase
Single Phase 220/240V ±10% @ 50/60Hz
The performance in the range [200V-264V] @ 50Hz/60Hz is always the
same due to the PFC module inside the driver.
Min. and max. wire section:
Spring-loaded push-in clamp, suitable for
• 0.2 mm² - 24 AWG up to 2.5 mm² - 12 AWG (stranded) or 4 mm²
(solid) wire
Use a bladed screwdriver, 0.6x3.5 mm max, to unlock.
RDP 2.65kW - 5.5kW 3-Phase
Three Phase 400V ±10% @ 50/60Hz
The maximum fan performance, within the nominal range of
supply-voltage [360-440V], may be sensitive to the actual supply
voltage. Whether the fan maximum speed is related to the supply
voltage depends on the fan size and duty point.
Min. and max. wire section:
Spring-loaded push-in clamp, suitable for
• 0.2 mm² - 24 AWG up to 6 mm² - 8 AWG (stranded) or 10
mm² (solid) wire
Use a bladed screwdriver, 0.6x3.5 mm max, to unlock.
As concerns the cable minimum section, check the requirements issued by the country of installation.
