prioAir equipped with an EC motor
The fans are driven by EC motors. These motors are delivered with a pre-wired potentiometer (0–10 V) that allows you
to easily find the required working point of the fan. All motors are suitable for 50/60 Hz. The input voltage for single-
phase units can vary between 200 and 277 V. All models have one potential-free terminal for error message.

9.5 Residual current circuit breaker
All-current-sensitive residual current circuit breakers are required for use in alternating-current systems with 50/60 Hz,
in combination with electronic devices such as EC motors, frequency converters or uninterruptible power supplies
(UPS).
9.6 Protecting the motor
Note:
In fans equipped with an EC motor, there is no additional motor protection needed. The motor protection is
integrated in the electronics of the motor.
Important
Damage to motor due to overcurrent, overload or short circiut.
♦Lead-out temperature monitors must be integrated in the control circuit in such a way that, if a fault
occurs, the motor cannot switch on again automatically after it has cooled down.
♦Motor lines and temperature monitor lines should be laid separately on principle.
♦Without thermal protection: Use a motor protection switch!

14 | Cleaning
12.3 Maintenance
Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is
provided.
We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are
specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning,
replacing defective components or other corrective measures. For traceability reasons, a maintenance plan must be
created which documents the work carried out. This must be created by the operator. If the operating conditions are
"extreme", the maintenance intervals must be reduced so that maintenance is carried out more frequently. Examples
of extreme operating conditions:
• Ambient temperature > 40 ºC or < 0 ºC, or temperature fluctuations > 20 K
