Connect the mains supply cable as shown in the wiring diagram. For the dimensioning of the line, observe the unit‘s
rating plate and the relevant guidelines. Appropriate protection with correctly dimensioned automatic safety breakers
(circuit protection breaker) must be provided.
If DVN / DVNI series roof fans are placed on the market or operated within the EU, they must be equipped with speed
control. This is only possible by means of frequency converters. Using other speed controls, such as voltage control,
will directly damage the motor.
We offer tested and approved frequency converters as accessories. These are pre-programmed and delivered exactly
matched to the respective engine power and speed.

12.2. Frequency converter
If third-party products are used, the following parameters must be set correctly.
The use of a fault current protection switch is not mandatory. If a fault current protection switch is used, only AC/DC
sensitive RCD protective devices (type B or B+) are permitted.
During operation, electric motors heat up. Under certain circumstances (excessively high ambient or fluid temperatu-
res, heavy contamination, etc.), the motor temperature may exceed the safety limit of the electrically isolated parts.
In order to avoid engine damage, various types of temperature monitoring are possible, of which at least one must be
installed on site:
■
Monitoring of the thermal motor current via a FU
■
Motor protection switch

Even when the device is switched off, voltage is applied to terminals and connections. Do not touch the
device for 5 minutes after all-pole disconnection from the mains.
