3.4 Temperature management
The service life of devices with power electronics is decisively dependent on the ambient temper-
atures. The longer electronic components are exposed to high ambient temperatures, the faster the
deterioration and the more probable the failures.
The power electronics protects itself against excessive temperatures by active temperature manage-
ment (power reduction).
However, this cannot provide complete protection in all circumstances. Observe the rated data -
particularly the maximum permitted ambient temperature - on the rating plate.

4.3 Connection lead & terminal box
Information
In demanding environments (wet areas, open air installation) all connections must incorporate water
drainage curves. To ensure that water cannot penetrate through to the controller housing from the
connections install a terminal box lower than the motor.
4.4 Assembly in a humid atmosphere
Information
If the device is not in use for longer periods in a humid atmosphere, it is recommended to operate the
motor/fan for at least two hours every month at 80 - 100 % of maximum speed to remove any moisture
that has penetrated inside.
4.5 Motorheating
A continuous power supply is required for safe operation down to the minimum permitted ambient
temperature (see technical data).
If the motor is not switched on with an existing power supply (no setting signal, switch off by enable),
the motorheating switches back off automatically at a controller inside temperature of -19 °C and
heating up to -15 °C.
Heating takes place via the motor winding whereby a current is induced which cannot cause rotation.
4.6 Behaviour in rotation by air current in reverse direction
In the STOP state (no preset signal, no voltage supply) the motor controller does not intervene when
the motor / fan turns in the wrong direction (e.g. due to a draught).
If the motor / fan is started ( voltage ON), while being driven in the opposite direction to that set, the
speed is reduced controlled to “0” and restarted in the set direction of rotation.
The higher the speed to be reduced, the longer this process lasts.
In cases in which the motor / fan is driven very powerfully in the wrong direction, it may not be possible
to start the motor / fan with the set direction of rotation.
Information
•Do not switch off line voltage that the motor / fan can start again!
•Safe starting of motors / fans is not guaranteed if it is started in reverse. If the application demands
safe starting, the machine manufacturer or owner must prevent reverse driving rotation by suitable
measures.

5 Electrical installation
5.1 Safety precautions
Danger due to electric current
•Work on electric components may only be carried out by trained electricians or by persons
instructed in electricity under the supervision of an electrician in accordance with electrical
engineering regulations.
•The 5 electrical safety rules must be observed!
•It is forbidden to carry out work on electrically live parts! Even after disconnection, the dc-link is still
live. Always wait at least 3 minutes.
•Cover neighbouring electrical equipment during installation work.
•Cable glands made out of metal are not allowed in plastic terminal boxes due to lack of potential
equalisation.
•Other measures may be necessary to achieve safe electrical isolation.
•Connect fan only to electrical circuits that can be disconnected with an all-pole isolating switch.
•Operating the device with the housing cover removed is prohibited because energized, exposed
parts are present inside the device. Disregarding this regulation can lead to severe personal injury.
•The final application must ensure that the fundamental health and safety requirements are met.
•The device owner is responsible for the EMC of the entire plant according to the locally applicable
standards.
•Electrical equipment must be checked regularly: Loose connections are to be re-tightened and
damaged lines or cables must be replaced immediately.
5.2 EMC-compatible installation
5.2.1 Harmonics current
The device is classified as "professional equipment" in accordance with EN 61000-3-2 due to
unknown system conditions, the operation of multiple built-in components in the end device (e.g. air
handling unit) and unknown impedances at the connection point which affect the harmonics current.
Connection to the low voltage supply (public networks) is allowed insofar as this has been clarified
with the respective energy supply companies responsible.
Input impedance can be used if necessary to meet the limit values for harmonics current without
restriction (accessory is available according to the system conditions).
5.2.2 Control cables
Pay attention to sufficient distance from powerlines and motor wires to prevent interferences. The
control cable may not be longer than 30 m. Screened control cables must be used when the cable
length is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e.
only to the signal source with the protective earth (keep cable short and with as little inductance as
possible!).
5.3 Voltage supply
5.3.1 Line voltage
Connection line voltage to: PE, L1, and N. Here, it must be strictly observed that the line voltage lies
within the allowable tolerance specifications (see technical data).
Danger due to electric current
•The fan / motor is to be used exclusively as a built-in component. The connecting cable (power
supply connection) should therefore be viewed as an internal cable. A direct mains connection is not
allowed.
•Between the voltage supply of the device and the protective earth “PE” is in no case a higher voltage
permissible than the indicated line voltage of the device!
•To activate the on current limitation, you must wait at least 90 seconds after switching off the line
voltage before switching back on!

5.3.2 Required quality attributes for the mains voltage
Danger due to electric current
The mains voltage must comply with the EN 50160 quality characteristics and the defined standard
voltages in IEC 60038!
5.3.3 Operating in IT-System
Danger due to electric current
•In the IT-System the neutral point of voltage supply is not grounded; in the case of a short-circuit
between a phase (e.g. “L1”) and protective earth “PE” becomes the protective earth potential
phase.
•Between the connection of the voltage supply of the device and the protective earth “PE” is in no
case a higher voltage permissible than the indicated line voltage of the device!
1 ~ types can be used in IT-System in standard version. These may only be used in 3 ~ IT-Systems if
no higher voltage to the “PE” can occur than the specified mains voltage of the device even in case of
a fault to earth of a mains phase which is not used by the device (of none of the two power supplies).
In order to ensure a trouble free operation in IT-System the “GND” potential of the control ports have
to be connected with the protective earth potential.
As a consequence of these connection must be considered for the control ports (exception floating
relay contacts):
1. Connection only with wires, suitable for mains voltage and surrounding area.
2. Connection with suitable isolated amplifiers only.
5.4 Residual-current-operated protective device
Danger due to electric current
To ensure as high a degree of reliability as possible we recommend a release current of 300 mA,
where a residual current circuit breaker (type A) is used.
Residual current circuit breaker (type A)
Exception: All-current-sensitive fault current circuit breaker on the 3 ~ 230 V line
When connecting the device between two outer conductors, “all-current-sensitive” fault current circuit
breakers must be used (see EN 50 178, Art. 5.2).
5.5 Motor protection
Integrated overload protection, preceding motor protection device unnecessary (max. line fuse see
Technical data).

5.6.3 Specification signal/speed characteristic curve
In “Constant speed” mode, the motor speed is proportional to the specification signal.
This is an example - other operating modes/characteristic curves are possible by agreement.
Characteristic curve: Motor speed proportional to specification signal
n Motor speed
100 % rated speed motor maximal Speed
E1 Min. Internal offset for analog input E1
Si Speed setting signal 0...10 V / 0...100 % PWM
* If the internal setting "E1 min." (factory setting 5 %) is exceeded by 0.15 V, the system starts the
motor with a factory set minimum speed depending on the motor type(typically 9 % of the reference
speed).
If the specification signal has exceeded the value corresponding to the minimum speed, the motor
speed is proportional to the specification signal.
5.6.4 Voltage supply “10 V DC”
Voltage supply for external components, e.g. for a potentiometer for speed setting (SELV current
source according to EN 60204-1).
Connection: “10 V” - “GND” (max. load see Technical data und connection diagram).
During an overload or short-circuit (10 V - GND), the control voltage is disconnected . Automatic start
after elimination of the cause of error.
It is not permissible to connect outputs of several devices to each other!
5.6.5 Tacho-output “A1”
Via the Open-Collector output “A1” the current motor speed can be output (further
specifications for “A1”see Technical data).
The frequency (duty cycle 50 : 50) that can be measured by a pull-up resistor at
the output “A1” corresponds to the motor speed.

5.6.6 Potential at control voltage connections
The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts
are potential free). There is a potential separation between the control voltage connections and the
protective earth. It must be ensured that the maximum external voltage at the control voltage
connections cannot exceed 50 V (between “GND” and “PE” protective earth). If necessary, a
connection to the protective earth potential can be established (bridge between “GND” and “PE”).

6 Start-up
Attention!
•Before first-time start-up, check the following:
1. Installation and electrical connection have been properly completed?
2. Connection data complies with the specifications on the rating plate?
3. That any installation remnants and foreign bodies that may be present have been removed?
Attention!
•Start-up may only begin when all safety instructions have been verified and any hazards have been
ruled out.
–Check direction of rotation.
–Check for quiet, low vibration operation. Strong vibrations due to erratic operation (unbalanced),
e.g. caused by transportation damage or improper use, can lead to failure.
