4 Mounting

4.1 General notes

Attention!

The following points must be complied with during the mechanical installation to avoid causing a defect
in the device due to assembly errors or environmental influences:

•

Before installation remove the device from the packing and check for any possible shipping
damage!

•

Assemble the device on a clean and stable base. Do not distort during assembly! Use the
appropriate mounting devices for proper installation of the unit!

•

Do not mount equipment on vibrating base!

•

When mounted onto lightweight walls, there must be no impermissibly high vibrations or shock
loads. Any banging shut of doors that are integrated into these lightweight walls, can result in
extremely high shock loads. Therefore, we advise you to decouple the devices from the wall.

•

Do not allow drilling chips, screws and other foreign bodies to reach the device interior!

•

The device should be installed in a location where it will not be disturbed, but at the same time
can be easily accessed!

•

Depending on the housing model use supplied stoppers for cable inlets, cut off necessary cable
inlets respectively to the cable diameter. Or alternative use cable inlet for cable glands. Any
cable ducts openings not used must be sealed!

•

Care must be taken to avoid direct radiation from the sun!

•

The device is designed for vertical installation (cable inlet down). A horizontal or reclined
installation is only permissible after technical release of the manufacturer!

•

Be sure to observe proper heat dissipation (

Technical data, heat dissipation).

4.2 Minimum space requirement

In order to ensure sufficient ventilation of the device, clearance on all sides of at least 50 mm has to
be maintained to the housing walls, switch cabinet doors, wiring ducts, etc. The same clearance
applies to the installation of several devices next to each other.
When installing several devices on top of each other, the danger of reciprocal heating exists. This
layout is only then permissible when the air suctioned from the upper unit does not become warmer
than the permissible ambient temperature (

Technical data). I.e., a correspondingly larger clearance

or thermal shielding is required.

4.3 Outdoor installation

Outdoor installation is possible up to -20 °C when the controller supply is not switched off. Installation
must be protected from the effects of weather as much as possible, including protection from direct
sunlight!

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.

•

It is forbidden to carry out work on electrically live parts.

•

A second person must always be present when working on energized parts or lines who
disconnects in case of emergency.

•

Inspect electrical equipment periodically: retighten loose connections – immediately re­place damaged lines and cables.

•

Always keep switch cabinets and all electrical supply facilities locked. Access is only
allowed for authorized persons using a key or special tool.

•

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 required protective earth connection is established using screws between the hous­ing parts in metal terminal space covers and housing casings. Commissioning is only
permissible after these screws have been properly attached!

•

Metal screwed-connections are not permitted in plastic housing parts because there is
no potential equalization.

•

Never clean electrical equipment with water or similar liquids.

Information

The respective connections are represented in the enclosure of this manual (

Connection diagram)!

5.2 EMC-compatible installation

5.2.1 Motor cable

The applicable standard for interference emissions is EN 61000-6-3. Compliance with this standard is
achieved through the use of an unscreened motor feed cable.

5.2.2 Signal cable

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 control unit with the protective ground (keep cable short and with as little inductance as
possible!).

5.2.3 Harmonics current for devices ≤ 16 A

According to EN 61000-3-2 the devices are to be classified as “professional” devices. The application
is therefore limited to use by trade, certain vocations or industries.
Connection to a low voltage supply (public networks) is allowed insofar as this has been clarified with
the respective energy supply company responsible.
Note: up to a maximum current of approx. 4 A, the limits are adhered to with no restrictions.
Exception for Germany: An energy provider follows the technical connection conditions of the
TAB2007, in which case the use of phase angle controlled devices up to a rating of 3.4 kVA per phase
is allowed.

5.3 Mains connection

Power from the mains is connected to terminals: PE, L1 and N. Here, it must be strictly observed that
the mains voltage lies within the allowable tolerance specifications (

Technical data and nameplate

affixed to the side).

Danger due to electric current
The mains voltage must comply with the DIN EN 50160 quality characteristics and the defined
standard voltages in IEC 60038!

5.4 Motor connection

The motor is connected at terminals U1 and U2. Several motors can be connected to the device.

Attention
The maximum total control current (specified for electronic voltage regulation) for all motors
may not exceed the device’s rated current.
If the maximum control current for electronic voltage regulation is not known, a supplementary
20% of the rated motor current must be allowed for.
When controlling motors from other manufacturers, the controllability and the maximum
current for electronic voltage regulation should be requested from the manufacturer.

Information

It is recommended that a separate motor protection unit be foreseen for each fan.

5.4.1 Running noise

When controlling ventilators using electronic voltage regulators, motor noise can occur (due to the
system), which can be troublesome.
On fast running ventilators with a high level of air noise, this noise is relatively low. On slow running
ventilators with a low level of air noise, this noise may be dominant in the lower speed range due to
the occurrence of resonance.

5.5 Motor protection

The motor can be protected by connecting thermostats “TB”.
When multiple motors are connected, it is essential to ensure that thermostats “TB” are always
connected in series.
If a connected thermostat is tripped (break between the two terminals “TB”), the device is switched off
and is not switched back on.
Relais “K1” is de-energized, terminals “11” - “12” bridged. The signal lamp flashes in code

|2|

(

Diagnostics / faults).

Possibilities for re-starting after the drive has cooled down (terminals “TB” bridged) by:

•

By switching the mains voltage off and then on again.

•

Via a digital input for remote control (ON / OFF enable).

Attention!

•

An outside voltage may never be connected to the terminals “TB”!

•

If a bypass circuit is installed, or in the “100 %” position on devices with a main switch, the motor
protection inside the controller has no function. In this case, additional motor monitoring may be
required.

5.6 Signal or sensor connection (E1 = Analog In 1)

The unit has one-analog input: terminals “E1” / “GND” (Analog In 1).
The connection is independent of the programmed operating mode and from the sensor signal
employed.
The internal jumpers must be placed in correct position depending on input signal. Factory setting 0 ­10 V.

•

When connecting passive temperature sensors TF.. (KTY81-210) must be paid attention to no
polarity.

•

When connecting active sensors attention must be paid to correct polarity, a 24 V DC power
supply is integrated.

Technical data and connection diagram).

For operation the relay is energized, terminals “12” and “14” are bridged. For fault the relay is de­energized, terminals “11” and “12” are bridged (

Diagnostics / faults).

•

Fault indicated for: line fault, blown internal semiconductor fuse, broken controller-internal
voltage supply, overheating by the motor (thermostats “TB” connected).

•

By sensor failure (only in P-Control or PI-Control operation

2.01 , 3.01 , 4.01 ) message only via

flash code of signal lamp (code

|3|

), the relay remains energized.

•

When switching off via enable (D1 = Digital In 1), the relay remains energized.

5.11 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 50V (between “GND” terminals and “PE” protective earth). If necessary, a
connection to the protective earth potential can be established, install bridge between “GND” terminal
and the “PE” connection (terminal for screening).

Signal fault

Function only for operation as P-Control­ler, PI-Controller (

2.01 )!

Interruption or short circuit in the sensor
leads or sensor values measured are out­side measuring range:

- For temperature sensors TF.. (KTY)
below approx. -26 °C and above approx.
76 °C

- For active sensors with reaching mini­mum or maximum signal values (depend­ing on selected signal type).

The device works with minimal or maxi­mum modulation depending on whether
there is a short-circuit or an interruption,
and on the programmed mode of opera­tion.

The controller functions automatically
again with the value measured at the
temperature sensor after the fault has
been rectified.

Check sensor.

11.1.1 Performance reduction during elevated ambient temperatures

The maximum permissible ambient temperature for the devices is 40 °C. Up to this temperature,
loading (maximum continuous current) with the specified rated current is possible.
The removal of heat in the unit due to power dissipation is dependent on the ambient temperature, so
the maximum load has to be reduced if the ambient temperature is higher than 40 °C! For each degree
higher the load has to be reduced approx. 2.2 %.
The average value measured during a 24 h period must be 5 K under the max. ambient temperature.
For installation in a switch cabinet, the device’s dissipation and its possible affect on the ambient
temperature must be taken into consideration (

Technical data)!
