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! Start-up is not allowed in the case of transport damage!
•At a weight greater than 25 kg for men / 10 kg for women, the device should be lifted out by two
persons (according to REFA). The values may differ from country to country.
•Wear safety shoes and gloves for handling!
•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!
•A mounting on vibrating base is not permissible, if no data to the vibration strength is made (see
Technical data)!
•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!
•Maintain the stated minimum clearances to ensure unobstructed cooling- air feed as well as
unobstructed outgoing air discharge (
minimum space requirement)!
•The device should be installed in a location where it will not be disturbed, but at the same time can
be easily accessed!
•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 (see 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 (see Technical data). I.e., a correspondingly larger clear-
ance or thermal shielding is required.
4.3 Fastening the device
The type of fastening and the number of fastening points are dependent on the housing design. All the
fastening points available must be used for safe fastening.
Proceed as follows:

controller at room temperature!
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.
•Other measures may be necessary to achieve safe electrical isolation.
•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.
•For metal cable inlets the necessary protective earth connection to the bottom of the housing is
made by screws. The device may only be started up when these screws are fitted properly.
•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.
•The device owner is responsible for the EMC of the entire plant according to the locally applicable
standards.
•Never clean electrical equipment with water or similar liquids.

5.3 EMC-compatible installation
5.3.1 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.
5.3.2 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 control unit with the protective ground (keep cable short and with as little inductance as
possible!).
5.4 Mains connection
5.4.1 Line voltage
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).
A connection between two phase conductors is possible for 3 ~ 230 V supply networks.
Attention!
To activate the on current limitation, you must wait at least 90 seconds after switching off the line
voltage before switching back on!
5.4.2 Line protection fuse
The mains connection must be fused depending on the used cable, the type of routing, the operating
conditions and according to the standards applicable on site. The specification for the maximum
admissible line fuse of the device must be observed (see technical data).
Possible components for the line protection (recommendation):
•Safety fuses of operating class “gG” (whole range fuse cartridges for general applications according
to EN 60269-1).
•Line protection switch with characteristic “C” (according to EN 60898-1).
•Motor protection switch with overload and short-circuit trigger (according to EN 60947-4-1). Setting
overcurrent trigger to maximum permissible current of the line.

5.4.3 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!
5.4.4 Leakage current, securely attached, protective earth conductor
Danger due to electric current
The maximum leakage current depends on the type of device and the connected mains voltage (
Technical Data). With regard to fixed connection and the type of PE conductor connection, the
specification for the leakage current must be observed under consideration of the locally valid
standards (for Europe
EN 50178 Section 5.2.11 or 5.3.2.1 etc.).
Minimum cross-section for PE conductor for fixed connection 1.5 mm

!
5.5 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).
5.6 Inverter output
5.6.1 Motor connection
The motor leads are connected to the terminals: U1, U2. Several fans can be connected to the
controller-the maximum total current of all motors must not exceed the current rating for the controller.
Change direction of rotation
wiring diagram fan!
Information
•It is recommended that a separate motor protection unit be foreseen for each fan.
•For motors with thermistors “TB” e.g. type S-ET10.
5.6.2 Disconnection between controller and motor (repair switch)
Ideally, a repair switch should be installed before the controller (supply line disconnect).
In the case of complete disconnection (entire load) after the controller, the enable (controller OFF /
ON) must be disconnected simultaneously. I.e., an additional control contact is needed. Switching on
the motor while simultaneously issuing the enable (ON) achieves secure energizing with low satura-
tion of the controller. For this a programming is necessary (
IO Setup Enable ON / OFF).
Attention!
When switching on the motor plus existing release: under certain circumstances, this can occur under
full modulation of the controller.
5.7 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 - TB”), the device is
switched off and is not switched back on. Programmed operating and fault signaling relays are
activated.

Motor fault
Display during motor fault
Possibilities for re-starting after the drive has cooled down (terminals “TB” bridged) by:
•By switching the mains voltage off and then on again.
•By simultaneously depressing the three keys: P, ▲, ▼(if a fault is indicated).
•Via a digital input for remote control (ON/OFF release) (
IO setup – Digital inputs).
Attention!
•An outside voltage may never be connected to the terminals “TB” and/or!
•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.
5.8 Signal input or sensor connection (E1, E2)
The unit has two analog inputs: Analog In 1 “E1” and Analog In 2 “E2”
The connection is independent of the programmed operating mode and from the sensor signal
employed.
•When connecting passive temperature sensorsTF.. (KTY81-210) or PT1000 at terminals “E1” and
“T” or “E2” und “T” must be paid attention to no polarity.
For a high interference immunity a capacitor must be connected directly to the sensor (1 nF
parallel). With temperature sensors type TF.. (KTY81-210) a capacitor is integrated.
•When connecting aktive sensors at the terminals “E1” and “GND” or “E2” and “GND” attention must
be paid to correct polarity, a 24 V DC power supply is integrated.
• For sensors in two-wire-technology (4 - 20 mA signal), the connection is made on the “E1” and
“24 V” or “E2” and “24 V”, “GND” terminal is omitted.
Danger due to electric current
Never apply line voltage to analog inputs!
5.9 Output voltage 0 - 10 V (Analog Out)
The unit has two analog outputs “A1” and “A2” (I
max
6 mA).
The outputs “A1” (0 - 10 V) can be allocated with various functions (
IO Setup: Analog output “A”).
Connection to terminal “A1” - “A1” “Analog Out 1”.
Output “A2” constant voltage +10 V e.g. for external potentiometer. Connection to terminals “A2” -
“GND” “Analog Out 2”.
It is not permissible to connect outputs of several devices to each other!
5.10 Voltage supply for external devices (+24V, GND)
A voltage supply is integrated for external devices e.g. a sensor (max. current load see technical
data).
In case of overload or short circuit (24 V – GND), the external power supply is shut down (multi-fuse).
The device performs a “Reset” and continues operation.
•It is not permissible to connect voltage outputs of several devices to each other!
•It is not permissible to connect voltage outputs in the device to each other!

> 100 kΩ) for external Set point
•1x output 0 - 10 V (I
max
10 mA)
•3x digital-inputs, Activation via floating contacts
•2x relay outputs (contact load 2 A 250 V AC)
5.12 Connection of external Terminal type AXG-1A(E)
An external terminal is required for starting-up and setting-up versions that do not have an integrated
terminal.
•Model AXG-1A, Part-No. 349034 for wall mounting
•Model AXG-1AE, Part-No. 349008 for panel mounting
Connection Terminal Type
AXG-1A(E)
The connection is made via a 4-strand line at the terminals of plug (D-, D+, GND and
+24 V).
e.g., telephone flex e.g. J-Y (St) Y 2x2x0.6 (or similar), maximum line length ca. 250 m.
- Voltage supply: Terminal “24 V”, “GND”, (I
max
, for terminal approx. 50 mA)
- Signal “D+” and “D-” (RS 485)
If the Modbus
®
interface is used for network a “Z-Modul-A” (Part.-No. 380054) is necessary to use an
external terminal at the same time.
5.13 Digital inputs (D1, D2)
Different functions can be assigned to the digital inputs “D1”and “D2” (see IO Setup: Functional
overview of digital inputs). Activation via floating contacts, a low voltage of approx. 24 V DC is
connected.
Danger due to electric current
Never apply line voltage to the digital input!
Note the input resistance (see technical data).
5.14 Relay outputs (K1, K2)
Various functions can be allocated to the relay outputs “K1” and “K2” (
IO Setup: function and
inverting relais outputs). Max. contact rating
technical data and connection diagram.
Relays K1
•Connection of the floating contacts of relay “K1” to the terminals 11, 14, 12.
•“K1 Function” factory setting:
| 1K | Operating indication. I.e. energized for operation without
fault, for enable “OFF” de-energized.
Relays K2
•Connection of the floating contacts of relay “K2” to the terminals 21, 24, 22.
•“K2 Function” factory setting:
| 2K | Fault indication. I.e. energized for operation without fault and
for enable “OFF”.

5.15 Communication
5.15.1 Networking via MODBUS-RTU
The device comes equipped with a RS-485 interface for networking via MODBUS. Conntection at: “A
(D+)”, “B (D-)” and “GND”.
The address must be set in the “IO Setup”menu.
Information
A maximum of 64 members can be directly connected to one another, and another 63 members via a
repeater.
5.15.2 RS-485 - network design and interface parameter
Please ensure the correct connection; i.e. "A (D+)" must always be connected to "A (D+)" of the next
devices. The same applies to "B (D-)" .
In addition, a "GND" connection must be established, as dissimilar potential (over 10 V!) will lead to
the destruction of the RS-485 interface (e.g. lightning).
general example for MODBUS device connection
The data line must be connected from one device to the next. No other type of wiring is allowed!
Always use only two wires of one lead (twisted pair) for the connection.
Example for MODBUS connection
Recommended wire types
1. CAT5 / CAT7 cables
2. J-Y (St) 2x2x0.6 (telephone wire)
3. AWG22 (2x2 twisted pair)
When using telephone flex with four cable cores, we recommend the following allocation:
“A (D+)” red, “B (D-)” black, “GND” white
Information
•Pay attention to sufficient distance from powerlines and motor wires (min. 20 cm).
•Except the data link "A (D+)", "B (D-)" and "GND"- connection may no further cable cores of the data
line be used.
•Max allowed wire length 1000 m (CAT5/7 500 m).
Shielding
The use of shielded cables is normally not demanded but offers high protection against electro-
magnetic interferences, especially high frequencies. However, the effectiveness of the shield depends
on careful installation of the line.
If shielded cables are used, the shield should be placed at “PE” on at least one side (preferably on the
master connection). The occurrence of compensating currents may have to be considered if the shield
is contacted on both sides.

Information
If any matters are unclear, please contact our V-STE support department for control systems -
ventilation technology. The information sheet "Network structure of MODBUS" R-TIL08_01 contains
detailed information about "MODBUS".
5.15.3 LON
®
Bus system is possible via add-on module
Connection to the LON® bus system is possible via add-on module type “Z-Modul-L” (Part-No.
380053). Communication to controller via the RS-485 interface, FTT-10A transceiver.
5.16 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” 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).
5.17 Bypass circuit
Please observe the following during bypass switching (controller shunt with mains voltage):
•Mutual locking of mains contactor and bypass protection.
•Time delay of at least 1 second during switching.
•When the contactor is switched off at the inverter output, the “enable” (ON / OFF) must also be
opened and closed again when it is switched back on. When switching off, wait at least 90 seconds
before switching back on!
•Never apply line voltage to the inverter output!
