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!
4.4 Installation location for agriculture
When using for animal keeping, do not install the device directly in the stable but in a separate room
with a lower pollutant load. This helps to avoid damages caused by pollutant gases (e.g. ammonia
fumes, hydrogen sulphide fumes).
4.5 Temperature influences during commissioning
Avoid condensation in the controller and functional faults attributable to condensation by storing the
controller at room temperature!
4.6 Mounting the two fresh air temperature sensors type TFR
Please note the following when mounting the two sensors to measure the supply air temperature:
1. Mount the sensors as far apart as possible, whereby the temperature difference between the
two measuring points should be as low as possible.
2. To avoid extreme temperature peaks, these are not mounted outdoors unprotected but in the
ante-room through which the fresh air is usually drawn.
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.

•Regular function testing of the alarm transmitter is absolutely essential!
5.4 Connection of flashing light
The flashing light e.g. type SG1670 Art. No. 349039 (12 V DC max. 500 mA) is connected to the
terminals “B+” and “B-” (GND).
Pay attention to the correct polarity.
In case of an overload or a short-circuit at the terminals “B+” and “B-” (GND) the power supply is
switched off (multifuse).
Information
The delay times set in the “ALARMcon Setup” are taken into consideration in fault indication!
Attention!
•The line to the flashing light is not monitored. It is therefore imperative to lay it in such a way that it
cannot be damaged!
•Regular function testing of the alarm transmitter is absolutely essential!
5.5 Sensor inputs E1 and E2
The two sensor inputs “E1” and “E2” are pre-programmed for measuring the supply air temperature at
the factory. Their measured values are checked for plausibility for as high operational reliability as
possible!
Danger due to electric current
Never apply line voltage to analog inputs!
•Connection of fresh air temperature sensor 1 to terminals “E1” and “GND”
•Connection of fresh air temperature sensor 2 to terminals “E2” and “GND”
The inputs “E1” and “E2” can be used for cot temperature sensors if required. Reprogramming
Installation menu: E1 E2 mode.

5.6 Voltage supply for external devices (V+, GND)
A power supply is integrated for external devices, e.g. for a temperature sensor add-on module (max.
load current
Technical data).
In case of overload or a short-circuit (V+ - GND), the external power supply is switched off (multifuse).
It is not permissible to connect outputs of several devices to each other!
5.7 Connection of temperature sensor add-on module type ZTG8-L
Only the two fresh air temperature sensors can be connected directly to the alarm device UTE-32A-L.
The temperature values for the cots are measured by separately connected sensors on the add-on
modules or by commonly used sensors of compatible ventilation computers depending on the system
constellation (
structure of the alarm system).
5.7.1 Connection of temperature sensor add-on module to RS485 bus 1
The temperature sensor add-on module no. 1 is connected to the ALARMcon. The connection
terminals “V+”, “GND”, “D+” and “D-” are connected to each other for this.
Temperature sensor add-on module no. 2 is connected to ZTG8-L no. 1, temperature sensor add-on
module no. 3 to no. 2 and so on.
The connection terminals are available in duplicate in the ZTG8-L for this. Further information about
the connection
connection data link via interface RS485 BUS 1.
In case of overload or a short-circuit at terminals “V+” and “GND” the power supply is switched off
(multifuse).
