4 ASSEMBLY, INSTALLATION AND COMMISSIONING
4.1 General information regarding the installation and operation
ATTENTION! • Do not lay cables for inputs next to lines carrying voltage.
• Avoid heavy vibrations, aggressive gases, heavy soiling
and damp.
NOTE • Before connecting the device, check that the power supply
corresponds to the values shown on the rating plate.
• Pay attention to the maximum load of the relay contacts
(see Chapter Technical data ).
• Ensure that you install all sensors with sufficient separation
from lines carrying voltage, in order to avoid incorrect
temperature measurements and to protect the device from
voltage interference over the sensor inputs.
Fig. 4.1: Installation
Panel Mounting frame
4.2 Assembly
The devices are designed for panel mounting in a 71 x 29 mm cutout, and are
secured using a mounting frame.
The ambient temperature for problem-free operation lies in the range from
0 ... + 60°C.
Ensure sufficient ventilation through the cooling slots.

Panel Mounting frame
Front seal
4.3 Electrical connections
Use cable with a cross-section of max. 2.5 mm2.
Check the auxiliary power before connection the voltage supply
(see Chapter Technical data ).
Do not load the relay contacts higher than permitted. If necessary, use a
contactor.
SENSOR CONNECTIONS
Mount the tips of the sensors pointing upwards. This will prevent the
collection of liquids or condensate.
Do not mount the room sensors in an airflow. This could lead to incorrect
measurements of the average room temperature.
