1.2 Safety Instructions
1.2.1 General Safety Instructions
The device and mainly the filter cap shall not be exposed to unnecessary mechanical stress.
When replacing the filter cap make sure not to touch the sensing elements.
The device must be operated with the filter cap on at all times.
Installation, electrical connection, maintenance and commissioning shall be performed by qualified
personnel only.
Use the EE160 only as intended and observe all technical specifications.
Do not use EE160 in explosive atmosphere or for measurement of aggressive gases.
Do not apply the nominal voltage to the RS485 data lines.
This device is not appropriate for safety, emergency stop or other critical applications where device
malfunction or failure could cause injury to human beings.
1.2.2 Intended Use
The EE160 is intended for the humidity (RH) and temperature (T) measurement in HVAC applications.
The use of the EE160 in any other way than described in this manual bears a safety risk for people
and the entire measurement installation and is therefore not allowed. The manufacturer cannot be
hold responsible for damages as a result of incorrect handling, installation, and maintenance of the
equipment.
Please note:
For accurate measurement it is essential that the temperature of the sensing probe and mainly of the
sensing head is same as the temperature of the air to measure. Avoid mounting the EE160 sensor in a
way which creates temperature gradients along the probe.
In order to avoid damage to the instrument or health hazards, the measuring equipment must never be
manipulated with tools that are not specifically described in this manual.
The sensor may only be utilized in accordance with the conditions defined in the technical data.
Otherwise, measurement inaccuracies will occur and equipment failures cannot be ruled out.
