Safety instructions

General Safety Instructions
•
Excessive mechanical loads and incorrect usage should always be avoided.
•
Take care when unscrewing the filter cap as the sensor element could be damaged.
•
The sensor is an Electro Static Discharge sensitive component (ESD). When touching the sensor
element, ESD protective measures should be followed.
•
Grip sensors only at the lead wires.
•
Installation, electrical connection, maintenance and commissioning should be performed by qualified personnel only.
•
The devices are constructed for the operation of separated extra-low voltage (SELV).
Safety instructions for use of the alarm module with voltages >50V
•
To insulate the optional alarm module from the low-voltage side of the transmitter, the
partition provided for this purpose must be fitted in the lower section.
•
During operation of the instrument the modular housing must be completely closed.
•
The protection class of an opened housing corresponds to IP00 and direct contact
with components carrying dangerous voltages is therefore possible. In general, work on live components
should be avoided and when absolutely necessary, should be performed by qualified personnel only.
Safety instructions for use of the integrated power supply (option V01)
•
During operation of the instrument the modular housing must be completely closed.
•
The protection class of an opened housing corresponds to IP00. In general, work on live components
should be avoided and when absolutely necessary, should be performed by qualified personnel only.
1.3 Environmental aspects
Equipment from E+E Elektronik
When you dispose the equipment you should avoid environmental pollution.
For disposal of the transmitter the individual components must be sorted with care. The
housing consists of recyclable polycarbonate or metal (aluminium, Al Si 9 Cu 3). The electronics must be
collected as electronic scrap and disposed of according to the regulations in force.

PRODUCT DESCRIPTION

Humidity/temperature transmitters of the EE31 series provide multifunctionality, highest accuracy and simple
installation and maintainance. The modular housing enables a user-friendly operation and a fast replacement
of the sensor unit for service purposes.By selecting a suitable housing version the EE31 series can be used
for the entire range of humidity measurement applications:
•
Model A for wall mounting.
•
Model B for duct mounting.
•
Model D, model H with remote sensing probe
•
Model E with remote sensing probe for pressure-tight applications up to 20bar
•
Model F for wall mounting with rear cable outlet.
