Equipment is protected
throughout by DOUBLE
INSULATION.
ENDA EDT1323 is intended for installation in control panels. Make sure that the device is used
only for intended purpose.
During an installation, all of
the cables that are connected to the device must be free of electrical power. The device must be
protected against inadmissible humidity, vibrations, severe soiling and make sure that the operation
temperature is not exceeded. The cables should not be close to the power cables or components.
The electrical connections must be carried out by a qualified staff
and must be according to the relevant locally applicable regulations.
NOTE :
SENSOR INPUT:
Pay attention to the colors of the PTC probe cables while
connecting them to the PTC SENSOR input of the device.
1) Mains supply cords shall meet the requirements of
IEC 60227 or IEC 60245.
2) In accordance with the safety regulations, the power
supply switch shall bring the identification of the
relevant instrument and it should be easily
accessible by the operator.
Note :
For removing mounting clamps:
Push out the flush-mounting
clamp in direction 1as shown
in the figure below. Then, pull
out the clamp in direction 2.
Note :
1) Panel thickness
should be maximum
7 mm.
2) If there is no 60mm
free space at the back
side of the device, it
would be difficult to
remove it from the
panel.
