Dimensions
Note :
1)
2)
While panel mounting, additional distance
required for connection cables should be
considered.
Panel thickness should be maximum 10mm.
3) If there is no 90mm free space at the back side
of the device, it would be difficult to remove it from
the panel.
For removing mounting clamps:
- Push out the flush-mounting clamp
In direction 1 shown in figure below.
- Pull out the clamp in direction 2

Connection Diagram
ENDA EPA741 is intended for installation in control panels.Make sure that the device is
used only for intended purpose.The electrical connections must be carried on by a
qualified staff and must be according to the relevant locally applicable regulations.
During an installation, all of the cables that are connected to the device must be free of
energy. 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.
