CONNECTION DIAGRAM

ENDAEPA242 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 electrical power. The device must be protected against
inadmissible humidity, vibrations and severe soiling. Make sure that the operation temperature isnot exceeded. The cables should not
be close to the power cables or components.

CAUTION :
If 5A / CT20-30 and 60mV inputs are connected at the same time, the measurement will be incorrect.

Note 1 : Coil and Discrete input parameters are not available in the devices those have no relay
Note 2 : menu parameters can be used as “Holding Register” or “Coil.0tyP
Note 3 : Value read in 0th address of input register gives the measured value. Also, the 1st address of the input register

specifies the decimal part of the measured current value.
For example ;
Value read in 0th address of input register is 2842, if value read in 1st address from input register as 1, it is 284.2
Value read in 0th address of input register is 2842, if value read in 1st address from input register as 2, it is 28.42
Value read in 0th address of input register is 2842, if value read in 1st address from input register as 3, it is 2.842
