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.

If you hold down the keys for 0.6 seconds while changing the parameters you skip to fast change mode. If you hold down the
keys more than 5 seconds the active parameter would change faster.
If you wait 25 seconds before holding down the keys or power off and power up again, you skip to operation mode.
If current transforming rate is lower than 10, measuring value can be displayed like (0.00) or (0.0).
If current transforming rate is between 10 and 100 ,measuring value can be displayed like (0.0) or
(0).
If current transforming rate is higher than 100, measuring value can be displayed like only (0).
