The design of the front plate is the same for all 4 models (refer
to Fig. 4) whereby, the connection terminals of the EPT202 for
control panel mounting and 19" subrack assembly are at the
rear. The SPI-Bus connection is located internally.
The menus, measured values and parameters are indicated on
the 8-line LCD display.
The 5 operator keys can be used to switch between the
individual menus, change parameters and reset measured
values.
With a suitable cable, the device can be connected via the
sub D plug to a PC for parameterization or for data
transmission.
The SPI bus on the side can be used to connect extra modules
such as the CT with 2 extra CT inputs.

• Green POWER LED on: Device is running.
Green POWER LED flashing: Key lock released.
• Yellow ALARM LED on: ALARM contact is tripped.
• Red TRIP LED on: TRIP contact is tripped.
• Red ERROR LED on: Device error
