5. Carefully turn the two IEDs up-side down.
6. Fasten the second side-by-side mounting plate.
Use the remaining four screws.
7. Carefully fasten the mounting angles (4) to the sides of the IED.
Use the fixing screws available in the mounting kit.
8. Insert the IED into the cut-out.

5.4 Making the electrical connection
5.4.1 IED connectors
5.4.1.1 Overview
The quantity and designation of connectors depend upon the type and size of the
IED. The rear cover plates are prepared with space for the maximum of HW
options for each case size and the cut-outs that are not in use are covered with a
plate from factory.
Overview
Table 1: Basic modules
Module Description
Combined backplane module (CBM) A backplane PCB that carries all internal signals
between modules in an IED. Only the TRM (when
included) is not connected directly to this board.
Universal backplane module (UBM) A backplane PCB that forms part of the IED
backplane with connectors for TRM (when
included), ADM etc.
Power supply module (PSM) Including a regulated DC/DC converter that
supplies auxiliary voltage to all static circuits.
An internal fail alarm output is available.
Numerical module (NUM) Module for overall application control. All
information is processed or passed through this
module, such as configuration, settings and
communication.
Local Human machine interface (LHMI) The module consists of LED:s, an LCD, a push
button keyboard and an ethernet connector used
to connect a PC to the IED.
Transformer input module (TRM) Transformer module that galvanically separates
