Type using compression terminals
5.1.1
1/1 size case
(i)
Figure 5.1-2 shows diagrams of the 1/1 size case constructed with type using compression
terminals: (a) IED internal structure seen from the front, (b) Terminal block arrangement seen
from the rear, and (c) schematic diagram.
Viewing from the front side (Figure 5.1-2.a)
Slots are provided for mounting modules. A transformer module (VCT), a signal processing and
communication module (CPU), and a power supply module (PWS) are mounted at predefined
locations in the case. Binary IO modules (BI, BO, and BIO) are placed in slots (IO#1 to IO#8),
these slot locations are determined before factory shipment. For detailed information on slot
locations, module types and their connections for all IEDs, see external connection figures.

Viewing from the rear side (Figure 5.1-2.b)
The group of terminal blocks viewed from the rear is shown. With respect to BIs, BOs, and
BIOs, their terminal blocks are designed with upper terminal and lower one and they are
labeled with alpha-numeric reference "T1", "T2" and so on. The upper and lower terminals are
provided in the form of one terminal block for respective BIs, BOs, or BIOs. Terminal screw
numbers for each terminal block relate to individual binary circuits. The user should check
respective configuration circuit (see section 5.4 or later). Each slot for the BIOs is identified
with its alpha-numeric reference (or slot reference) on an IED case. For example, the user can
identify that slot "IO#1" is linked with alpha-numeric reference "T1".
PWS terminal block is placed on the far left side; hence, the user finds it with alpha-
numeric reference "T9", and that is discussed later (see section 5.5).
Communication modules, which are placed between VCT and BIOs, are labeled with "C11"
to "C15". Those are provided for LAN, IEC61850 communication, etc.
Schematic figure (Figure 5.1-2.c)
A schematic figure illustrates the location of slots and terminals: VCT, BIOs, and PWS. It is
useful when the user need to set BIO modules using their setting tables (see section 5.4).
