Case and module slots in MainUnit and SubUnits
The case structures for MainUnit and SubUnit are shown in (a) Internal structure (front view),
(b) Terminal block arrangement (rear view), and (c) schematic diagram. If the IED—except the
stand-alone type—is ordered, the arrangement of the communication ports is different between
the 'Max. Dual Ports' of MainUnit and the 'Dual Ports with LAN for Local PC'.
Viewing from the front side (Figure 4.1-2.a and others)
(i)
Thirteen slots are provided for mounting modules. The transformer module (VCT), the signal
processing and communication module (CPU/PCX), and the power supply module (PWS) are
mounted at predefined locations in the case. The binary IO modules (BIOs) are placed in slots
(IO#1 to IO#8), these slot locations are determined before factory shipment. For slot locations,
module types and their connections etc., see
Viewing from the rear side (Figure 4.1-2.b and others)
(ii)
The group of terminal blocks viewed from the rear is shown. With respect to BIO, the terminal
blocks are designed with both upper and lower terminals; they are labeled with alpha-numeric
reference "T1", "T2" and so on. Both the upper and lower ones are provided in the form of a
single terminal block for respective BIOs. The terminal screw numbers for each terminal block
relate to the individual circuits. The user should check the configuration for each circuit. (For
details, see section 4.4 or later). Each slot is identified by its alpha-numeric reference (or slot
reference) on the case. For example, the user can identify that slot "IO#1" is linked with alpha-
numeric reference "T1".
For PWS, note that the terminal blocks are placed on the left hand side. The user can also find
alpha-numeric reference "T9" for PWS (for details, see section 4.5 or later)
When the stand-alone type of MainUnit is ordered, communication ports are labeled "C11" to
"C15", and Note an optical transceiver module (OPT2) is not included in the MainUnit.
When the Dual Ports with LAN for Local PC of MainUnit is ordered, the communication ports
are labeled "C11" to "C25". Ports at C11 and C12 are used IEC61850 communication, whereas
the one at C13 is provided for Local PC engineering. The OPT2 is mounted at C21 and C22.
The OPT2 is mounted at C13 and C14 when the Max. Dual Ports is selected. It also mounted
at C13 in the SubUnit.

(iii)
The slots and terminal blocks are shown. Find the location of VCT, BIO, and PWS, etc. It is
useful when the user has to set BIOs using the setting tables (see section 4.4)
