HARDWARE DESCRIPTION
CAUTION
The SMOR contains electronic components that could be damaged by electrostatic discharge if
those currents flow through certain terminals of the components. The main source of electrostatic
discharge currents is the human body, especially in conditions of low humidity, carpeted floors and
isolating shoes. Where these conditions exist, care should be exercised when removing and
handling the modules. The persons handling the modules should make sure that their body charge
has been discharged, by touching some surface at ground potential before touching any of the
components on the modules.
5.1. PHYSICAL DESCRIPTION
5.1.1. CASE
The SMOR's case is made from stainless steel and consists of the main body and a covering lid. The main
body of the case contains the blocks of terminals necessary to carry out the external connections and guides
to support the trays which contain the internal parts of the relay. The trays can be pulled out in order to
facilitate the maintenance and servicing of the relay.
5.1.2. ELECTRICAL CONNECTIONS
All the electrical connections for voltage, current, digital input and output relays are made using the blocks of
terminals fixed to the rear part of the case. The connections required for the unit's communications are made
using three DB-9 type connectors, one on the front and two on the rear when using communication option
RS-232. One of these connectors is replaced by the corresponding fiber-optic connector in the models which
include this option.
5.1.3. INTERNAL CONSTRUCTION
Internally the SMOR unit is divided into 2 trays and a case. The case consists of the case with the blocks of
terminals described above. Inside the lower tray are located the CT and VT which are connected to the CPU
by a frontal bus.
The lower tray carries the magnetic module and a printed circuit board which contains the power supply, the
digital inputs and also the trip outputs and auxiliary outputs on the basic version (model without expansion
board).
The upper tray carries the board with the protection system CPU and the board with the communications.
This tray can also carry as an option the input and output expansion board.
The front panel consists of a covered keyboard and a board which carries the alphanumeric display, the
LEDs and the Reset button. The model number (see list of models in Chapter 4) and the technical
characteristics of the unit are situated on the front panel of the relay.
The 16 indicator LEDs can be identified using labels which can be placed beside them.
A frontal bus is responsible for the connections between the boards described above. Both trays can be
pulled out. To do so you first have to release the front panel which is fixed to the case with two screws and
pull it out, removing the flat cable which connects it to the CPU. It is then possible to remove the frontal bus.
