1. OVERVIEW
High power inverters of the SINUS PENTA series manufactured from Elettronica Santerno are obtained by
matching the following individual modules:
-The Control Unit, containing the control board and the interface board (ES842);
-The Power Supply Module, composed of a three-phase power rectifier and its control circuit and
supply circuits;
-The Inverter Module, composed of one inverter phase and its control circuits;
-The braking unit (optional)
Four types of Inverter Modules are available:
- Basic Inverter Module;
- Inverter Module with on-board control unit;
- Inverter Module with on-board aux supply unit (to be used for those models which are not equipped
with the power supply module –size S74);
- Inverter Module with on-board splitter unit (to be used for the models allowing connection in parallel
of the inverter modules).
Two types of braking unit (optional) are available:
-Basic version;
-Version provided with on-board splitter unit (to be used for the models allowing using two parallel-
connected braking units). See section 2.5 for the internal wiring.
The inverter properly dimensioned to meet the requirements of your industrial application is obtained by
composing the components above.
This manual covers the assembly instructions of the modular SINUS PENTA inverters S74-S80 and is
addressed to the Customers who have not purchased the Sinus Penta CABINET version.
NOTE
As per the greatest sizes (S84-S90), the existing configurations only are covered in
this manual; for details on the inverter assembly, please contact Elettronica
Santerno.
The inverter assembly comprises the wiring between the inverter module and the power supply units, if fitted.
This Manual also covers the recommended input/output reactors.
NOTE
This Manual is a complement to the Sinus Penta’s Installation Instructions.
CAUTION
Properly configure ES842 control board inside the control unit case. When
ordering the inverter, always state the inverter configuration you intend to obtain.

2. WIRING DIAGRAM FOR MODULAR INVERTERS S74–S80
NOTE
In the modular inverters wiring diagrams, the power supply units are defined as
illustrated in the diagram below:
Figure 1: Cascade connection of the power supply modules
Based on the inverter size, the Power Supply Unit 2 may be either the last unit in the chain (LAST in Size S75)
or the middle unit in the chain (MIDDLE in Sizes S80-S90).
Therefore, different settings are required for ES840/1 board, as described in section 2.6.1 later on in this
manual.

two (three) central power supply units, between inverters modules U1/V1/W1
and U2/V2/W2.
NOTE
The braking units are optional.
NOTE
The internal wiring for the dual configuration of the braking units is given in
section 2.5.
CAUTION
In case of fuse line protection, always install the fuse failure detection device,
that disables the inverter, to avoid single-phase operation of the equipment.
NOTE
Details on the reactors are given in Three-phase Input Reactors for Modular
Inverters S75 and S80 and Single-phase Output Reactors for Modular
Inverters S75 and S80.
CAUTION
As shown in the figure above, use wires with the same length for each of the
two parallel-connected inverters to obtain separate links reaching the
connected motor. Three-phase wires are recommended.
