1. OVERVIEW
The drives of the SINUS PENTA series, sizes S41, S42, S51 and S52 may be parallel connected to make up
a system composed of maximum N. 3 units. Special additional components are required.
The units making up the parallel connections are called the Master (N.1 drive) and Slave(s) (N.1 or 2 drives)
throughout this manual.
This manual covers how to assemble parallel connected drives of the SINUS PENTA series, sizes S41, S42,
S51 and S52 as well as their additional components (wiring cables, current split inductors).
Assembly consists of wiring the drives and the relevant components to obtain the drive parallel connection.
NOTE
This manual is an addition to the SINUS PENTA –Installation Guide.
The sizes that can be obtained by parallel-connecting Sinus Penta drives S41, S51, S42, S52 are given in
Table 1 and Table 2.

Master drive this is drive housing the control board and it is always installed on the left-hand side of the
slave drives.
First Slave drive this is the slave installed in the middle position when there are N.3 parallel-connected
drives.

Figure 3 shows an example of a parallel-connection of N.3 inverters installed inside a cabinet. Do the
following:
1. Do not exceed maximum clearance between the drives
2. Make sure that the path of the flat cable for the control signals is clear; in particular, the flat cable must
not touch live parts and must not be laid close to dangerously live parts. It must not be close to
electromagnetic disturbance or to parts that may mechanically damage it; it must not touch or be close
to parts that may reach 60°C or more. Arrange a clear area of approx. 200mm next to the path of the
flat cable and centred on the flat cable itself.
NOTE
Dimensions, weights and fixing points of each drive are given in the SINUS

CAUTION
Always install the fuse failure detection device, that disables the inverter, to
avoid single-phase operation of the equipment.
NOTE
If the application does not require any device connected to the DC bus (e.g.
a braking unit) or 12-pulse power supply, it is not necessary to connect to
each other the DC bus terminals of the drive.

4.1. Components, Wiring and Sizes of the Protective Devices
The components required for the parallel connection of the Sinus Penta drives are given in the tables below.
The minimum requirements of the inverter cables and the protective devices needed to protect the system
against short-circuits are also given in the tables below. It is however recommended that the applicable
regulations in force be observed; also, check if voltage drops occur for cable links longer than 100m.
For the largest inverter sizes, special links with multiple conductors are provided for each phase. For
example, 2x150 in the column relating to the cable cross-section means that two 150mm2parallel conductors
are required for each phase.
Multiple conductors shall have the same length and must run parallel to each other, thus ensuring even
current delivery at any frequency value. Paths having the same length but a different shape deliver uneven
current at high frequency.
Also, do not exceed the tightening torque for the terminals to the bar connections. For connections to bars,
the tightening torque relates to the bolt tightening the cable lug to the copper bar. The cross-section values
given in the tables below apply to copper cables.
The links between the motor and the SINUS PENTA drive must have the same lengths and must follow the
same paths. Use 3-phase cables where possible:
1. N.1 safety device on the supply mains to the parallel-connected drives.
2. N.1 safety device on the supply mains to each drive that is parallel-connected to the other drives.
3. N.1 input inductor to the supply mains to each drive that is parallel-connected to the other drives. The
inductor is utilized to split the supply current.
4. N.1 output inductor between each parallel-connected drive and the motor. The inductor is utilized to split
output current.
The parallel connection of the motor cables is to be done directly to the motor terminals as shown in Figure
4, in order to get even better current splitting.
NOTE
The notes below are general-purpose guidelines that cannot be applied to
any configuration. The component dimensioning shall meet the
environmental requirements as well as the requirements of the place where
the equipment is installed.
