ASSEMBLY INSTRUCTIONS
SINUS PENTA
MODULAR INVERTERS
10/
47
NOTE
Power supply unit 3 is available for size S80 only.
NOTE
The power supply units (1, 2 and 3 if required) may also be mounted as the
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.
