Wiring Diagram - Nice Mindy A500 Instrucciones Y Advertencias Para El Instalador

2.1) Input voltage selection:
The power unit can either work with three-phase or single-phase power supply (see wiring diagrams) with voltages of
400V or 230V. Select the input voltage by fitting in a jumper between the "COM" terminal and the "230" terminal or the
"400" terminal as shown in figure.

2.2) Wiring diagram:

Under no circumstances, while wiring or plugging in the various
cards, may the unit be electrically powered, to safeguard the
operator and avoid damaging the components.
Please also bear in mind that if the inputs of the NC (Normally Closed)
contacts are not used they should be jumpered with the "common"
terminal; if there is more than one contact, then they should be
connected in SERIES. If the inputs of the NO (Normally Open)
contacts are not used they should be left free and if there is more
than one contact then they should be connected in PARALLEL. The
contacts must be of the mechanical type and potential-free; no
connections are allowed, such as those defined as "PNP", "NPN",
"Open Collector" etc..

N.B.:
Only qualified and expert personnel may carry out installation and subsequent maintenance operations following the rules of good workmanship and
in compliance with EEC directive 89/392 (Machine Directive) and, in particular, EN 60204 (Electrical wiring of machines).

Before making connections, check that the selection corresponds to
the available input voltage.
Any errors during the selection can seriously damage the
components of the control unit!
The drawing in figure shows the connections of the control unit with
three-phase 400V power supply.
To connect the control unit with 230 Volt single-phase or three-phase
power inputs, please refer to the drawings in figure 3a-3b.
