INSTALLAZIONE
Installare l’apparecchio secondo gli schemi
di connessione riportati a pag. 18-19.
Per inserzione trifase il T.A. deve essere
connesso sulla fase non
utilizzata per
alimentare l’apparecchio, come indicato
negli schemi di connessione a pag. 18-19.
L’apparecchio viene fornito predisposto
per il riconoscimento del senso della
corrente del T.A.. In caso di impianti di
cogenerazione è necessario disabilitare
questa funzione (vedere capitolo menù
avanzato) e provvedere alla corretta
connessione del T.A..
Il secondario del T.A. deve essere
collegato a terra.
WARNING!
This equipment must be installed by
qualified personnel, in compliance with
regulations in force for electrical systems, to
avoid damages or safety hazards.
The pfoducts, illustrated in this document,
are subject to be revised or improved at any
moment. Technical data and descriptions do
not therefore have any contractual value.

controller
3 digit 7 segment LED display
4 key membrane keypad
TTL-RS232 serial interface for set-up and
automatic testing via PC (Personal
Computer)
Internal temperature sensor
Advanced functions for capacitor current
overload measurement, average weekly

INSTALLATION
Install the controller according to wiring
diagrams given on page 18-19.
For three-phase connection, the CT
(Current Transformer) must be connected
to the free phase, i.e. not
on phases used
to supply the unit, as indicated in the
wiring diagrams on page 18-19.
The controller automatically recognizes
the CT current flow. In case of
co-generation systems, disable this
function (refer to advanced menu section)
and connect the CT correctly.
The CT secondary must be
earthed/grounded.

WERSJE
DCRK5 5 stopni, obudowa 96x96mm
DCRK7 7 stopni, obudowa 96x96mm
DCRK8 8 stopni, obudowa 144x144mm
DCRK12 12 stopni, obudowa 144x144mm
INSTALACJA
Należy podłączyć regulator zgodnie ze
schematem podanym na stronie 18 i 19.
W układzie trójfazowym przekładnik prądowy
musi być podłączony do wolnej fazy, to jest tej,
która nie jest używana do zasilania
urządzenia, jak pokazano na schemacie
podanym na stronie 18 i 19.
Regulator automatycznie rozpoznaje przepływ
prądu przez przekładnik. W układach
kogeneracji należy wyłączyć tą funkcję
(zobacz menu zaawansowane) i podłączyć
przekładnik we właściwy sposób.
Uzwojenie wtórne przekładnika koniecznie
musi być uziemione.
