• Choose an installation site that is strong enough
to sustain the weight of the device, also bearing
in mind particular environmental aspects, such as
exposure to strong winds.
• We strongly recommend using only approved
brackets and accessories during installation.
• Installation category (also called Overvoltage
Category) species the level of mains voltage
surges that the equipment will be subjected to.
The category depends upon the location of the
equipment, and on any surge voltage protection
provided. Equipment in an industrial environment,
directly connected to major feeders/short branch
circuits, is subjected to Installation Category
III. If this is the case, a reduction to Installation
Category II is required. This can be achieved by
use of an insulating transformer with an earthed
screen between primary and secondary windings,
or by tting UL listed Surge Protective Devices
(SPDs) from live to neutral and from neutral to
earth. Listed SPDs shall be designed for repeated
limiting of transient voltage surges and the
following rated operation conditions: Type 2 (SPDs
permanently connected to the power network and
intended for installation on the load side of the
service equipment); Nominal Discharge Current
(In) 20kA min. For example: FERRAZ SHAWMUT,
STT2240SPG-CN, STT2BL240SPG-CN rated
120Vac/240Vac, (In=20kA). Maximum distance
between installation and reduction is 5m.

• Accertarsi di installare i dispositivi in maniera
tale da garantire la sicurezza dell’impianto e del
personale addetto all’installazione.
• Scegliere la postazione di installazione in modo
che sia sucientemente solida da sostenere il
peso del dispositivo, considerando anche aspetti
ambientali particolari come esposizione a vento
forte.
• Si raccomanda di utilizzare solo stae o accessori
consigliate per l’installazione.
• La categoria di installazione (detta anche categoria
di sovratensione) specica i livelli della tensione
transitoria di rete alla quale l’apparato è soggetto.
La categoria dipende dal luogo di installazione
e dalla presenza di dispositivi di protezione
contro le sovratensioni. Un dispositivo per
ambienti industriali, connesso ai rami principali
dell’impianto di alimentazione è soggetto alla
categoria di installazione III. Se questo è il caso, è
richiesta una riduzione alla categoria II. Ciò può
essere ottenuto utilizzando un trasformatore
di isolamento con schermatura connessa a
terra tra il primario ed il secondario, o tramite
l’impiego di dispositivi di protezione contro le
sovratensioni (SPD), UL listed, connessi tra la fase
ed il neutro e tra il neutro e terra. I dispositivi SPD
UL listed, dovranno essere predisposti per limitare
sovratensioni transitorie in modo ripetitivo e per
le seguenti condizioni nominali di funzionamento:
Tipo 2 (Dispositivi SPD connessi permanentemente
alla rete di alimentazione, per installazioni dal lato
del carico del dispositivo di servizio); Corrente
nominale di scarica (In) 20kA minimi. Si possono
utilizzare ad esempio: FERRAZ SHAWMUT,
ST23401PG-CN, ST240SPG-CN specicati per
120Vac/240Vac, (In=20kA). La distanza massima tra
l'installazione e la riduzione è di 5m.
