Per evitare scintille, non collegare o scollegare
l'apparecchiatura prima di avere tolto tensione di ingresso e
prima che sia avvenuta la scarica dei condensatoriinterni (min.
1 minuto).
RISQUE DE BRULURES, EXPLOSION, INCENDIE,
ELECTROCUTION, DOMMAGE AUX PERSONNES.
Ne jamais effectuerdes opérations sur les parties sous
tension! Danger de mort! Le récipient peut produire des
brulures, le laisser refroidir avant de toucher l'appareil. Ne
faites pas pénétrerdes liquides ou des corpsétrangers dans
l'appareil. Pour éviter des étincelles, ne pas connecter ou
déconnecter l'équipement jusqu'àce que vous avez supprimé
la tension d'entrée et avant qu'elle n'ait lieu de décharge des
condensateurs internes (minimum 1 minute).

USER INSTRUCTIONS
1) Description: DIN rail Universal Active Oring Controller for redundant connection to a common Load of 2 DC Power supplies ofsame rating, with any voltage in the range
12…85Vdc and Load Current ≤ 20A.
Warning: voltages ≥ 60Vdc are dangerous! Use appropriate safety rules!
2) Installation: use DIN-rails according to EN 60715. Installation should bemade vertically(see Fig.4). For better device stability fix the rail to the wallclose to the point where
the device is to be mounted. In order to guarantee sufficient convection, we recommend observing a minimumdistance to other modules (see Fig.3).
3) Connections: the device is equipped with pluggable screw terminals. To avoid sparks, do not connect or disconnect the connectors before having previously turned-off input
power and waited for internal capacitorsdischarge (minimum 1 minute)
In order to complywith UL certification, use appropriate copper cablesof indicated crosssection, designed for an operating temperatures of:
60°C for ambient up to 45°C
75°C for ambient up to 60°C
90°C for ambient up to 70°C
Strip the connecting ends of the wiresaccording to the indication andensure that allstrands of a stranded wire enter the terminal connection (see Fig.5)
4) Input/Output connection: The device is suitable for SELV and PELV circuitry (if you usea source that having Uout higher60Vdc is not a SELV device)
Check Uout before connecting thepower supply to the load.
5) Operating: at the OR20 ispossible connect 2 DC Power suppliesin order to obtain a redundancyconnection system (see Fig.7), the 2 Power supplies must have setted the
same Output voltage rating in order to ensure the corrected redundancy. The correctly current sharing is possible verifythrough the status LEDs “IN1 OK” and “IN2 OK”(see
Fig.1), when you connect 2 DC Power supplies, what is has the higher output voltage determines the voltage threshold and turnson the respective LED, in order to ensure the
correct current sharing now you must increase Output voltage of the other Power supply until the two LEDs will not be turned on simultaneously. The precision of redundancy
which allows the simultaneous lighting of the two LEDs is about 10% of the highest voltage threshold. When the two LEDs are simultaneously turned on is ensured the
redundancy and also the Diagnostic Output "OR OK" relay it is closed.
