Abschluss der Inbetriebnahme
1. Falls sich die Kommunikationszentrale im Adressiermodus
befindet (Programmier-LED leuchtet), muss sie in den Nor-
malmodus umgeschaltet werden.
2. Um das korrekte Absetzen der Meldungen sicher zu stellen,
muss der Meldungsschalter S2 in die Stellung
werden.
3. Die Verbindung über Modem zur Leitstelle muss nach er-
folgter Inbetriebnahme unbedingt kontrolliert werden, um
unnötige Servicegänge aufgrund nicht funktionierender Mo-
demkommunikation zu verhindern.
Dazu muss vor dem Kommunikationsaufbau der RS-232-
Schalter S1 in die Stellung
das Modem mit der Kommunikationszentrale verbunden
ist, kann der Modemreset-Taster während 6 Sekunden ge-
drückt werden.
Fehler beim Kommunikationsaufbau werden an der roten
Störungs-LED angezeigt (blinkt).
4. Klemmenabdeckung auf der Kleinspannungsseite montieren.
(Schluss-)Kontrolle vor Ort
1. Leuchtet die grüne Betriebs-LED?
2. Sind die beiden roten LED (Störungs-LED und Program-
mier-LED) dunkel?
3. Ist der RS-232-Schalter S1 in Stellung
4. Ist der Meldungsschalter S2 in Stellung

Installation
Place of installation
• In a dry room
• Mounting choices:
− In a compact station
−
In a control panel (front, inner wall, or on a wall mounting
rail)
− On a control panel front
−
In the sloping front of a control desk
• Permissible ambient temperature: 0...50 °C
• Ensure that the unit is easily accessible for service staff
Electrical installation
• Ensure that the local regulations for electrical installations are
complied with
• Electrical isolation of the central communication unit from
AC 230 V mains supply must be ensured by a labeled and eas-
ily accessible fuse with a release current of 10 / 16 A
• Only devices with potential-free contact outputs may be con-
nected to the fault inputs
• Permissible cable lengths:
− Konnex bus: Refer to the following pieces of documentation:
Data Sheet N3127, Konnex bus
Basic Documentation P3127, System engineering
−
RS-232: Maximum 15 m

Wall mounting
1. Hold unit against the wall and mark fixing holes.
2. Drill holes in the wall.
3. Screw unit to the wall.
Refer to Figure
Notes on wall mounting:
For wall mounting with screws, there are 4 fixing holes
available.
The base has raised mounting surfaces.
Screws: Maximum diameter 3.5 mm
For drilling template, refer to Dimensions on page 29
Mounting on a wall mounting rail
1. Fit the rail.
2. Mount unit on the rail.
3. If required, secure unit (depending on the type of mounting
rail).
Refer to Figure
Note on rail mounting:
The base has a snap-on facility for wall mounting rails (type
EN 50 022-35×7.5) and can be removed with a screwdriver.
Wiring
1. Permitted per terminal are solid wires or stranded
wires (twisted or with ferrules)
• 1 core: 0.5 mm
• 2 cores: 0.5 mm
• 3 cores: not permitted
Terminal 15 may not be used
Refer to Figure
2. Wire up the connection terminals:
Top: Low-voltage
Bottom: Mains voltage
Refer to Connection diagram on page 28
N1 Central communication unit OZW771...
N2 Konnex device (maximum number of devices depends
on the type of OZW771...)
P1,P2 Devices with potential-free contact output for signaling
faults
3. Strain relief for the cables connected to terminals N
and L (AC 230 V) is mandatory:
Refer to Figure
4. Secure cables to the base of the unit with the help of
cable ties.
Terminal covers
• If there is no protection against electric shock hazard
(e.g. in heating rooms, false ceilings or false floors):
Always use terminal covers
• Single-insulated cables connected to terminals N and
L (AC 230 V) must be used with insulating sheathing:
Refer to Figure
• Make certain that the terminal cover on the mains volt-
age side is secured with the 2 cable ties provided:
Refer to Figure
• If protection against electric shock hazard is ensured
(e.g. in control panels or cabinets), mounting without
terminal covers is permitted
