Important note:
Manual operation is for emergency operation only and not af-
fecting the application program. No telegram is sent on the
bus, and the new switching status is unknown to the soft-
ware.
At bus voltage failure / recovery a previously manually oper-
ated relay will also be set automatically to the configured po-
sition.
Installation Instructions
The device may be used for permanent interior installations
in dry locations within distribution boards or small casings
with DIN rail EN 60715-TH35-7,5.
This equipment is intended for field installation within the
enclosure of another product.

Mounting
General description
The N-system DIN-rail device can be installed in the
instabus EIB lighting control panel, surface or flush mounted,
or to any DIN rail in distribution boards, surface or flush
mounted,complying with EN 60715-TH35-7,5 that has a da-
ta rail installed.
The connection to the bus line is established by clicking the
device onto the DIN-rail (with a data rail installed). Take care
that the type plates of all devices on a DIN-rail can be read in
the same direction, guaranteeing the devices are polarised
correctly.
Mounting the Power Supply unit N 125 to a DIN-rail
• Slide the DIN-rail device (B1) onto the DIN-rail (B2) and
• swivel back the DIN-rail device until the slide clicks into
place audibly.
Dismounting DIN-rail devices
• Remove all connected wires,
• press down the slide (C3) with a screw-driver and
• swivel the DIN-rail device (C1) from the DIN-rail (C2).
Connection to the bus without data rail
If the connection is established via bus connection block
(data rail not installed) the data rail connection system has to
be covered with the enclosed insulation hood after removing
the guiding hood e.g. with a screw driver to guarantee a suf-
ficient insulation from the DIN rail.
Removing the guiding top
-
The guiding top (D3) surrounds the contact system (D2)
on the back side of the device (D1).
-
Insert the screw driver between the DIN-rail device (D1)
and the guiding hood (D3) and remove the guiding hood.
Inserting the insulation top
-
Put the insulation top (D4) onto the contact system and
click it into place by a slight pressure.
Wiring
Connecting mains
• Mains is connected via screwless plug-in terminals (D1).
• Remove approx. 3/8" (9,5mm) of insulation from the wire
(D1.1) and plug it into the terminal (D1).
Disconnect mains
• Press the terminal lock (E1.2) with a screw-driver and
• remove the wire (E1.1) from the terminal (E1).

Slipping on of the safety extra low voltage block
-
slip the connection block onto the guide slot and
-
press the connection block down to the stop
Connecting the safety extra low voltage block
-
The connection block (E1) can be used with single core
conductors Ø 0,6 ... 0,8 mm.
-
Remove approx. 5 mm of insulation from the conductor
(E2) and plug it into the connection block (E1) (red = +,
black = -).
Disconnecting the safety extra low voltage block
-
Unplug the connection block (E1) and remove the bus ca-
ble conductor (E2) while simultaneously wiggling it.
