Removing the bus terminal (Figure 3)
-
The bus terminal is located on the top of the N 525E
(D1)
-
The bus terminal (D2) consists of two sections (D2.1,
D2.2), each with four terminal contacts. Care should
be taken not to damage the two test sockets (D2.3),
either by accidentally connecting them to the bus
conductor or with the screwdriver (when trying to
remove the bus terminal).
-
Carefully insert the screwdriver in the wire entry slot
underneath the bus terminal (D2) and pull the bus
terminal forwards out of the N 525E (D1).
Note:
Care should be taken as there is a risk of shorting
the device!
Connecting the bus terminal (Figure 3)
-
Place the bus terminal in the guide slot and press the
bus terminal (D2) backwards until it reaches the stop.
Connecting the bus cable (Figure 3)
-
The bus terminal (D2) is suitable for single-core
conductors with 0.6... 0.8 mm Ø.
-
Strip approx. 5 mm of insulation from the conductor
(D2.4) and plug in the terminal (D2) (red=+, black=-).
Disconnecting the bus cable (Figure 3)
-
Remove the bus terminal (D2) and the conductor
(D2.4) out of the bus cable by rotating it backwards
and forwards.

Connecting mains voltage and DALI bus cables
-
The connections are designed with plug-in technology.
-
Strip approx. 10-11 mm of insulation from the conduc-
tors and slide in the respective terminal.
Cross-sections:
•
The following conductor cross-sections are permitted:
-
0.5 ... 3.3 mm2 (AWG 12) single-core
-
0.5 ... 3.3 mm2 (AWG 12) stranded multi-core
-
0.5 ... 3.3 mm² (AWG 12) finely stranded, untreated
-
0.5 ... 1.5 mm2 finely stranded, with connector
sleeve
•
The mains connection must be fused with a circuit-
breaker of characteristic B or C with a max. nominal
current of 6 A!
Mounting the insulating cap
-
If the device should be mounted on a DIN rail without
a data rail, the contact system must be covered with
the supplied insulating cap.
Removing the locating clamp
(Figure 4)
-
The locating clamp (E3) encloses the contact system
(E2) on the rear of the DIN rail mounted device (E1).
-
Insert the screwdriver between the DIN rail mounted
device (E1) and the locating clamp (E3) and remove
the clamp.
Clipping on the insulating cap: (Figure 4)
-
Place the insulating cap (E4) on the contact system and
press so that it snaps in place.
