Removing the bus terminal (Figure 3)
The bus terminal is located on the top of the roller
-
shutter switch N 523/03 (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 attempting 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 roller shutter switch
N 523/03 (D1).
Note
When removing the bus terminal, there is a danger of
short circuits.
Plugging in the bus terminal (Figure 3)
Place the bus terminal (D2) in the guide slot and
-
press downwards 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 then plug in the terminal (D2) (red = +,
black = -).
Disconnecting the bus cable (Figure 3)
Remove the bus terminal (D2) and the conductor
-
(D2.4) from the bus cable by rotating them simul-
taneously backwards and forwards.
