Mounting and unmounting a DIN rail
mounted device
Slipping off bus connection blocks (Figure 4)
The bus connection block (D2) consists of two
components (D2.1 and D2.2) with four terminal
contacts each. Take care not to damage the two
test sockets (D2.3) by accidentally connecting
them to the bus cable or with the screw-driver
(e.g. when attempting to unplug the bus connec-
tion block).
Carefully put the screw-driver to the wire-insert-
ing slit of the bus connection block's grey compo-
nent and pull the bus connection block (D2) from
the device (D1).
Slipping on bus connection blocks (Figure 4)
Slip the bus connection block onto the guide slot
and
press the bus connection block (D2) down to the
stop.
Connecting bus cables (Figure 4)
The bus connection block (D2) can be used with
single core conductors Ø 0.6 ... 0.8 mm.
Remove approx. 5 mm of insulation from the con-
ductor (D2.4) and plug it into the bus connection
block (D2) (red = +, black = -).
Disconnecting bus cables (Figure 4)
Unplug the bus connection block (D1) and re-
move the bus cable conductor (D2.4) while simul-
taneously wiggling it.
