Slipping off bus connection blocks (Figure 3)
The bus connection block (D2) is situated on the top of
-
the device (D1).
The bus connection block (D2) consists of two com-
-
ponents (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 ca-
ble or with the screw-driver (e.g. when attempting to
unplug the bus connection block).
Carefully put the screw-driver to the wire-inserting slit
-
of the bus connection block's grey component and
pull the bus connection block (D2) from the device
(D1).
Slipping on bus connection blocks (Figure 3)
Slip the bus connection block onto the guide slot and
-
press the bus connection block (D2) down to the stop.

Connecting bus cables (Figure 3)
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 conduc-
-
tor (D2.4) and plug it into the bus connection block
(D2) (red = +, black = -).
Disconnecting bus cables (Figure 3)
Unplug the bus connection block (E1) and remove the
-
bus cable conductor (E1.4) while simultaneously wig-
