Removing the bus terminal
(Figure 4)
- The bus terminal block (E1) consists of two sections
(E1.1 and E1.2), each with four terminal contacts.
Care should be taken not to damage the two test
sockets (E1.3) 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 (E1) and pull the bus ter-
minal forwards out of the device (E2).
CAUTION
Care should be taken as there is a risk of to short circuit
the bus voltage when removing the bus terminal block
with a screwdriver.
Plugging in the bus terminal
(Figure 4)
- Place the bus terminal (E1) to the guide slot and
- push the device backwards until it reaches the stop.
Connecting the bus cable (Figure 4)
- The bus terminal (E1) is suitable for single core con-
ductors with 0.6 ... 0.8 mm Ø.
- Strip approx. 5 mm of the insulation from the conduc-
tors (E1.4) and plug in them into the terminal block
(E1) (red = +, black = -).
Disconnecting the bus cable (Figure 4)
- Remove the bus terminal block (E1) and the conduc-
