2.
Insert the alternative connection piece. In doing so, pay
attention to the latching lugs.
3.
Turn the connection piece clockwise until it clicks into
position.

2.
Insert the alternative connection piece. The connection
for the air supply can point to the left- or the right-hand
side. In doing so, pay attention to the latching lugs.
3.
Turn the connection piece clockwise until it clicks into
position.

Electrical installation
Only qualified electricians may carry out the electrical install-
ation.
Danger!
Risk of death from electric shock!
Mains connection terminals L and N remain
live even if the on/off switch is turned off.
▶
Switch off the power supply.
▶
Secure the power supply against being
switched on again.
5.10.1 Opening the electronics box
A
B
▶
Open the electronics box as shown in the illustration.
5.10.2 Carrying out the wiring
Caution.
Risk of material damage caused by incor-
rect installation.
Mains voltage at incorrect terminals and plug
terminals may destroy the electronics.
▶
Do not connect any mains voltage to the
eBUS terminals (+/-).
▶
Only connect the mains connection cable
to the terminals marked for the purpose.
1.
Route the connection cables of the components to be
connected through the grommet provided on the under-
side of the product on the left.
2.
Use strain reliefs.
3.
If required, shorten the connection cables.
30 mm
≤
4.
Strip the flexible line as shown in the figure. In doing so,
ensure that the insulation on the individual conductors
is not damaged.
5.
Only strip inner conductors just enough to establish
good, sound connections.
6.
To avoid short circuits resulting from loose individual
wires, fit conductor end sleeves on the stripped ends of
the conductors.
7.
Screw the respective plug to the connection cable.
8.
Check whether all conductors are sitting mechanically
securely in the terminals of the plug. Remedy this if
necessary.
9.
Plug the plug into the associated PCB slot; see the wir-
ing diagram in the appendix.
5.10.3 Establishing the power supply
Caution.
Risk of material damage due to high con-
nected voltage.
At mains voltages greater than 253 V, elec-
tronic components may be damaged.
▶
Make sure that the rated voltage of the
mains is 230 V.
1.
Plug the mains plug into a suitable plug socket.
2.
Make sure that access to the power supply is always
available and is not covered or blocked.
