3�2�2 Fieldbus connection
1. Dismantleeldbusconnectionhousing(g.,
item 2) and connection cover (4).
2. Unscrewplugelement(1)fromeldbuscon-
nection housing (2).
3. Unscrew screw plugs from the required cable
glands in the connection hood.
4. Screw in the cable glands (5) only slightly and
insert the connecting cables (6).
Foreldbuscables,cableglandswithout
shieldaresufcient,refertopoint7below.
5. Connect the mains cables and, if required,
signal cables in accordance with the circuit
diagram enclosed in the connection housing,
connecting the earth lead conductor to the
provided terminal in the connection box.
6. Fitplugelement(1)intoeldbusconnection
housing (2) again.
7. Connecteldbusconnecting cables to the
bus termination PCB (3). Lead shielding (7)
under metal clamp (8).
8. Fitconnectioncover(4)andeldbusconnec-
tion housing (2) again.
9. Tighten cable glands (5).
a = If the actuator is the last device of the bus
segment, the termination resistor must be
set to ON or a termination must be done
externally.
b = Connection for external 24 V power supply.
Enables communication even if the mains
are disconnected.
c = Connection for PROFIBUS DP bus monitor
(Protocol Analyzer).

3�2�3 External potential conductor connection
The external potential conductor connection
can be used for functional grounding and not for
protective grounding.
1. Remove plastic fastener (1) from the elec-
tronics housing.
2. Fit potential conductor (4) and gripping disc
(5) (shims point in direction of the housing!)
with M5 screw (2) and washer (3).
