Measures for preparation
5.2 Electrical connections
Risk of electric shock.
− Upon installation of the electric cables, you
are required to observe the regulations
concerning low-voltage installations ac-
cording to DINVDE0100 as well as the
regulations of your local power supplier.
− Use a suitable power supply which guar-
antees that no dangerous voltages reach
the device in normal operation or in the
event of a fault in the system or any other
system parts.
− Connect the actuator to the electrical net-
work only after the power supply is rst
switched off. Make sure the power cannot
be switched on unintentionally.
Risk of actuator damage due to incorrect
wiring of the binary inputs.
Always wire the binary inputs free of volt-
age.
5.2.1 Connecting the power
supply
Î Connect the wiring as shown in Fig.8.
Additionally, the terminal assignment de-
pends on the selected application (see
section8.4 on page45 and sec-
tion8.4.2 on page47).
Î Guide the cables to the spring-cage ter-
minals from the top.
Î Connect binary signals over oating con-
tacts.
After connecting the power supply on start-
ing up the actuator for the rst time, the start
screen and the error reading E00 "RUNT"
(no initialization performed) appear in alter-
nating sequence (see Fig.13 on
page36).
