such an electrician and in accordance with the applicable
electrical engineering rules.
.
Installation regulations for Profibus DP must be observed
for the wiring (For literature references
refer to appendix D).
7.1 Power supply (standard) For explosion-proof version (type designation: ACExC) see page 15.
.
Check whether type of current, supply voltage and frequency correspond
to motor data (refer to name plate at motor).
.
Loosen bolts (50.01) (figure B-1) and remove connection housing.
.
Loosen screws (51.01) and remove socket carrier (51.0) from connection
housing (50.0).
.
Insert cable glands suitable for connecting cables.
(The enclosure protection stated on the name plate is only ensured if suit
-
able cable glands are used).
.
Seal cable entries which are not used with suitable plugs.
.
Connect cables according to order-related wiring diagram.
The wiring diagram applicable to the actuator is attached to the
handwheel in a weather-proof bag, together with the operation instruc
-
tions. In case the wiring diagram is not available, it can be obtained from
AUMA (state commission no. refer to name plate) or downloaded directly
from the Internet (www.auma.com).
7.2 Remote position transmitter For the connection of remote position transmitters (potentiometer, RWG)
screened cables must be used.
7.3 AUMATIC on wall bracket The AUMATIC can also be mounted separately from the actuator on a wall
bracket.
.
For the connection of actuator and AUMATIC on wall bracket, use suitable
flexible and screened connecting cables.
(Preconfectioned cables can be obtained from AUMA on request)
.
The permissible cable length between actuator and AUMATIC amounts to
max. 100 m.
.
Versions with potentiometer in the actuator are not suitable. Instead of the
potentiometer, a RWG has to be used in the actuator.
.
Connect the wires in correct phase sequence.
Check direction of rotation before switching on.
