Electrical connection
.
Work on the electrical system or equipment must only be
carried out by a skilled electrician himself or by specially
instructed personnel under the control and supervision of
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, please refer to appendix A)
Make sure to respect electromagnetic compatibility (EMC) when installing cables:
Signal and bus cables are susceptible to interference. Electric power cables,
in particular motor cables, are interference sources.
.
Lay cables being susceptible to interference or sources of interference at
the highest possible distance from each other.
.
The interference immunity of signal and bus cables increases if the cables
are laid close to the ground potential, e.g in corners of cable duct close to
ground surfaces.
.
If possible, avoid laying long cables and make sure that they are installed
in areas being subject to low interference.
.
Avoid long parallel paths with cables being either susceptible to interfer-
ence or interference sources.

Power supply (standard)
For explosion-proof version (type designation: AMExB/ AMExC), please
refer to page 8 or page 10.
.
Check whether type of current, supply voltage, and frequency comply with
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 plug cover
(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 instructions. 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).
A special parking frame (figure B-2) for protection against touching the bare
contacts and against environmental influences, in case the electrical
connection has been removed, is available.
