Service access
For service or maintenance purposes access to the control unit may be
necessary.
n
Install the control unit and adjacent components in a way that
allows for access to all mounting points, cables etc. by service per-
sonnel.
Electrical noise may influence the control unit's operation.
n
Locate the control unit at least 300 mm (12 inches) from areas
which may transmit electrical noise.
Electrical noise may be caused by components such as e.g. trans-
formers, coils, drive amplifiers or relays.
n
To decrease the influence of electrical noise, mount
1.5 mm (0.06 inch) metal shields between the control unit and the
external electrical devices causing the noise. Connect the shields
to a PE rail.
n
Install noise suppression components for all coils, relays, valves,
switching units, motor windings, other operator display panels and
other RF noise producing devices.
n
Connect noise suppression components directly at the noise
source.
If the distance to noise suppression components is several
centimeters, use twisted pair cables to connect.
n
Make sure, that noise suppressing capacitors have a low
inductance and a good high frequency conductance.
n
Conduct power and signal lines separately in a distance of at least
10 cm.
n
When using mechanical cable guides, install additional metal
shields.
n
For all electrical installations, follow the rules of VDE 0113.
5.3 Installing analog axes
The following chapters provide instructions and examples for analog
axes installation. Due to the versatility of the control unit, not all pos-
sible configuration options can be covered in detail.
n
