Overview of AUMA electrical connections

SQRVEx 14.2 Control unit: electronic (MWG)
Safety measures and safety equipment must comply with the respectively valid
national on site specifications. All externally connected devices shall comply with
the relevant safety standards applicable for the place of installation.
We recommend using connecting cables and connecting terminals according
to rated current (I ) (refer to motor name plate or electrical data sheet).
N
For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
Use connecting cables, cable glands, reducers, blanking plugs with a minimum
temperature range of +80 °C.
To avoid contact corrosion, we recommend the use of sealing agents for cable
glands and blanking plugs made of metal.
For connecting cables exposed to UV radiation (outdoor installation), use UV
resistant cables.
For the connection of position transmitters, screened cables must be used.
Signal and fieldbus cables are susceptible to interference. Motor cables are
interference sources.
This product potentially causes high frequency interference!
The measures eliminating interference described hereafter must be observed
for cable installation in accordance with EMC.
Use shielded power cable and earth shield at both ends.
Lay cables being susceptible to interference or sources of interference at the
highest possible distance from each other.
The interference immunity of signal and fieldbus cables increases if the cables
are laid close to the earth potential.
If possible, avoid laying long cables and make sure that they are installed in
areas being subject to low interference.
Avoid parallel paths with little cable distance of cables being either susceptible
to interference or interference sources.
In a residential environment, this product may cause radio interference, in which
case supplementary mitigation measures might be required.
This device is equipped with a network port.
Table 10:
Cable recommendation
Only network cables suitable for Industrial Ethernet are to be used.
Minimum requirement
Cable recommendation
Prior to installation, please note:
Install network cables at a distance of minimum 20 cm to other cables.
If possible, network cables should be laid in a separate, conductive, and earthed
cable tray.
Ensure absence of equipotential earth bonding differences between the indi-
vidual devices within the network (perform an equipotential earth bonding).
Do not use network hubs.
