Important
–
To avoid ground loops, SKF recommends connecting the shield
only at the IMx-end.
If the application does not allow that type of gland, it is possible to use isolated
(normally plastic) cable glands, but then care must be taken to:
•
Ensure shield grounding is performed in a way that avoids both EMC noise
and ground loops.
What to select for best performance (isolated plastic or EMC metal cable glands), is
very application specific and needs to be evaluated in each case by/together with the
customer.
Important - All unused cable openings must remain closed with blind plugs.
1.5 External antenna for mobile data/Wi-Fi (optional)
For use with an IMx-8Plus, SKF offer an optional external antenna that supports both
Wi-Fi and mobile data connectivity, noting that the mobile data and Wi-Fi interfaces
cannot be used simultaneously.
The antenna is designed to be mounted externally on the cabinet and connects to
both LTE connections and the Wi-Fi connection. See section
1.6 GPS module (optional)
An optional GPS module is available, see section
. This has an integral antenna,
but the module itself must be fitted external to any IMx cabinet.
The IMx can use position data to collate and associate with the condition monitoring
measurements. The GPS data is requested by the IMx, acting as a Modbus RTU
master on the RS485, two-wire serial interface.
Note that when configured for full GPS support in @ptitude Observer so that position
and other measurement data are stored together, only this single Modbus slave is
supported, there is no multiple slave support.
Connections for the GPS module
are available on the ‘top’
end cap of the
IMx-8/IMx-8Plus, refer section
