•
Avoid ground loops via the sensor cables by preferably connecting the shield
at the IMx-end.
•
Ensure the metal/EMC cable gland has a good connection to the metal box
(nut or washer must penetrate the paint or coating on the box).
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.
1.4 External antenna for LTE/GSM/Wi-fi (optional)
SKF offer an optional external antenna that supports both Wi-Fi and LTE 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
1.5 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-16Plus can use position data to collate and associate with the condition
monitoring measurements. The GPS data is requested by the IMx-16Plus, acting as
a Modbus RTU master on the RS485, two wire serial interface.
Note that when configured for full GPS support in @Observer (position and other
measurement data stored together), only this single Modbus slave is supported (no
multiple slave support).
