1.2 Precautions against damage to people
Do not work on the product with the
power on.
To avoid electrical discharge, this product must not be handled with
the system powered on and in any case it may not be operated
without protective covers.
1.3 Precautions against damage to the product
Do not insert / unplug cards or other
electronic elements when powered up
The connection/disconnection of the I/O’s when plugged to the
power could produce a sequence of connections that could damage
electronic components which had been previously connected to their
corresponding reference earth.
Do not force the connection tag strips
The connection tag strips are connected exerting a small pressure. If
you encounter difficulty to plug them this may mean that they are
upside down or not aligned. If they are forced, besides the damage
to the strip you can cause damages on the electronics.
Secure the ground connections quality.
All the ground connections must be star-type and with the suitable
section. Loop ground connections are potential receptor antennas
with capacity to generate important current peaks.
Use suitable packing material for
transportation
An electronic module with a lot of fragile components should be
transported with a good protection packaging. A collision can cause
damages that could appear long time after the start up.

sources, strong vibrations or high
humidity that exceeds the technical
specifications.
