When the temperature is low, violent impact or vibration may damage the
plastic cable sheathing. To ensure safety, comply with the following
requirements:
– Cables can be laid or installed only when the temperature is higher than
0°C. Handle cables with caution, especially at a low temperature.
– Cables stored at subzero temperatures must be stored at room
temperature for at least 24 hours before they are laid out.
Do not perform any improper operations, for example, dropping cables
directly from a vehicle. Otherwise, the cable performance may deteriorate due
to cable damage, which affects the current-carrying capacity and temperature
rise.
NO TICE
Wear ESD gloves or a well-grounded ESD wrist strap when touching the
device or handling boards or application-specific integrated circuits (ASICs).
When holding a board, hold its edge without touching any components. Do
not touch the components with your bare hands.
Package boards with ESD packaging materials before storing or transporting
them.
