Cronologic xTDC4, User Manual

Page: 32 / 32

All power supplied to the system must be turned off before installing the board.
When handling the board, adequate measures have to be taken to protect the circuits against
electrostatic discharge (ESD).
5.3.3 Cooling
The xTDC4 in its base configuration has passive cooling that requires a certain amount of air
flow. If the case design can’t provide enough air flow to the board, a slot cooler like Zalman
ZM-SC100 can be placed next to the board. Active cooling is also available as an option to the
board.
5.3.4 Environmental Conditions
The board is designed to be operated under the following conditions:
Symbol Parameter Min Typical Max Units
T ambient temperature 5 40
◦
C
RH relative humidity at 31
◦
C 20 75 %
and shall be stored between operation under the following conditions:
Symbol Parameter Min Typical Max Units
T ambient temperature -30 60
◦
C
RH relative humidity at 31
◦
C non condensing 10 70 %
5.3.5 Inputs
All inputs are AC coupled. The inputs have very high input bandwidth requirements and
therefore there are no circuits that provide over voltage protection for these signals. Any voltage
on the inputs above 5V or below -5V relative to the voltage of the slot cover can result in
permanent damage to the board.
5.3.6 Recycling
cronologic is registered with the “Stiftung Elektro-Altger¨ ate Register” as a manufacturer of
electronic systems with Registration ID DE 77895909.
The xTDC4 belongs to category 9, “ ¨ Uberwachungs und Kontrollinstrumente f¨ ur ausschlielich
