6.3.3 Cooling
The Ndigo5G 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.
6.3.4 Environmental Conditions
Temperature, Humidity
6.3.5 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.
6.3.6 Recycling
cronologic is registered with the “Stiftung Elektro-Altger¨ate Register” as a manufacturer of
electronic systems with Registration ID DE 77895909.
The Ndigo5G belongs to category 9, “
¨
Uberwachungs und Kontrollinstrumente f¨ur ausschlielich
gewerbliche Nutzung”. The last owner of a Ndigo5G must recycle it or treat the board in
compliance with 11 and 12 of the German ElektroG or return it to cronologic at the address
listed on page 47.
