System Overheating
If you reduce the blower speed the system temperature will rise.
Constantly control the system temperature once you have reduced the blower speed.
While operating the system ensure that the environmental and power requirements are met.
Loss of Safety Approval for ATCA-715/7105/717/7107 and the System
If you use the ACC/CABLE/RJ45/DSUB in applications other than maintenance and if you use it
with devices not providing a protection according to EN 60950-1, you loose the safety
approval of the blade.
Therefore, only use the ACC/CABLE/RJ45/DSUB for maintenance and with devices providing a
protection according to EN 60950-1.
Injuries or Short Circuits
Blade or Power Supply
In case the ORing diodes of the blade fail, the blade may trigger a short circuit between input
line A and input line B so that line A remains powered even if it is disconnected from the power
supply circuit (and vice versa).
To avoid damage or injuries, always check that there is no more voltage on the line that has
been disconnected before continuing your work.
Expansion
System Overload
To avoid an overload of the system check the total power consumption of all components
installed (see the technical specification of the respective components). Ensure that any
individual output current of any source stays within its acceptable limits (see the technical
specification of the respective source).
Loss of Safety Compliance
Using of Additional Plug-in Blades
By using additional plug-in blades it may be possible that the system may be no more
compliant to safety and EMC regulations.
The system integrator has to ensure that the compliancy is guaranteed.
