Personal Injury
Removing power from the PEMs cannot be accomplished by pushing the PEM's breakers to the
OFF position. The PEMs remain powered until the -48 VDC power to each PEM is completely
removed.
Make sure you disconnect the power at the external source and allow the capacitors in the PEM
to discharge (1 minute) before removing the PEM from the chassis.
Personal Injury (AdvancedTCA)
Hot PEMs may cause injury.
Allow the PEM to cool before servicing.
Personal Injury (microTCA)
Hot power modules may cause injury.
Allow the power modules to cool before servicing.
System Damage
Inserting or extracting the PEM with the PEM breaker in the ON position may damage your
system.
If power is connected to the shelf, make sure the PEM breaker is in the OFF position before you
insert or extract a PEM.
System Damage
Applying feed power to the PEM with the PEM breaker in the ON position may damage your
system.
Make sure the PEM breaker is in the OFF position when you turn on the feed power.
PEM Damage
Applying reversal power to the PEM causes damage to the electrolytic capacitors of the filter.
This is indicated by the red reverse power LED.
Only push the breakers to the ON position if the reverse power LED (red) is not lit.
