Safety Notes
ATCA-8330 Installation and Use (6806800S82B) 25
System Damage
The intra building port(s) of the equipment or subassembly is suitable for connection to intra
building wiring or cabling only (Type 2 or Type 4 ports as described in GR-1089- CORE, Issue 4)
and require isolation from the exposed OSP (Outside Plant) cabling.The addition of primary
protectors is not sufficient protection in order to connect these interfaces metallically to OSP
wiring.
The intra building port(s) of the equipment or subassembly must not be metallically
connected to interfaces that connect to the OSP or its wiring.
Operation
Blade Damage
Blade surface
High humidity and condensation on the blade surface causes short circuits.
Do not operate the blade outside the specified environmental limits. Make sure the blade is
completely dry and there is no moisture on any surface before applying power.
Blade Overheating and Blade Damage
Operating the blade without forced air cooling may lead to blade overheating and thus blade
damage.
When operating the blade, make sure that forced air cooling is available in the shelf.
When operating the blade in areas of electromagnetic radiation ensure that the blade is bolted
on the system and the system is shielded by enclosure.
Injuries or Short Circuits
Blade or power supply
In case the O-Ring 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.
