About This Guide
Cautions
Lightening Protection Installation Warning
Caution
Lightning protection or grounding blocks are required to isolate or protect the in-building equipment
from the hazards associated with the outside plant or outside environment. Lightning protectors
and/or grounding blocks are normally installed outside the building just prior to the coaxial cable
entering the building.
Power Supply Disconnection Warning
Caution
Before working on a chassis or working near power supplies, unplug the power cord on AC units;
disconnect the power at the circuit breaker on DC units.
Jewelry Removal Warning
Caution
Before working on equipment that is connected to power lines, remove jewelry (including rings,
necklaces, and watches). Metal objects will heat up when connected to power and ground and can
cause serious burns or weld the metal object to the terminals.
AC Power Disconnection Warning
Caution
Before working on a chassis or working near power supplies, unplug the power cord on AC units.
TN Power Warning
