General Electrical Safety Guidelines and Warnings
WARNING: Certain ports on the device are designed for use as intrabuilding
(within-the-building) interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE) and require isolation from the exposed outside plant (OSP) cabling. To
comply with NEBS requirements and protect against lightning surges and commercial
power disturbances, the intrabuilding ports must not be metallically connected to interfaces
that connect to the OSP or its wiring. The intrabuilding ports on the device are suitable
for connection to intrabuilding or unexposed wiring or cabling only. The addition of
primary protectors is not sufficient protection for connecting these interfaces metallically
to OSP wiring.
CAUTION: Before removing or installing components of a device, connect an electrostatic
discharge (ESD) grounding strap to an ESD point and wrap and fasten the other end of
the strap around your bare wrist. Failure to use an ESD grounding strap could result in
damage to the device.
•
Install the device in compliance with the following local, national, and international electrical codes:
•
United States—National Fire Protection Association (NFPA 70), United States National Electrical Code.
•
Other countries—International Electromechanical Commission (IEC) 60364, Part 1 through Part 7.
•
Evaluated to the TN power system.
•
Canada—Canadian Electrical Code, Part 1, CSA C22.1.
•
Locate the emergency power-off switch for the room in which you are working so that if an electrical
accident occurs, you can quickly turn off the power.
•
Make sure that grounding surfaces are cleaned and brought to a bright finish before grounding connections
are made.
•
Do not work alone if potentially hazardous conditions exist anywhere in your workspace.
•
Never assume that power is disconnected from a circuit. Always check the circuit before starting to
work.
•
Carefully look for possible hazards in your work area, such as moist floors, ungrounded power extension
cords, and missing safety grounds.
