Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement
1003
Warning
To prevent accidental discharge in the event of a power line cross, route on-premise wiring away from power
cables and off-premise wiring, or use a grounded shield to separate the on-premise wiring from the power cables
and off-premise wiring. A power line cross is an event, such as a lightning strike, that causes a power surge.
Off-premise wiring is designed to withstand power line crosses. On-premise wiring is protected from power line
crosses by a device that provides overcurrent and overvoltage protection. Nevertheless, if the on-premise wiring
is in close proximity to, or not shielded from, the off-premise wiring or power cables during a lightning strike or
power surge, the on-premise wiring can carry a dangerous discharge to the attached interface, equipment, and
nearby personnel. Statement 338
Warning
For connections outside the building where the equipment is installed, the following ports must be connected
through an approved network termination unit with integral circuit protection.
FXS/T3/E3 Statement 1044
Warning
This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the
RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated
circuit-board when the ringer is active. The ringer is activated by an incoming call. Statement 1042
Warning
This equipment needs to be grounded. Use a green and yellow 12 to 14 AWG ground wire to connect the host to
earth ground during normal use. Statement 242
Warning
The importance of proper grounding cannot be overemphasized. It will minimize the potential for damage to your
system and maximize safety at the system site. We recommend you consult a licensed electrician or your local
electric utility company if you have any questions. Statement 269
Warning
A ground wire must always be a single piece of wire. Never splice two wires together for a ground. Corrosion and
weathering can lead to a poor connection at the splice, making the ground ineffective and dangerous. Statement
270
Warning
This unit is intended to be mounted on a wall. Please read the wall mounting instructions carefully before
beginning installation. Failure to use the correct hardware or to follow the correct procedures could result in a
hazardous situation to people and damage to the system. Statement 248
Warning
AC connected units must have a permanent ground connection in addition to the power cable ground wire.
NEBS-compliant grounding satisfies this requirement. Statement 284
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure
that the system remains stable. The following guidelines are provided to ensure your safety:
This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
