• Install equipment in Restricted Access Areas only (dedicated
equipment rooms/closets) in accordance with Articles 110-16,
110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.
• Connect equipment to a DC supply source (reliably earthed) that is
electrically isolated from the AC source.
• Directly connect the equipment chassis to the DC supply system-
grounding electrode conductor or a bonding jumper from a
grounding terminal bar (or bus) that is connected to the DC supply
system grounding electrode conductor.
• Contain equipment that has a connection between the grounded
conductor of the same DC supply circuit, the grounding conductor,
and also the point of grounding of the DC system in the same
immediate area. Do not ground the equipment elsewhere.
• Locate the DC supply source within the same premises as the
equipment.
• Route away and secure all DC input wiring from sharp edges to
prevent chaffing as well as provide strain relief.
• Provide a readily accessible disconnect device and protective
device a fixed wiring for a DC power supply suitable for the specified
rated voltage and current. Disconnect and protective devices to be
rated 2A Amps maximum.

To avoid contact with electrical current:
• Never install electrical wiring during an electrical storm.
• Never install telephone jacks in wet locations unless that jack is
specifically designed for wet locations.
• Use caution when installing or modifying telephone lines.
• Use a screwdriver and other tools with insulated handles.
• You and those around you should wear safety glasses or goggles.
• Do not place telephone wiring or connections in any conduit, outlet
or junction box containing electrical wiring.
• Installation of inside wire may bring you close to electrical wire,
conduit, terminals and other electrical facilities. Extreme caution
must be used to avoid electrical shock from such facilities. You must
avoid contact with all such facilities.
• Telephone wiring must be at least 6 feet from bare power wiring or
lightning rods and associated wires, and at least 6 inches from other
wire (antenna wires, doorbell wires, wires from transformers to neon
signs), steam or hot water pipes, and heating ducts.
Do not work on your telephone wiring if you wear a
pacemaker. Telephone lines carry electrical current.
