Hardware
Installation Before installing this board, ensure that the power drawn by this board, together
with the host and any auxiliary boards drawing power from the host, is within the
rating of the host power supply. Equipment must be installed such that, with the
exception of connections to the host, the clearance and creepage distances shown
in the following table are maintained between the board and other assemblies that
use or generate the voltages shown in the table. The larger distances shown in
(brackets) apply where the local environment within the host is subject to
conductive pollution or dry non-conductive pollution which could become
conductive due to condensation (Pollution Degree 3 environments). Failure to
maintain these minimum distances would invalidate the approval.
Note: Obtain advice from a telecommunications safety engineer for a host or other
expansion boards fitted in the host using or generating voltages greater than
300 V (rms or dc).
Safety Notices 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. Avoid contact with electrical current by
following these guidelines:
• Use tools with insulated handles.
• Do not place telephone wiring or connections in any conduit, outlet or junction
box containing electrical wiring.
Note: Do not work on your telephone wiring at all if you wear a pacemaker.
Telephone lines carry electrical current.
• 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.
• Before working with existing inside wiring, check all electrical outlets for a
square telephone dial light transformer and unplug it from the electrical
outlet. Failure to unplug all telephone transformers can cause electrical shock.
• Do not place a jack where it would allow a person to use the telephone while in
a bathtub, shower, swimming pool, or similar hazardous location.
• Protectors and grounding wire placed by the service provider must not be
connected to, removed, or modified by the customer.
Do not touch telephone wiring during lightning!
