Telephony Hardware Manual 13
Safety with Electricity
High Voltages
• Observe all safety regulations and read the warnings, cautions, and notes posted on
the equipment.
• Find the switch to power off the cabinet. Read the posted instructions.
• Ensure that equipment can not be powered from another source or controlled from
a different circuit breaker or disconnecting switch.
• When a procedure requires that you power off the system:
• Lock the wall box-switch in the off position.
• Attach a DO NOT OPERATE tag to the wall box-switch.
• Never assume that the power is turned off. Always check to ensure that a circuit
does not have power.
Note: Unit must have ground wire attached if trunks are attached and system is
unplugged.
• Do not work alone. Work with another person who knows the locations of the power-
off switches, especially if you are working with exposed electrical circuits. (See note
above.)
• Follow the instructions in the manual carefully, especially when working with circuits
that are powered. Disconnect power when instructed to do so in the procedures.
• Disconnect all power before working near power supplies unless otherwise instructed
by a maintenance procedure.
• Disconnect all power before installing changes in machine circuits unless otherwise
instructed by a maintenance procedure.
• High voltages capable of causing shock are used in this equipment. Be extremely
careful when measuring high voltages and when servicing cards, panels, and boards
while the system is powered on.
• Do not wear jewelry or other metal objects when working on the equipment.
• When possible, work with one hand so that a circuit is not created.
• Use caution when installing or modifying telephone lines. Never install telephone
wiring during an electrical storm.
• Never install a telephone jack where it can get wet unless the jack is specifically
designed for wet conditions.
• Never touch uninsulated telephone wires or terminals unless the telephone line has
been disconnected at the network interface.
