4.5
Use caution when working with telephone lines. They can
support dangerous voltages. 50VDC is often present, and
100VAC may be present during ringing. Additionally, tele-
phone lines may support dangerous levels of common mode
voltages. In some circumstances, user injury may result.
4.6
Use caution when working with any long unconnected wire
or cable. Under some conditions, unconnected wires may
“float up” to dangerous potentials, and touching them may
result in user injury.
4.7
Use care when connecting the FOX to any wire or cable. An
unexpected dangerous voltage may be present, which may
result in injury to the user.
4.8
Potentials applied to any connection of the FOX may appear
on other FOX connections. For example, a potential applied
to the RJ-11 plug may appear on the alligator clips. This
could pose a shock hazard to the user, if for example, a tele-
phone cable with 120VAC on it is connected to the FOX . The
120VAC may appear on the alligator clips, and shock the
user.
