A 50 to 500 Vcc limited power source may be present on connector
R/T/R1/T1 when the unit is testing isolation resistance. Use with
caution.
These connections are intended for the express purpose of electrical
testing of common telephone line conductors, within the ranges
specified in the Technical Specifications on page 265. The device is
not intended to be used on telephone lines having voltages greater
than 280 VAC or 400 VDC, and it is also not intended to be used on
power distribution circuits.
The unit is protected against damage caused by fault voltages that
may be present on lines under test. Do not connect the unit if the
maximum expected fault voltage is greater than 500 volts.
