NOTES:
• The voltmeter measurement between the Tip and Ring should
be between 48 and 53 Vdc.
• Never run data wires and high voltage wires in the same
conduit. The high voltage wires may interfere with the data
wires and cause the system to malfunction.
• Reversed polarity will not damage the unit, however, some
telephones will not function properly.

Many phone companies have updated their color standards due to
the use of Cat 5 cable for most phone line installs, and keep
residential and business installs in line with each other. In the new
standard, there is no green, red, black or yellow wires, they have
been replaced by white/blue, blue/white, white/orange, and
orange/white. If the wire is primarily orange with white stripes
then that color is orange/white. Refer to the table below. The NID
labels will most likely have the old coloring scheme on them, and
most telephone wiring components you can purchase will still
reflect the original colors.
NOTE: If the unit will be connected with an
alarm system, you must connect the telephone
line to the alarm system first in the series from
the Telco box. If the units are not connected in
this order, they will not operate properly.

Ensure that the unit is grounded properly. The unit contains a
number of static sensitive components that can be damaged by
static discharge.
To AVOID damaging gas, power or other underground utility
lines, contact underground utility locating companies BEFORE
digging.
NOTES:
• Use a minimum of 12 gauge wire in most cases. The type and
length of the earth ground rods vary by region. Contact the
building inspector’s office in the municipality where you plan to
install the unit for correct grounding materials and installation
procedures.
• Do not ground the unit to a pedestal post (gooseneck) if one is
used.

POWER WIRING
The 110 Vac outlet must be dedicated to the unit only. This outlet
should be wired back to its own 10 Amp minimum circuit
breaker. This will prevent two problems:
• Other equipment cannot introduce spikes, noise, surges, or
dips into the power circuit.
• The system’s operation will not be affected if any other
equipment develops a short circuit across the power line.
Connect the transformer into a 110 Vac outlet after all
connections have been made, any other type of outlet will cause
damage to the system.
