Protect the system from heavy voltages on the trunk lines and the
overhead stations
• The ETERNITY GENX may be damaged by heavy voltages entering the system from trunk lines or from
overhead stations. These heavy voltages may enter the trunk lines and from overhead stations due to:
• Heavy voltage line falling on the CO line or on the overhead stations cable. A dangerous surge can
occur if a telephone line comes in contact with a power line.
• Lightning/Thunderbolts.
• To protect ETERNITY GENX from these voltages, use Primary Protection/Surge Protectors on the trunk
and long distance extension lines to protect the system from lightning and electrical surges.
• Install any standard Input Protection (punch down protection) on the Krone Modules of the MDF or the
"Primary Protection Module - PPM4"
overhead stations. The product Warranty does not cover damages resulting from heavy voltage on CO
lines and overhead stations!
• It is recommended that you install the PPM on the MDF, as MDF cables from the CO are terminated on the
System MDF.
Protect the system from Lightning
• To protect ETERNITY GENX from extremely high voltage currents associated with lightning strikes, install
a lightning protector on an outside (CO) line.
Protect the system from static charges
• Every person carries some static charge in his/her body depending upon body composition and the
environment around them. Most of the times, this charge finds its way to the earth when the person
touches any object which is grounded, or when the person is barefoot.
• Generally, persons installing or handling electronic and electrical equipment take precaution to wear
appropriate footwear to get protection from electric shocks. Doing so, the static charge accumulates in his/
her body and does not find its way to the ground. But when such a person touches any of the electronic
cards, the static charge finds its way through the electronic components thereby causing damage to the
cards.
• So, the person installing or servicing the system must provide a path to the static charges, by wearing an
antistatic belt, which is properly earthed.
Telecom Earth (Ground)
• The Earth (Ground) is the most important safety procedure to prevent electrical shocks and fires. It
protects from lightning strikes, electrical transients, static discharges, electromagnetic interference and
electrical hazards.
• Ensure that a proper electrical earth and a telecom earth are in place for the safety of people and the
system. Telecom earth is a dedicated earth for the ETERNITY GENX/any other telecom equipment.
