DEVICE CHARACTERISTICS
INSTALLATION INSTRUCTIONS
There are five (5) terminals on both the
line
and
equipment
side of the
TEL50E - four telcom line terminals and one ground terminal. The ground
terminal, as shown on the label, is connected internally. A single ground
connection is sufficient. However, it is recommended that both ground
connections be used for a lower impedance path to earth. This
connection can be made through the green AC power ground wire or a
known earth ground. The ground wire should be #14 stranded wire.
Incoming telcom lines are cut or disconnected from the equipment to
insert the TEL50E product. The
line
side of the terminals are to be
connected to outside telephone or telecommunication lines that carry the
transient threats into the equipment to be protected. The
equipment
side of the terminals are to be connected to the equipment to be
protected. The location of the product should be such that these wires
are as short as possible. A #18 or 20 gauge wire can be used for these
connections.
The TEL50B requires an edge connector interface for installation. A
standard 15 position edge connector can be used. When mounting or
wiring the connectors onto a printed circuit board, be sure that the
correct terminals are soldered. The line side of the board connections
are finger contacts 2 thru 5. The boards are conformal coated for limited
protection against moisture.
ProTek’s telcom line protector is designed with a short circuit failure mode
to give maximum protection. A fuse, PTC, fussable link, or circuit breaker
is recommended for each signal line on the input (line) side of the
protector for those applications that require an open circuit failure mode.
Caution:
A low DC resistance ground may not be indicative of a good
lightning ground. Lightning contains a broad spectrum of frequencies -
up to 1 MHz. A low impedance path to ground at the transient frequen-
cies is necessary. A ground strap is recommended or a #6 AWG
stranded wire. For wire lengths over 1.5 meters, there may be some
excessive line to earth potential under severe thunderstorm conditions.
For these applications, an additional protector may be necessary at the
equipment interface.
