INSTALLATION INSTRUCTIONS
There are five (5) terminals on both the
line
and
equipment
side of the
232E - four data line terminals and two ground terminals. Both ground
terminals, as shown on the label, are 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 data lines are cut or disconnected from the equipment to insert
the 232E product. The
line
side of the terminals are to be connected to
data lines from the outside world or 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.
Protectors should be installed at both ends of the data lines, at the point
of entry to buildings. Use the shortest possible connection to a low
impedance earth ground. Proper grounding and bonding are essential
for computer installation applications.
The 232B circuit board requires an edge connector interface for
installation. The circuit board should be located at the building interface
for incoming lines from the outside world.
Both the 232B and 232E can be mounted on a data line circuit panel,
which must be hard wired to the incoming data lines. Unprotected input
lines and ground wires are to be separated from protected output lines to
prevent electromagnetic coupling of noise from high transient currents on
the input lines.
ProTek’s data line protector is designed with a short circuit failure mode
to give maximum protection. A fuse, fussable link, or circuit breaker is
recommended for each data/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.
