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.
