MB 80 MOTHERBOARD
DESCRIPTION
The CPE 80 and MB 80 provides protection of 32 data lines using up to eight (8)
SPDs (surge protection device). These products accomodate a variety of SPDs
such as 232B, 422B and 420LB; which are not included with the motherboard
or enclosure. Available from ProTek Devices, each data line SPD has four, two
stage protection circuits. The SPDs provide primary and secondary protection
against lightning, inductive switching and ESD transient threats. The first stage
diverts the transient current through the ground terminal return part and the
second stage clamps the voltage to a safe level without interruption of service.
These interface board assemblies are located between the unprotected
transient threat environment (incoming data lines) and the protected sensitive
electronic equipment or system. The motherboard is marked identifying the
protected side. The unprotected side should be located away from the protected data line
cables.
The MB 80 is a motherboard containing eight (8) edge card connectors and two (2) strip
terminal blocks. The edge card connectors are soldered onto the motherboard, which is
connected to the terminal blocks by copper traces. The terminal blocks have screw type
connections for easy installation between the unprotected and the protected equipment.
Data line surge protection devices are inserted into the edge card connectors for protection
of sensitive equipment and/or systems.
The CPE 80 includes a motherboard (MB 80) inside a rugged, cast aluminum housing with
a removable cover. The housing contains two (2) holes on either side of the case for data
line cables. Mounting hardware is provided for the data line cables.

INSTALLATION INSTRUCTIONS
Maximum transient protection requires a good
ground system. This consists of a common
bonded or ground system, which interconnects AC
power and data line grounds. A single ground
connection is sufficient. However, it is more
important that the ground be a low impedance path
to the earth. A good earth connection is
necessary for lightning transient threat conditions.
Connections are usually best using a ground strap
where the cross-sectional area of the ground
connection is maximized. The ground connection
is made through the green AC power ground wire or
to a known earth ground system. If a ground wire
is used, it is recommended that it is a #14
stranded wire. A low impedence ground is
important to minimize a ground voltage potential
rise that may cause ground bounce within the
system or equipment.

1. Select a suitable mounting location within 10
meters of the protected equipment. An enclosure
is recommended to protect against dust and
moisture.
2. Mount the board using the stand-offs and #8
screws provided.
3. Connect wires to appropriate terminals as show
in Figures 1 and 2. The ground wire MUST be kept
on the unprotected side of the board.
4. Insert protected boards. Be certain to insert
boards in the correct position as shown on the MB
80.

1. Select a suitable mounting location within 10
meters of the protected equipment.
2. Remove the cover and install retainer
assembly in holes. Do not tighten gland nut
bushing. See cable retainer assembly detail in
Figure 1.
3. Install base on a flat surface using #8 screws
provided.
4. Insert wires through cable retainer assemblies
and connect to appropriate terminals as shown in
Figures 1 and 2. The ground wire MUST enter the
enclosure ONLY through the unprotected side.
5. After completion of wiring, hand tighten gland
nut bushing.
6. Insert protector boards. Be certain to insert
boards in the correct position as shown on the
printed circuit board.
7. Replace cover and tighten cover mounting
screws.
