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.
MB 80 INSTALLATION INSTRUCTIONS
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.
CPE 80 INSTALLATION INSTRUCTIONS
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.
