Lightning/Surge Protection - Bin Master C-100-R Operator's Manual

3.4 Lightning/Surge Protection

All electronic devices connected to a large wired network are susceptible to damage from lightning and
other sources of electrical surges. Both the power source and an RS-485 network are a means for
electrical surges to enter the C-100-R control console and do damage. Although some level of protection
from electrical surges is built into the C-100-R control console, there are options to further protecting your
investment.
1. As recommended for the power connection at CN8, use an isolated power source and verify that
the output is NOT grounded or referenced to earth. Make sure that all devices connected to
either the sensor network or Expansion network uses a separate power source.
2. Be sure to connect the terminal at CN8 marked
wire or larger. This wire should be as short as possible to earth with no sharp bends or loops in
the wiring.
3. Use additional external lightning/surge arrestors on the RS-485 networks. This is very critical of
large outdoor networks that are high off the ground. Place 1 to 3 surge arrestors on the RS-485
network evenly spaced apart, following the manufacturer's installation instructions and using a
good quality connection to earth.
4. Consider using BinMaster wireless solutions that not only greatly protect your investment from
lightning but can reduce installation time and eliminate the need for running long lengths of RS-
485 cable. Call BinMaster and speak with one of our applications specialist for more information
on our wireless solutions.
