ATTENTION: Risk of equipment damage exists. When attaching the
1769-SM1 module to a Compact I/O system, it is very important that
the bus connectors are securely locked together to ensure proper
electrical connection. Failure to do this may cause an electrical arc,
which can cause personal injury or equipment damage.
