ELECTROSTATIC DISCHARGE (ESD)
Many electronic components are sensitive to static electricity. Voltages so low that they cannot be felt,
seen or heard, can reduce the life, affect performance, or completely destroy sensitive electronic
components. When performing service, proper ESD equipment should be used to prevent possible
damage from occurring.
All units are manufactured with input and output busbars at the bottom of the unit as standard. The input and/or
output busbars can be moved to the top of the unit if required.
