20. WIRING MISTAKE PREVENTION
Improved quality of installation work through adoption of an “Connection error prevention” circuit which prevents wiring mistakes
Connection errors with the control wires and the power supply wires will not only contribute to burning-out of the control circuit board, but
can also cause large-scale working losses and affect reliability. If a circuit board with a “Connection error prevention” circuit is used, the
relay will not operate if the wires have been connected incorrectly, so that current will not flow to the control circuit board. This is designed
principally to eliminate human error at the installation site.
