Breaker’s operating characteristic
Be sure to lock out and tag out the breaker of the facility power supply
(customer power supply facility) before wiring.
Be sure to connect the power supply cable from the product side first,
and then connect the breaker of the facility power supply (the user’s
machine power supply).
When the panel is removed or mouted, be sure to wear protective
shoes and gloves to prevent injury with the edge of the panel.
A breaker that has the operating characteristic below is installed. Please use a
breaker that has the same or longer operating time as/than this for the customer
side (primary side). If it is a shorter operating time, there is a possibility of
accidental breaker trip due to the internal motors’ inrush currents of this product.
