Wiring procedure
1) Remove set screws on the side before taking off the front panel toward the direction.
A explosion-proof breaker must be installed.
2) Connect wires to the terminal block correctly and fix the wires with a wire clamp equipped nearby the terminal block.
3) Route the wires in a proper way and penetrate the wires through the opening for electrical wiring on the side panel.
