The A06B-6087-H126 is a 200V/230V Power Supply Module (PSM-26) that is designed to provide the main power supply. The module uses power regneratation that returns energy to the power supply during motor deceleration (regeneration).
The following is the wiring diagram for the A06B-6087-H126. With the PSM-26, always install the circuit breakers, magnetic contactor, and AC reactor. To protect the equipment from lightning surge voltages, install a lightning surge protector across each pair of power lines and across each power line and the grounding line at the power inlet of the power magnetic cabinet. Always connect the control power supply cable to the CX1A. If it is connected to the CX1B, fuses inside the A06B-6087-H126 may blow.
