(1) Power supply system wiring
Before switching on the main circuit and control circuit power supplies, check the following items.
(a) Power supply system wiring
1) The power supplied to the power input terminals (L1/L2/L3/L11/L21) of the driver should satisfy
the defined specifications. (Refer to section 1.3.)
2) between P3 and P4 should be connected.
