Power supply wiring
Connect power supply wiring to the two power supply 2-pin
connectors. Power supply structure consists of 2 systems, but it
can be used with both single power supply and separate power
supply.
Individual power supply for other units is not necessary.
Make sure of connection with the designated pin. Tighten the
connector securely to 0.5 to 0.6 Nm tightening torque.
