*1
When the PG current consumption exceeds 300 mA, use an external power supply and set a jumper cap at the EXT side on jumper J1. (Refer to
Section 6 "Configuration".)
*2
Use an external power supply whose rating meets the allowable voltage range of the PG. Regulate the external power supply voltage within the PI
voltage range (upper limit +10%), taking into account the voltage drop caused by the PG-inverter wiring impedance. Or, use a wire with a larger
diameter. (Refer to Table5.2)
*3
If the PO voltage level falls below the allowable voltage range of the PG due to voltage drop caused by PG-inverter wiring impedance, use an
external power supply or a wire with a larger diameter.
*4 *5
The PG interface card has two [PO] terminals and three [CM] terminals, each of which is conducting inside the card.
