3-6
The typical main circuit wiring examples are shown below.
Single-phase 100 V, SGDV-F (SGDV-R70F, R90F, 2R1F, 2R8F)
• When turning ON the control power supply and the main circuit power supply, turn
them ON at the same time or after the control power supply. When turning OFF the
power supplies, first turn the power for the main circuit OFF and then turn OFF the
control power supply.
WARNING
• Do not touch the power terminals after turning OFF the power. High voltage may still remain in the SER-
VOPACK. When the voltage is discharged, the charge indicator will turn OFF. Make sure the charge indi-
cator is OFF before starting wiring or inspections.
