GRT1-OD8-1 REFERENCE MANUAL ()

Soft-start Function Starts Motors Smoothly,
and Economically.
The soft-start function allows a smooth startup of motors by,
holding down the starting current, and functions like an inverter.
Comply with UL, CSA, IEC, and JEM requirements.
Mount with screws or to DIN tracks.
