Temperature Sensing
Thermal sensors are located on one heatsink in the rectifier and one
heatsink in the inverter. The thermal sensors are mounted on the
heatsink with the temperature feedback circuit board.
1. Ensure there is no power to the equipment.
A T T E N T I O N A T T E N T I O N To prevent electrical shock, ensure the main
power has been disconnected before working on
the drive. Verify that all circuits are voltage free
using a hot stick or appropriate voltage-
measuring device. Failure to do so may result in
injury or death.
