Installation mode
Soft start should be installed vertically, not upside down, obliquely or horizontally. Please install it on a firm structure with screws:
Heat should be generated during soft start operation. In order to ensure the passage of quasi-moving air, a certain space is reserved in the design. The generated heat is emitted upwards, so don't install it under heat-resistant equipment.
