Selection & installation notes
- Body length and mass above come from the image. The text contains different dimensions explicitly described as estimates; obtain the exact full outline and cable-variant mass.
- Inrush duration and test voltage are not supplied. Coordinate upstream protection with the manufacturer rather than treating inrush as continuous current.
- The image specifies spring terminals, while a text instruction discusses screw tightening. Wire ranges and AWG equivalents also differ. Follow the exact terminal markings.
- The source claims Class II and separately requires earthing. Confirm the protective class and earth connection. Do not infer dust protection from the fanless design.
- Keep the heater convection path clear, use ON/OFF control and avoid touching hot surfaces. External cabinet ventilation requirements depend on the installation.
