SAFETY CONSIDERATION NOTES:
1. Protective bonding conductor from the end product protective earthing terminal must be tied to TB1. For optimum EMI performance, 4 mounting holes
must be tied to the end product protective earthing terminal.
2. This power supply requires mounting on standoffs minimum 6mm in height. If there is risk of chassis deformation or shorter standoff height is
required, an appropriate insulator must be used under the power supply with adequate extension beyond the outline of the power supply. In all cases,
the applicable safety standards must be applied to ensure proper creepage and clearance requirements are met.
3. The primary heatsink is considered a live primary circuit, and should not be touched. Also, the primary and secondary heatsinks must be separated
with reinforced insulation. It is recommended that the primary heatsink be kept at least 3.5mm from chassis and 7mm from secondary circuits. In all
cases, the applicable safety standards must be applied to ensure proper creepage and clearance requirements are met.
4. This product is subject to the following operating requirements and the Life and Safety Critical Application Sales Policy: Refer to:
