ALL DIMENSIONS ARE IN MM [IN].
SAFETY CONSIDERATION NOTES:
1. Protective bonding conductor from the end product protective earthing terminal must be tied to TB1. For optimum EMI performance, while maintaining
Class I safety isolation all 4 mounting holes must be tied to the end product protective earthing terminal. To maintain Class II safety isolation mounting
holes MTG1 and MTG2 need to be isolated from protective earth and should use standoffs of non-conductive material.
2. This power supply requires mounting standoffs of 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. 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:
http://www.murata-ps.com/requirements/
5. Used only in non-tropical conditions.
6. Double pole/neutral fusing.
