For Delta’s panel mount power supplies PMT2 and PMR Series, the maximum recommended screw tightening torque for mounting holes using M3 screws is 7 kgf.cm (6.08 lbf.in), which is superior to the industrial standard of 5 kgf.cm (4.33 lbf.in) based on the same screw material.
To prevent the use of screws that do not meet industrial standards, potentially causing thread slippage or installation matching issues, Delta has updated the maximum recommended screw tightening torque in the datasheets and manuals from 4~7 kgf.cm (3.47~6.08 lbf.in) to 4~5 kgf.cm (3.47~4.33 lbf.in).
Please refer to the table below for more details. The updated datasheets and manuals are now available on the DeltaPSU website. Should you require any further clarification, please reach out to us via our Contact Us Form.
