Means of protection (MOPs)
Declared MEANS OF PROTECTION (to be confirmed with test reports for every
particular part number):
Path MOPs Path MOPs
Insulation of Input wires 2x MOPP @ 340Vpk Input-to-Output
1x MOOP @ Working
voltage (depends on
modification)
Input-to-chassis 2x MOPP @ 340Vpk Input-to-Interface
1x MOOP @ Working
voltage (depends on
modification)
Input-to-input (opposite
polarity before fuses)
1x MOOP @ 340Vpk Output-to-chassis
Output negative is
intentionally connected
to the chassis
Mains part-to-chassis 1x MOPP @ 420Vpk Output-to-Interface
Interface is galvanically
connected to the output
Mains part-to-secondary
circuits
1x MOOP @ Working
voltage (depends on
modification)
Insulation of Output wires
2x MOPP @ Output
voltage (depends on
modification)
Besides, module must be protectively grounded, which is considered as 1x MOPP.
