NV350 Handbook
Outputs that are not ES1 are hazardous and must not be made user accessible. They must be guarded or a
deflector fitted during installation to avoid a service engineer making inadvertent contact with the output
terminals, or dropping a tool onto them.
All outputs have operational spacings to earth, and due consideration must be given to this in the end product
design.
Adjusting output voltage beyond the stated range may cause over voltage protection (OVP) to operate, whereby
the output will turn off. To reset OVP, turn back the output voltage adjustment and remove the mains supply for
30 seconds and then switch back on.
