* - 5000m for 62368, 60950-1 and 60601-1 Edition 3 only, 3000m for other standards applicable.
Level of Insulation:
Primary mains circuits to earth: 2.25 – 2.35Kvdc.
Primary mains circuits to secondary and earth: 4.25 - 4.35kVDC**.
Primary mains circuits to transformer core: 4.25 - 4.35kVDC**.
Outputs to each other and to earth are isolated to 200VDC except CM modules which are 730 – 760Vdc to earth.
** This test is not possible with Y capacitors fitted to the unit as damage to RFI capacitors may occur.
Safety Approvals:
UL60950-1, UL62368-1 and CSA22.2 No.60950-1 - UL Recognised. C-UL for Canada.

IEC/EN60950-1, IEC/EN 62368-1, IEC/EN 61010-1 and IEC/EN60601-1 - CB Report and Certificate.
CE marking when applied to any NV350 product indicates compliance with the Low Voltage Directive in that it
complies with EN60950-1 and with the ROHS Directive.
UL/CSA 61010-1: UL + C–UL approval
UL/CSA 60601-1: UL + C–UL approval
Fuse: Internal fuse (F1): 6.3A/250V fast acting HBC, 5x20mm.
Symbols:
AC EARTH
If the earth terminal of the NV350 PSU is connected to the main incoming earth conductor of the end equipment, the
installer must cover the earth symbol with a label bearing the earth symbol of IEC60417-5019.
Note: All output voltages/variants may not be available as standard units, refer to datasheet for standard
