NVM175 Handbook
Primary mains circuits to secondary: 5.66kVDC*
Secondary circuits to earth: 2.515 to 2.525kVDC
*Important Note: This test is not possible with Y capacitors fitted to the unit as damage to these
capacitors may occur.
Routine Dielectric Strength testing is carried out as follows: Primary mains circuit to Secondary circuits and
earth – 2.515kVdc to 2.615kVdc. Secondary circuits to earth 2.25kVdc to 2.35kVdc
Safety Approvals:
UL60950-1, UL62368-1 and CSA22.2 No.60950-1 - UL Recognised. C-UL for Canada.
IEC / EN60950-1 - CE mark.
IEC/EN60950-1, IEC/EN 62368-1 and IEC/EN60601-1 - CB Report and Certificate.
CE marking when applied to any NVM175 or NVM175D product indicates compliance with the Low Voltage
Directive in that it complies with EN60950-1and with the ROHS Directive.
UL/CSA 60601-1 - UL + C -UL approval
Fusing: Internal fuses (F1): dual fuses in the L and N line (except single fuse in the L line for the –FL option),
T3.15AH, 250V, 5x20mm.
