NV350FEP Handbook
Level of Insulation:
Dielectric Strength testing is carried out as follows:
Primary mains circuit to earth - 2.25 - 2.35kVDC;
**Primary mains circuits to transformer core - 4.25 - 4.35kVDC;
**Primary mains circuits to secondary -4.25 - 4.35kVDC.
Outputs to each other and to earth are isolated to 200VDC.
(**This test is not possible with modules fitted to the unit as damage to RFI capacitors will occur).
Safety Approvals:
UL60950-1 and CSA22.2 No.60950-1 - UL Recognised. C-UL for Canada.
IEC / EN60950-1 - CE mark.
IEC/EN60950-1, 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 (2006/95/EC)
in that it complies with EN60950-1, and with Directive 2011/65/EU of the European Parliament and of the Council of
8 June 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment.
UL/CSA 61010-1 : UL + C–UL approval

Unit Configuration Code:
NV350 FEP or NF3 or NV-350FEP (these models are identical)
followed by: S, R, or C, where:
S
= Forward airflow, standard fan
R
= Reverse airflow, standard fan
C
= Customer air, fan not fitted
followed by: S or I, where:
S
= Screw input terminals
I
= IEC input
followed by: S, where:
S
= Standard Leakage (Class B Filter)
Unit configuration may be given using the above code and/or by the option description. The input terminal type
(screw or IEC) may alternatively be determined by examination of the unit.
optionally followed by: ES#V or IS#V, where:
ES5V
=
AC good, PSU enable, 5-5.5V, 2A standby output
ES12V
=
AC good, PSU enable, 12-13.5V, 1A standby output
IS5V
=
AC good, PSU inhibit, 5-5.5V, 2A standby output
IS12V
=
AC good, PSU inhibit, 12-13.5V, 1A standby output
where # represents the standby output voltage.
The Global Options Inhibit and Enable functions permit the customer to turn off or on the main psu outputs and the
fan. The standby supply is for use by the customer and provides an SELV output that continues to operate when all
