These products are designed for continuous operation within an overall enclosure, and must be mounted such that
access to the mains terminals is restricted. See the appropriate standard listed above.
These products are NOT suitable for use in the presence of flammable anaesthetic mixtures with air or with oxygen,
or with nitrous oxide.
For IEC60601-1, EN60601-1 and UL/CSA 60601-1 (Second Edition standards), the NV350 range provides the
following levels of insulation: For PSU’s fitted with C and/or CM Modules only there is Reinforced insulation between
input and outputs. For all other PSU’s there is a basic insulation between input and outputs. For PSU’s fitted wiith
CM Modules only, there is basic insulation at the working voltage between the CM module outputs and earth
(provided that a CM module is not fitted in slot 1).
For IEC 60601-1:2005; EN 60601-1:2006; ANSI/AAMI ES 60601-1:2005; CSA 22.2 No 60601-1:2008), the NV350
range provides reinforced insulation between input and outputs (2 MOOPs) for all products. For PSU’s fitted wiith CM
Modules only, there is basic insulation at the working voltage between the CM module outputs and earth (1 MOPP)
(provided that a CM module is not fitted in slot 1).
Connect only apparatus complying with the standards listed above as appropriate to the signal ports.
All outputs are SELV except possibly when they are connected in series and depending on the total voltage.
These products are classed as ordinary equipment and are not protected against the ingre ss of water (IPX0).
Reference should be made to local regulations concerning the disposal of these product s at the end of their useful
life.
Where any part of this product is made accessible to the operator in the end use equipment, the operator must not
touch this part and the patient at the same time.
These products have not been assessed to IEC/EN60601-1-2 (EMC) but EMC test data is available from TDK-
Lambda UK Ltd.
WARNING: No modification of this product is allowed.
Except for permanently installed equipment, the overall equipment into which these products are installed must have
double pole fusing on the input mains supply. The products themselves have single pole fusing in the live line only.
Special Instructions for IEC/EN/UL/CSA 61010-1 Second Edition
Whilst all individual module single outputs are classed as SELV outputs in accordance with IEC/EN/60950 (<60Vdc
or 42.4V peak) serried combinations of these modules may exceed these values and become hazardou s output
voltages. For IEC/EN61010-1 the equivalent limits are 70Vdc, 33Vrms or 46.7V peak. Provided these levels are not
exceeded, the outputs are not considered hazardous for IEC/EN61010-1.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment
may be impaired.
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 NV350 earth symbol with a label bearing the earth symbol of IEC60417-5019.

Customer Air Cooling (options C or U
):
Customer Air Cooling:
The following method must be used for determining the safe operation of PSUs when C or U option (Customer Air) is
fitted, ie fan not fitted to PSU. The minimum permitted airflow for customer air cooling is 0.5m/s.
For PSUs cooled by customer supplied airflow the components listed in the following table must not exceed the
temperatures given. Additionally ratings specified for units with an internal fan must still be complied with, eg mains
input voltage range, maximum output power, module voltage / current ratings and maximum ambient temperature.
To determine the component temperatures the heating tests must be conducted in accordance with the requirements
of the appropriate standards.
Test requirements include: PSU to be fitted in its end-use equipment and operated under the most adverse
conditions permitted in the end-use equipment handbook/specification and which will result in the highest
temperatures in the PSU. To determine the most adverse conditions consideration should be given to the end use
equipment maximum operating ambient, the PSU/assembly loading and input voltage, ventilation, end use
equipment orientation, the position of doors & covers, etc. Temperatures should be monitored using type K fine wire
thermocouples (secured with cyanoacrylate adhesive, or similar) placed on the hottest part of the component (out of
any direct airflow) and the equipment should be run until all temperatures have stabilised.

Modules connected in series or parallel
Module outputs can be connected in series. See section on Module Limitations.
Module outputs cannot be paralleled to other modules in the same power supply or paralleled to other modules in
another unit.
Paralleling of modules for redundant operation i.e. Output load does not exceed the load current of single module.
This can be achieved by isolating the outputs using orring diodes.
With this method remote sensing around these diodes is not allowed.

Module limitations
• All outputs are SELV except under the following circumstance: Outputs connected in series are non-SELV if the
total output voltage + 30% of the max. Rated output voltage of the output with the highest rated voltage exceeds
60Vdc (the 30% addition allows for a single fault in any one individual channel).
• If the total voltage of outputs connected in series exceeds the 60Vdc SELV limit then all outputs must be
considered non-SELV.
• The total voltage of outputs connected in series must not exceed 160V.
• Non-SELV outputs 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.
