Cooling
The NI PS-15 is convection cooled, and direct cooling is not required.

conduits) by more than 30%.
Proper installation clearance for the NI PS-15 is 40 mm on top, 20 mm on
the bottom, 5 mm on the left and right side when loaded permanently with
full power. If the adjacent device is a heat source, 15 mm clearance is
recommended between the NI PS-15 and the adjacent device.
Hazardous Risks
Cautions
Do not use the unit without the proper earth connection (Protective Earth).
Use the PE pin on the front panel terminal block for earth connection instead of one of the
screws on the housing.
Turn the power off before working on the power supply. Protect against inadvertent
re-powering.
Make sure the wiring is correct by following all local and national codes.
Do not open, modify, or repair the unit.
Use caution to prevent any foreign objects from entering into the housing.
Do not use in wet locations or in areas where moisture or condensation can be expected.
Service Parts
The NI PS-15 power supply does not contain any serviceable parts.
If an internal fuse trips, it is caused by an internal defect. If damage or
malfunction occurs during operation, immediately turn the power off
and send the NI PS-15 to National Instruments for inspection.

Attempting to repair or modify the NI PS-15 power supply will void your warranty.
