CAUTION:
RMX-410x
series units are not authorized for use as critical component in nuclear control systems,
life support systems or equipment for use in hazardous environments without the express written
approval of the National Instruments.
OVERVOLTAGE CATEGORY AND ENVIRONMENTAL CONDITIONS
The RMX-410x series units have been evaluated to Overvoltage category II.
The RMX-410x series units are intended for use in the following operation conditions:
* Indoor use
* Pollution degree 2
* Max. operational altitude: 3000m above sea level
* Ambient temperature: 0°C-50°C.
GROUNDING
RMX-410X series units are Class I product.To minimize electrical shock hazard, the RMX-410xseries
units must be connected to an electrical ground. The instruments must be connected to the AC
power supply mains through a standard certified three-wire power cable, with the ground wire
firmly connected to an electrical ground (safety ground) at the power outlet. Any interruption of
the protective ground conductor or disconnection of the protective earth terminal will cause a
potential shock hazard that might cause personal injury.
LIVE CIRCUITS
Operating personnel must not remove the RMX-410x series unit cover.
No internal adjustment or component replacement is allowed by non-NI qualified service personnel.
Never replace components with power cable connected. To avoid injuries, always disconnect
power, discharge circuits and remove external voltage sources before touching components.

NATIONAL
INSTRUMENTS
PARTS SUBSTITUTIONS & MODIFICATIONS
Parts substitutions and modifications are by authorized NI service personnel only. For repairs or
modifications, the instrument must be returned to NI service facility.
AC INPUT
Do not connect RMX-410x series unit to mains supply exceeding the input voltage and frequency
rating. The input voltage and frequency rating is: 100-240V~, 50/60Hz. For safety reasons, the
mains supply voltage fluctuations should not exceed +/-10% of nominal voltage.
ENERGY HAZARD
The main output of RMX-410x series units is capable of providing hazardous energy. Due to
hazardous energy level the output and connections therefore must not be user accessible.
Manufacturer's final equipment must provide protection to service personnel against inadvertent
contact with output bus bars.
FUSE
Internal fuse is sized for fault protection and if a fuse was opened it would indicate that service is
required. Fuse replacement should be made by qualified technical personnel.
Refer to maintenance instructions in Chapter 10 for fuse ratings.
WARNING:
There is electric shock hazard when the power supply output is adjusted above 60VDC
Ensure that there is no possibility to touch simultaneously one of the output pins and earth (including
the power supply’s metal enclosure) nor to touch simultaneously one of the output pins and metal
parts of any external products supplied by the power supply when the output is adjusted above 60VDC.
Note: The protection provided by the RMX-410x can be impaired if it is used in a manner not
described in this document.

operation (CV/CC).
1.2.7 Parallel Operation
Up to six RMX-410x Series power supplies of the same output voltage and current rating can be
paralleled in master-slave configuration with automatic current sharing to increase available power.
1.2.8 Output Connections
Output connections are made to rear panel bus-bars. Either the positive or negative terminal
may be grounded or the output may be floated. The power supplies shall not float outputs more
than +/- 100VDC above / below chassis ground. Contact factory for assistance with higher float
voltage applications.
Local or remote sense may be used. In remote sense, the voltage drop on the load wires should
be minimized. Refer to the specifications for the maximum voltage drop value.
1.2.9 Cooling and Mechanical Construction
The RMX-410x Series is cooled by an internal fan. At installation, care must be taken to allow
free air flow into the power supply via the front panel, and out of the power supply via the rear
panel.The RMX-410x Series power supply is a compact and lightweight unit which allows for easy
installation and gives a space saving solution for customer applications.
