ESCRIPTION
The QS5.DNET power supply is a derivate of the
Dimension QS5 family, which is specially designed to
meet the DeviceNet
®
requirement. The QS5.DNET exists
beside the QS10.DNET, which is the right choice to
supply networks with the thick cables.
The specialties of DeviceNet
®
power supplies are:
The nominal and overload currents are sized for the
ratings of the DeviceNet
®
cables.
Large load capacitors can be charged in a very short
period of time.
After turn on, the output voltage increases according
to the DeviceNet
®
timing specification.
The upper level of the output level is limited to
protect the network.
The most outstanding features are a high efficiency,
compact size, wide-range input voltage, a very low
inrush surge and a DC-ok contact. High immunity to
transients and power surges and a low electromagnetic
emission makes usage in nearly every environment
possible.
Unique quick-connect spring-clamp terminals allow a
safe and fast installation. A large international approval
package makes this unit suitable for nearly every
situation.

This document uses the term “earth” which is the same as the U.S. term “ground”.
To be defined, value or description will follow later.
A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±15%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.
As long as not otherwise stated, AC 230V parameters are valid at 50Hz mains frequency.

SE
This device is designed for installation in an enclosure and is intended for the general use such as in industrial control,
office, communication, and instrumentation equipment.
Do not use this power supply in aircraft, trains, nuclear equipment or similar systems where malfunction may cause
severe personal injury or threaten human life.
This device is designed for use in hazardous, non-hazardous, ordinary or unclassified locations.
2. I
NSTALLATION
R
EQUIREMENTS
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to
the factory for inspection.
Mount the unit on a DIN-rail so that the output terminals are located on the top and input terminals are located on
the bottom of the unit. For other mounting orientations see de-rating requirements in this document. See chapter
24.12.
This device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do
not cover ventilation grid (e.g. cable conduits) by more than 30%!
Keep the following installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right sides are
recommended when the device is loaded permanently with more than 50% of the rated power. Increase this clearance
to 15mm in case the adjacent device is a heat source (e.g. another power supply).
WARNING
Risk of electrical shock, fire, personal injury or death.
- Do not use the power supply without proper grounding (Protective Earth). Use the terminal on the input block for
earth connection and not one of the screws on the housing.
- Turn power off before working on the device. Protect against inadvertent re-powering.
- Make sure that the wiring is correct by following all local and national codes.
- Do not modify or repair the unit.
- Do not open the unit as high voltages are present inside.
- Use caution to prevent any foreign objects from entering the housing.
- Do not use in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.
