PRODUCT DESCRIPTION
The DIMENSION C-Line units are cost optimized power supplies
without compromising quality, reliability and performance. The
C-Line is part of the DIMENSION power supply family, existing
alongside the high featured Q-Line.
The CS3.241 includes all the essential basic functions but also
includes important features of small size, high efficiency, wide
temperature range and is NEC Class 2 compliant.
The wide range input makes worldwide installation and usage
very simple. Defects or system failures caused by wrongly set
switches cannot occur.
High immunity to transients and power surges as well as low
electromagnetic emission and a large international approval
package for a variety of applications makes this unit suitable for
nearly every situation.

TERMINOLOGY,ABREVIATIONS AND DEFINITIONS
PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol .
Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.
t.b.d. To be defined, value or description will follow later.
AC 230V 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)
230Vac A figure with the unit (Vac) at the end is a momentary figure without any additional tolerances included.
50Hz vs. 60Hz As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50Hz mains frequency. AC
120V parameters are valid for 60Hz mains frequency.

1. INTENDED USE
This device is designed for installation in an enclosure and is intended for commercial use, such as in industrial control, process control,
monitoring, measurement equipment or the like.
Do not use this device in equipment, where malfunctioning may cause severe personal injury or threaten human life without additional
appropriate safety devices, that are suited for the end-application.
If this device is used in a manner outside of its specification, the protection provided by the device may be impaired.
2. INSTALLATION INSTRUCTIONS
WARNING
Risk of electrical shock, fire, personal injury or death.
- Turn power off before working on the device and protect against inadvertent re-powering.
- Do not open, modify or repair the device.
- 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.
- Do not touch during power-on, and immediately after power-off. Hot surface may cause burns.
Obey the following installation instructions:
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.
Install device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN rail according to EN 60715 with the input terminals on the bottom of the device. Other mounting
orientations require a reduction in output current.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are designed for a
minimum operating temperature of 60°C for ambient temperatures up to +45°C, 75°C for ambient temperatures up to +60°C and 90°C
for ambient temperatures up to +70°C.
Ensure that all strands of a stranded wire enter the terminal connection. Use ferrules for wires on the input terminals. Unused screw
terminals should be securely tightened.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed.
The enclosure of the device provides a degree of protection of IP20.The housing does not provide protection against spilled liquids.
The device is designed for overvoltage category II zones. Below 2000m altitude the device is tested for impulse withstand voltages up to
4kV, which corresponds to OVC III according to IEC 60664-1.
The device is designed as “Class of Protection I” equipment according to IEC 61140. Do not use without a proper PE (Protective Earth)
connection.
The device is suitable to be supplied from TN, TT and IT mains networks. The continuous voltage between the input terminals and the PE
potential must not exceed 264Vac.
The input can also be powered from batteries or similar DC sources. The continuous voltage between the supply voltage and the
PE/ground potential must not exceed 375Vdc.
A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not cover ventilation
grid!
The device is designed for altitudes up to 5000m. Above 2000m a reduction in output current is required.

Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and right side. Increase the 5mm to
15mm in case the adjacent device is a heat source. When the device is permanently loaded with less than 50%, the 5mm can be reduced
to zero.
The device is designed, tested and approved for branch circuits up to 20A without additional protection device. If an external fuse is
utilized, do not use circuit breakers smaller than 10A B- or 6A C-Characteristic to avoid a nuisance tripping of the circuit breaker.
The maximum surrounding air temperature is +70°C.
The operational temperature is the same as the ambient or surrounding air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.
Installation Instructions for Hazardous Location Areas
The device is suitable for use in Class I Division 2 Groups A, B, C, D locations.
Substitution of components may impair suitability for this environment.
Do not disconnect the device or operate the voltage adjustment unless power has been switched off or the area is known to be non-
hazardous.

*) The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime expectancy of the built-in
electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the capacitor’s manufacturer specification. The
manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years (131 400h). Any number exceeding this value is a calculated
theoretical lifetime which can be used to compare devices.
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statistical
representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that statistically one unit will fail
every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit has been running for 50 000h or only for 100h.

17.DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground. Type and factory tests are conducted by the manufacturer.
Field tests may be conducted in the field using the appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s
down). Connect all input-terminals together as well as all output poles before conducting the test. When testing, set the cut-off current
settings to the value in the table below.

To fulfil the PELV requirements according to EN60204-1 § 6.4.1, we
recommend that either the + pole, the –pole or any other part of the
output circuit shall be connected to the protective earth system. This helps
to avoid situations in which a load starts unexpectedly or can not be
switched off when unnoticed earth faults occur.
