TERMINOLOGY AND ABREVIATIONS
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.

PRELIMINARYY
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 and measurement equipment or the like.
Do not use this device in equipment where malfunction may cause severe personal injury or threaten human life.
2. INSTALLATION REQUIREMENTS
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to the factory for
inspection.
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 15%!
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).
A disconnecting means shall be provided for the output of the power supplies when used in applications according to CSA C22.2 No
107.1-01.
WARNING
Risk of electrical shock, fire, personal injury or death.
- Do not use the injector without a proper grounded power supply (Protective Earth). It is recommended to ground power supply –pole
with PE.
- 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.
- 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.

10.LIFETIME EXPECTANCY AND MTBF
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 cannot be determined if the failed unit has been
running for 50 000h or only for 100h. Please note, that MTBF values of the built in power supply are given here since these are the

Output protection
Electronically protected against overload, no-load and short-circuits. In case of a protection
event, audible noise may occur.
Output over-voltage protection
Typ. 58.5Vdc
Max. 60Vdc
In case of an internal power supply defect, a redundant circuit
limits the maximum output voltage. The output shuts down and
automatically attempts to restart.
Degree of protection
IP 20
EN/IEC 60529
Penetration protection
> 4mm
E.g. screws, small parts
Over-temperature protection
Yes
Output shut-down with automatic restart.
The temperature sensor is installed on critical components
inside the unit and turns the unit off in safety critical situations
(e.g. de-rating requirements not observed, high ambient
temperature, ventilation obstructed or the mounting
orientation de-rating is not followed). There is no correlation
between the operating temperature and turn-off temperature
since this is dependent on input voltage, load and installation
methods.

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

23.APPLICATION NOTES
23.1. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 30A (UL) and 32A (IEC). An external protection is only required if the supplying
branch has an ampacity greater than this. Check also local codes and local requirements. In some countries local regulations might
apply.
If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of the circuit
breaker. A minimum value of 6A B- or C-Characteristic breaker should be used.
23.2. OPERATION ON TWO PHASES
The power supply can also be used on two-phases of a three-phase-system. Such a phase-to-phase connection is allowed as long as the
supplying voltage is below 240V+10%.
23.3. USE IN A TIGHTLY SEALED ENCLOSURE
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. In
such situations, the inside temperature defines the ambient temperature for the power supply.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The power supply is placed in the middle of the box, no other heat producing items are inside the box
The temperature sensor inside the box is placed in the middle of the right side of the power supply with a distance of 1cm.

23.4. MOUNTING ORIENTATIONS
Mounting orientations other than all terminals on the bottom require a reduction in continuous output power or a limitation in the
maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply. Therefore,
two different derating curves for continuous operation can be found below:
Curve A1 Recommended output current.
Curve A2 Max allowed output current (results in approximately half the lifetime expectancy of A1).
