Safety instructions and installation requirements for PS2031-2410-0000 power supply unit
DANGER
Danger of electric shock, fire, injuries, injuries resulting in death!
• Do not use the power supply without proper earthing (protective conductor). Use the terminal at the input
terminal strip for the earth connection, not one of the screws on the housing.
• Switch off the power supply before working on the device. Provide protection against unintentional re-
connection.
• Ensure proper wiring by following all local and national regulations.
• Do not modify or attempt to repair the device.
• Do not open the device, as high voltages are present inside.
• Avoid foreign bodies entering the housing.
• Do not use the device in damp locations or in areas where moisture or condensation is likely to occur.
• Do not touch the device when it is switched on or immediately after it has been switched off. Hot sur-
faces can cause burns.

Foreword
PS2031-2410-0000 9Version: 1.0
Further notes on installation requirements
• This device contains no serviceable parts. In the event of damage or malfunction during installa-
tion or operation, switch off the device immediately and return it to the factory for inspection. Trig-
gering of an internal fuse indicates an internal defect.
• Install the device in a housing that provides protection against electrical, mechanical and fire
hazards.
• Install the device on a DIN rail according to EN 60715, with the input terminals at the bottom of
the device. Other mounting positions require a reduction of the output current.
• Make sure that the wiring is correct. Make sure that all individual wires of a strand enter the ter-
minal connection.
• Unused screw terminals should be tightened firmly.
• The device is designed for areas with contamination level 2 in controlled environments. No con-
densation or frost is allowed.
• The device housing offers IP20 protection.
• The device insulation is designed to withstand surge voltages of overvoltage category III accord-
ing to IEC 60664-1. For delta protective conductor systems, the overvoltage category is reduced
to level II.
• The device is designed to meet the requirements of protection class I according to IEC 61140.
• Do not use the device without a proper PE connection (protective earth).
• The device is suitable for supply from TN, TT and IT networks. The voltage between the L or N
terminal and the PE terminal must not exceed 500Vac continuously.
• An isolating device must be provided for the device input.
• This device is designed for convection cooling and does not require an external fan. Do not ob-
struct the air circulation.
• The device is designed for altitudes up to 6000m (19685ft). Above 2000m (6560ft) a reduction of
the output current and overvoltage category is required.
• Maintain the following installation distances: 40mm at the top, 20mm at the bottom and 5mm
on the left and right are recommended if the device continuously runs at more than 50% of the
rated output. Increase this distance to 15mm if the adjacent device is a heat source (e.g. an-
other power supply unit). If the device continuously runs at less than 50%, the 5mm distance
can be reduced to zero.
• The device is designed, tested and approved for branch-circuit currents up to 32A (IEC) and
30A (UL) without additional protection. If an external fuse is used, do not use circuit breakers
smaller than 6A (B or C characteristic) to avoid unwanted tripping of the circuit breaker.
• The maximum ambient air temperature is +70°C (+158°F). The operating temperature corre-
sponds to the ambient or ambient air temperature, per definition at 2 cm below the device.
• The device is designed for operation in the relative humidity range between 5% and 95%.

2.3 Terminology and abbreviations
PE and the earthing
symbol
PE is the abbreviation for "protective earth" and has the same meaning as the
earthing symbol
Earth, ground The terms earth and ground are synonymous and are used interchangeably in this
document.
T.b.d. Still to be defined, value or description will follow in due course.
AC 400V A value preceded by "AC" or "DC" represents a nominal voltage or a nominal
voltage range. The nominal voltage or the nominal voltage range may be provided
with tolerances. (e.g., AC380 - 480V ±15%). The calculated total range then
indicates the working range of the device.
Example:
DC 12V refers to a 12V battery, regardless of whether it is fully charged
(13.7Vdc) or discharged (10Vdc).
400Vac A value followed by the unit Vac or Vdc is an instantaneous value that does not
contain any additional tolerances.
50Hz vs. 60Hz Unless otherwise specified, AC 230V parameters are valid at a mains frequency of
50Hz.

3.7 Lifetime expectancy
The lifetime expectancy shown in the table indicates the minimum number of operating hours (service life)
and is determined by the lifetime expectancy of the built-in electrolytic capacitors. The lifetime expectancy is
stated in operating hours and is calculated according to the specifications of the capacitor manufacturer. The
manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years (131,400h). Any
number exceeding this value represents a calculated theoretical lifetime which can be used to compare
devices.

3.8 MTBF
MTBF stands for Mean Time Between Failure, which is calculated from the statistical failure rate of the
components and indicates the reliability of a device. It is a statistical representation of the probability of
equipment failure and does not necessarily represent the service life of a product.
The MTBF number is a statistical representation of the probability of equipment failure. An MTBF number of
1,000,000h, for example, means that statistically, if there are 10,000 devices in use, one device will fail every
100 hours. However, it is not possible to say whether the failed device has been in operation for 50,000
hours or only 100 hours.
For these device types the MTTF value (Mean Time To Failure) is identical to the MTBF value.

Wiring instructions:
• Use suitable copper cables that are designed for at least the following operating temperatures: +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.
• Observe the national installation rules and regulations!
• Make sure that all single wires of a strand are connected to the terminal!
• Unused terminals should be tightened firmly.
• Ferrules are permitted.
Series connection of power supply units:
Series connection (looping from one power supply output to the next) is permitted as long as the average
output current flowing through a connection pin does not exceed 25A. For higher currents please use a
separate distributor terminal strip as shown in Fig. Using distribution terminals.
