Safety instructions and installation requirements for the PS1061-2420-0000 power supply
DANGER
Danger of electric shock, fire, injuries, injuries resulting in death!
• Do not use the power supply without proper grounding (protective conductor). Use the terminal at the in-
put 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.
• If this device is operated outside of the specification, the protection offered by the device may be nega-
tively affected
Further notes on installation requirements
• If any damage or malfunction occurs during installation or operation, turn off the power supply
immediately and return the device to the factory for inspection.
• Mount the device on a DIN rail so that the input terminals are at the bottom of the device.
• Install the device in a housing that provides protection against electrical, mechanical and fire
hazards.
• Make sure that the wiring is correct by complying with all local and national regulations.
ðUse suitable copper cables designed for a minimum operating temperature of
60°C at ambient temperatures up to +45°C,
75°C at ambient temperatures up to +55°C and
90°C at ambient temperatures up to +70°C.
ðMake sure that all individual strands of a wire are inside the terminal connection.
ðUnused screw terminals should be tightened firmly.
• The maximum temperature of the ambient air is +70°C. The operating temperature corresponds
to the ambient air temperature and is defined 2cm below the device.
• This device is designed for convection cooling and does not require an external fan. Do not ob-
struct the air circulation. The ventilation grille must not be covered (e.g. by cable ducts)!
• Maintain the following installation distances:
ð40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.
ðIncrease this distance to 15mm if the adjacent device is a heat source (e.g., another power
supply).
ðThe distance can be reduced from 5mm to zero if the device is permanently loaded with
less than 50%.
• The device is designed, tested and approved for branch circuits up to 20A without an additional
protective device.
Use an additional protective device for branch circuits with larger current values. If an external in-
put protection device is used, do not use one smaller than a 10A B or 6A C characteristic in or-
der to avoid incorrect triggering of the circuit breaker.
• The device is designed as equipment of "Protection Class I" according to IEC61140.
ðDo not use the device without a proper PE (Protective Earth) connection!

Further notes on operation
• This device contains no parts that require maintenance. If an internal fuse trips, this is due to an
internal defect.
• The device is designed for areas with a degree of pollution 2 in controlled environments. No con-
densation or frost is allowed.
• The device housing offers IP20 protection. The housing offers no protection against spilled liq-
uids.
• The device is designed for operation in the relative humidity range between 5% and 95%.
• The device is designed for overvoltage category II zones. Below an altitude of 2000m the device
is tested for surge voltages up to 4kV, which corresponds to the OVCIII according to
IEC60664-1.
• The device is suitable for supply from TN, TT or IT networks. The continuous voltage between
the input terminal and the PE potential must not exceed 300Vac.
• The device is designed for altitudes up to 5000m. A reduction of the output current is required
above 2000m.

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 This document uses the term “earth” which is the same as the U.S. term “ground”.
T.b.d. Still to be defined, value or description will follow in due course.
AC 230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 230V ±10%). 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).
230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.
