Safety instructions and installation requirements for the PS1021-2405-0000 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 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 reconnection.
  • 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 surfaces can cause burns.
  • If this device is operated outside the specification, the protection provided by the device may be negatively 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.
  • 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 obstruct the air circulation. The ventilation grille must not be covered (e.g. by cable ducts)!
  • Maintain the following installation distances:
  • 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 input protection device is used, do not use one smaller than a 10 A B or 6 A C characteristic in order to avoid incorrect triggering of the circuit breaker.
  • Do not use this device on AC 200 V mains supplies with loads greater than 4.5 A if the application is sensitive to short drops in output voltage during power cuts, even if they are shorter than 20 ms.
  • The device is designed as equipment of "Protection Class I" according to IEC 61140.
Safety instructions 3:

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 condensation or frost is allowed.
  • The device housing offers IP20 protection. The housing offers no protection against spilled liquids.
  • 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.
