Safety instructions and installation requirements for PS2001-4810-0000 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 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.

WARNING

Explosion hazard warning!

Do not use with DC input voltages.
Do not use with AC input voltages below 90Vac.
Use only in standard vertical mounting orientation with the input terminals at the bottom of the device.
Replacement of components may affect the suitability for this environment.
Do not disconnect the device from the mains and do not operate the voltage adjustment unless the power is switched off or the environment can be considered safe.
For the end product a suitable housing must be provided, which has a minimum protection class of IP54 and meets the requirements of EN 60079-0.

Notice

Further notes on installation requirements

  • This device contains no parts that require maintenance. If an internal fuse trips, this is due to an internal defect.
  • If any damage or malfunction occurs during installation or operation, turn off the power immediately and return the device to the factory for inspection.
  • 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 terminal connection.
  • Unused screw terminals should be tightened firmly.
  • The device is designed for areas with contamination level 2 in controlled environments. No condensation or frost is allowed.
  • The device housing offers IP20 protection.
  • The device insulation is designed to withstand pulse voltages of overvoltage category III according to IEC 60664-1.
  • 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). For the earth connection use the terminal on the input block, not one of the screws on the housing.
  • 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 300Vac continuously.
  • The input can also be powered from batteries or similar DC power sources. The voltage between the input terminal and the PE terminal must not exceed 375Vdc 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 obstruct the air circulation. No more than 15% of the ventilation grille may be covered (e.g. by cable ducts)!
  • 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. another 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 10A (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 corresponds 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%.
