Safety instructions and installation requirements for the PS1111-2402-0002 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.

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 supply immediately and return the device to the factory for inspection.
  • Install the device in a housing that provides protection against electrical, mechanical and fire hazards.
  • Mount the device on a DIN rail so that the input terminals are at the bottom of the device
  • 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 leaking liquids.
  • The device insulation is designed to withstand surge voltages of overvoltage category III according to IEC 60664-1.
  • The device is designed to meet the requirements of protection class II according to IEC 61140.
  • 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 300Vac.
  • 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)!
  • The device is designed for altitudes up to 5000m (16400ft). Above 2000m (6560ft) the overvoltage category is reduced to level II, and a reduction of the output current is required.
  • Observe the following minimum installation distances: 40 mm at the top, 20 mm at the bottom, 0 mm on the left and right. Increase the 0 mm distance to 15 mm if the adjacent device is a heat source.
  • The device is designed, tested and approved for junction circuits up to 20A without an additional protective device. If an external fuse is used, do not use circuit breakers with lower characteristic than 6A B or 4A C in order 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%.
