Safety instructions and installation requirements for the PS1011-2420-0000 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.
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.
• Install the device on a DIN rail according to EN 60715, with the input terminals at the bottom of
the device.
• 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 leaking liq-
uids.
• The device insulation is designed to withstand surge voltages of overvoltage category III accord-
ing 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).
• 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.
• A disconnector 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 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 overvolt-
age 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, 5
mm on the left and right. Increase the 5 mm distance to 15 mm if the adjacent device is a heat
source. 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 junction circuits up to 20A without an additional
protective device. For higher junction circuits an additional protective device must be used. If an
external input protection device is used, do not use a device with a lower characteristic than 10A
B or 6A C in order to prevent unwanted circuit breaker tripping.
• 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%.
