Further notes on installation requirements
• This device contains no serviceable parts. In the event of damage or malfunction during installa-
tion or operation, switch off the device immediately and return it to the factory for inspection. Trig-
gering of an internal fuse indicates an internal defect.
• 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. 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 ter-
minal connection.
• Unused screw terminals should be tightened firmly.
• The device is designed for areas with contamination level 2 in controlled environments. No con-
densation or frost is allowed.
• The device housing offers IP20 protection.
• The device insulation is designed to withstand surge voltages of overvoltage category III accord-
ing to IEC 60664-1. For delta protective conductor systems, the overvoltage category is reduced
to level II.
• 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 and IT networks. The voltage between the L or N
terminal and the PE terminal must not exceed 500Vac 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 ob-
struct the air circulation.
• 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. an-
other 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 6A (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 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%.
