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.
ð
Use suitable copper cables designed for a minimum operating temperature of
60 °C at ambient temperatures up to +45 °C,
75 °C at ambient temperatures up to +55 °C and
90 °C at ambient temperatures up to +70 °C.
ð
Make sure that all individual strands of a wire are inside the terminal connection.
ð
Unused screw terminals should be tightened firmly.
• 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 ob-
struct the air circulation. The ventilation grille must not be covered (e.g. by cable ducts)!
• Maintain the following installation distances:
ð
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.
ð
Increase this distance to 15 mm if the adjacent device is a heat source (e.g., another power
supply).
ð
The distance can be reduced from 5 mm to zero if the device is permanently loaded with
less than 50 %.
• 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 in-
put protection device is used, do not use one smaller than a 16 A B or 10 A C characteristic in or-
der to avoid incorrect triggering of the circuit breaker.
• Do not use this device on AC 200 V mains supplies with loads greater than 8 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.
ð
Do not use the device without a proper PE (Protective Earth) connection!
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 con-
densation or frost is allowed.
• The device housing offers IP20 protection. The housing offers no protection against spilled liq-
uids.
• 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.
