Safety instructions and installation requirements for PS9711-2410-0000

Further notes on installation requirements

• This device may only be installed and put into operation by qualified personnel.
• If damage or malfunction should occur during installation or operation, immediately turn power off and send the device to the factory for inspection.
• Install the device onto a DIN rail according to EN 60715 with the input terminals on the bottom of the device. Other mounting orientations require a reduction in output current.
• Install device in an enclosure providing protection against electrical, mechanical and fire hazards.
• Ensure that the wiring is correct by following all local and national regulations.
• Use appropriate copper cables that are designed for a minimum operating temperature of
  70 °C for ambient temperatures up to +45 °C,
  75 °C for ambient temperatures up to +60 °C and
  90 °C for ambient temperatures up to +70 °C.
• Ensure that all strands of a stranded wire enter the terminal connection.
• Unused screw terminals should be securely tightened.
• The maximum surrounding air temperature is +70 °C. The operational temperature is the same as the ambient or surrounding air temperature and is defined 2 cm below the device.
• The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not cover ventilation grid!
• Observe the following minimum mounting distances:
• 40 mm at the top, 20 mm at the bottom and 5 mm on the left and right if the device is continuously loaded with more than 50% of its rated power
• Increase the distance from 5 mm to 15 mm if the adjacent device is a heat source (e.g., another power supply).
• When the device is permanently loaded with less than 50%, the 5 mm can be reduced to zero.
• The device is designed, tested and approved for branch circuits up to 50 A without additional protection device. If an external fuse is utilized, a circuit breaker with a minimum value of 20 A with a B or C characteristic should be implemented to avoid unwanted tripping of the circuit breaker.
• The input can also be supplied by batteries or similar DC sources. The voltage between the input terminals and ground must not exceed 60 Vdc continuously.
• The input must be powered from a PELV or SELV source or an “Isolated Secondary Circuit” in order to maintain a SELV or PELV output. If the input is supplied via the output of a power supply, the supply voltage of this power supply must not exceed 300/520 V, overvoltage category (OVC) II.
• The insulation of the devices is designed such that it can withstand pulse voltages up to 1.5 kV in accordance with IEC 60664-1. This enables supply from upstream power supplies connected to a supply network of overvoltage category II and voltages of up to 300 Vac (L to N) or 520 Vac (L to L), for example.
• Check for correct input polarity. The device does not work if the voltage polarity is reversed.
• A disconnecting means shall be provided for the input of the device.
• The device is designed as “Protection Class III” equipment according to IEC 61140.
• Do not use without a proper PE (Protective Earth) connection.

Further notes on operation

• This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect.
• The device is designed for areas with a pollution degree 2 in controlled environments. No condensation or frost allowed.
• The device housing has an IP20 protection rating. The housing does not provide protection against spilled liquids.
• The device is designed to operate in areas between 5 % and 95 % relative humidity.
• The device is designed for altitudes up to 5000 m. See additional requirements in this document for use above 2000 m.
