Safety information/installation requirements for PS9011-2420-0001 Buffer Module
DANGER
Danger of electric shock, fire, injuries, injuries resulting in death!
• Switch off the power supply before working on the device. Provide protection against unintentional re-
connection.
• 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.
• Mount the device on a DIN rail according to EN 60715 with the power terminals on the top side of
the device.
• Make sure that the wiring is correct by complying with all local and national regulations. Use suit-
able copper cables designed for a minimum operating temperature of 60 °C at ambient tempera-
tures up to +45 °C, 75 °C at ambient temperatures up to +60 °C and 90 °C at ambient tempera-
tures up to +70 °C. Make sure that all individual wires of a strand are inside the terminal connec-
tion.
• 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 insulation of the devices is designed such that it can withstand pulse voltages up to 1.5 kV in
accordance with IEC 60664-1.
• The device can be supplied from a regulated power supply or a similar DC voltage source. The
continuous voltage between the supply voltage terminals and the PE potential may not exceed
60 Vdc. Use a correspondingly dimensioned 24 V power supply unit that can supply the addi-
tional internal current consumption required to charge the capacitors. Pay attention to the correct
polarity of the supply voltage. The device does not work if the voltage polarity is reversed. The
device must be supplied from a PELV or SELV source or an "isolated secondary circuit" in order
to guarantee a SELV or PELV level.
• If the buffer module is connected to a DC source that can supply a continuous current of more
than 80 A, a 50 A or 63 A circuit breaker with a B or C characteristic must be connected between
the DC source and the buffer module.
• The device is designed for convection cooling and does not require an external fan. Do not ob-
struct the air flow or cover the ventilation grille!
• Observe the following minimum installation distances: 40 mm above, 20 mm below, 0 mm left
and right.
• The device is designed for altitudes of up to 5000 m.
• The maximum temperature of the ambient air is +70 °C (+158 °F). The operating temperature
corresponds to the ambient air temperature and is defined 2 cm below the device.
• The device is designed for operation in the relative humidity range between 5 % and 95 %.
• For EMC reasons the signal cables (ready, active, inactive) must be shorter than 30 m.
