Safety instructions and installation requirements for the PS1021-2405-0000 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.
• Mount the device on a DIN rail so that the input terminals are at the bottom of the device. For
other mounting positions, please refer to the load reduction requirements in this document. See
chapter Installation positions.
• This device is designed for convection cooling and does not require an external fan. Do not ob-
struct the air circulation. No more than 15% of the ventilation grille may be covered (e.g. by cable
ducts)!
• 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).
