SIEMENS 6EP3333-6SC00-0AY0 Switched Mode Power Supply Unit
Description
The LOGO!Power power supply is a built-in unit, degree of protection IP20, protection class II (without protective conductor). Primary switched-mode power supply for connection to 1-phase AC line systems (TN, TT or IT system according to IEC 60364-1) with rated voltages 100 – 240 V, 50 – 60 Hz; output voltage 24 V DC, isolated, short-circuit and no-load proof.
Safety notes
Appropriate transport, proper storage, mounting, and installation, as well
as careful operation and service, are essential for the error-free, safe and
reliable operation of the device/system. Setup and operation of this
device/system are permitted only if the instructions and warnings of the
associated technical documentation are carefully observed. Only qualified
personnel are allowed to install the device/system and set it into operation.
Assembling
- Mounted on a standard mounting rail TH35-15/7,5 (EN 60715) or wall mounting with withdrawable mounting lugs.
- The device should be mounted so that the terminals are at the top.
- A clearance of at least 20 mm must be maintained above and below the device.
- If the device is to be used in a hazardous zone (II 3G Ex ec IIC T3 Gc) it must be installed in a distribution box with degree of protection IP54 or higher. This enclosure must comply with the requirements of IEC 60079-0 and must require a tool for opening.
Connecting
WARNING: Before starting any installation or maintenance work, the main system switch must be opened and measures taken to prevent it from being reclosed. If this instruction is not observed, touching live parts can result in death or serious injury.
For installation of the devices, the relevant country-specific regulations must be observed. Important note: A fuse, a miniature circuit breaker or motor circuit breaker must be provided at the input side. The supply voltage must be connected according to IEC 60364 and EN 50178. Use copper wire approved for 60/75 °C
