Supply voltage for device

Requirements:

}

When selecting the power supply, please refer to the requirements stated under “Tech­
nical Details”.

Make sure that the supply voltage for the power circuits (B1/B2) complies with the spe­
cified tolerance of +/­10 %. If the voltage is outside this tolerance, then

–

the device will change to a fault condition, if the outputs are switched on

–

a message will be entered in the error stack if the outputs are switched off.

}

The power supply must be able to bridge a power outage of 20 ms.

WARNING!

Electric shock!

Safe electrical isolation must be ensured for the external power supply that
generates the supply voltage. Failure to do so could result in electric shock.
The power supplies must comply with EN 60950­1, 05/2006, EN 61558­2­6,
11/1997.

Supply voltage to the device

Please note: The supply
voltage must be protected
with a fuse.
