CAUTION
Damage to the device due to overvoltage
The connector of the external power supply is not protected against strong electromagnetic
pulses that can, for example, result from lightning strikes or switching large loads.
One of the tests used to attest the immunity of devices of the IE switches SCALANCE XC-200
to electromagnetic interference was the "surge immunity test" according to EN61000-4-5.
This test requires overvoltage protection for the power supply lines. A suitable device is, for
example, the Dehn Blitzductor BVT AVD 24, article number 918 422 or a comparable
protective element.
Manufacturer: DEHN+SOEHNE GmbH+Co. KG, Hans-Dehn-Str.1, Postfach 1640, D92306
Neumarkt, Germany
Operate the SCALANCE XC-200 with suitable overvoltage protection.
Note
The device can be disconnected from the power supply by pulling off the terminal block.
Information on the power supply
The "L1" and "L2" LEDs indicate the current range of the power supply, see the section
"LEDs "L1" and "L2" (Page 32)".
The power supply is connected using a 4-pin plug-in terminal block (spring-loaded terminal).
The terminal block ships with the device and can also be ordered as a spare part.
The power supply can be connected redundantly. Both inputs are isolated. There is no
distribution of load. When a redundant power supply is used, the power supply unit with
the higher output voltage supplies the device alone.
The power supply is connected over a high resistance with the enclosure to allow an
ungrounded set up. The two power inputs are non-floating.
Note the wiring rules.
