Connecting the power supply

24 V safety extra-low voltage (SELV)

WARNING

•

The IE Switch X-300 is designed for operation with safety extra-low voltage (SELV).

This means that only SELV complying with IEC 60950-1 / EN60950-1 / VDE0805 can be

connected to the power supply terminals.

•

The power supply unit for the IE Switch X-300 power supply must meet NEC Class 2, as

described by the National Electrical Code(r) (ANSI/NFPA 70).

•

The power of all connected power supply units must total the equivalent of a power

source with limited power (LPS limited power source).

•

If the device is connected to a redundant power supply (two separate power supplies),

both power supplies must meet these requirements.

•

The signaling contact can be subjected to a maximum load of

100 mA (safety extra-low voltage (SELV), 24 VDC).

•

Never operate the device with AC voltage or DC voltage higher than 32 VDC.

CAUTION

Damage to the device due to overvoltage
If IE Switches X-300 are supplied over long 24 V power supply lines or networks, measures

are necessary to prevent interference by strong electromagnetic pulses on the supply lines.

These can result, for example, due to lightning or switching of large inductive loads.
One of the tests used to attest the immunity of devices of the IE Switches X-300 to

electromagnetic interference is 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 no. 918 422 or a comparable protective

element.

Germany

Connecting to the supply voltage (SELV)

●

The power supply is connected using a 4-pin plug-in terminal block.

●

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 IE Switch X-300 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.
