Transition Networks SISTF10xx-141-LR(T) Connecting power to the Industrial Switch

Transition Networks SISTF10xx-141-LR(T) Industrial Unmanaged Switch

Connecting power to the Industrial Switch

Redundant	The Industrial Switch has dual (redundant) power inputs capable of auto-sensing the input
power inputs	voltage, while providing over current protection and reverse polarity protection.

The dual power inputs can be connected simultaneously to live DC power sources. See Figure

8.If one power source fails, the other live source acts as a backup, and automatically supplies the Industrial Switch with power.

IMPORTANT

•Power is supplied through an external 12-48 VDC power source. Check the Technical Specification section for details about the DC power input voltage.

•The Industrial Switch does not include a power switch; therefore, plugging a wired and active terminal-block plug into its terminal block will immediately power ON the unit.

CAUTION

Before connecting the Industrial Switch to a DC power source, ensure the power source is stable.

CAUTION

This device is intended to be supplied by a listed power source marked LPS or Limited

Power Source, provided with a connector for field wiring terminal.

CAUTION

This device is designed for operation with a safety extra-low voltage (SELV) in compliance with IEC950 / EN60950 / VDE0805 and in compliance with the low voltage directive 73/23/EEC and 93/68/EEC.
