In this way the various slaves in the SmartWire-DTsystem will not be electrically isolated from one another. Thefield bus and the SmartWire-DT system are electricallyisolated from one another.j Danger!The gateway has protection against polarity reversal forthe 24-V-DC-POW supply. However, if the gateway isconnected via the serial interface to an earthed device (forexample to a PC), the gateway can be destroyed, if thepolarity of the power supply is reversed!
