RS-232, RS-422, RS-485 ONVERTER PERATION ANUAL Operation safety The TR-55 device was designed and tested for operation safety along with the PN-EN 60950 3rd class standard. The device does not have an installed disconnecting system unit which should be installed outside the device. In case of a DC power supply to the device, an easily accessible disconnecting system should be installed in the fixed wiring outside the device.
