Wiring diagram and dimensions
Installation and operating
The relay is installed in a plastic or metal box on a standard DIN-rail width 35 mm with latches having two fixed positions.
The protection settings are set using the adjustments on the front panel of the device. During operation, the LEDs signal the operation or operation of the relay protection (see Fig.3.). The lower switch can not be set as shown in Fig.4
