Installation and Connection
Binary Output Relays, System Contact and IRIG
The number of the binary output relay contacts is related to the type of the device or type code. The binary
output relays are potential-free change-over contacts. In chapter [Assignment/binary outputs] the assignment of
the binary output relays is specified. The changeable signals are listed in the »assignment list« which can be
found in the appendix.
Make sure that the tightening torque is 0.56-0.79 Nm [5-7 In-lb].
Please duly consider the current carrying capacity of the binary output
relays. Please refer to the Technical Data.
The system contact closes after the boot phase of the device if the protection is working.
This contact will open if an internal device error has occurred (please refer to chapter Self Supervision).
