16. Access control

To protect the IED from unauthorized access and
to maintain information integrity, the IED is
provided with a four-level, role-based
authentication system with administrator-
programmable individual passwords for the
viewer, operator, engineer and administrator level.
The access control applies to the front-panel user
interface, the web-browser based user interface
and the PCM600 tool.

17. Inputs and outputs

Depending on the standard configuration
selected, the IED is equipped with three phase-
current inputs and one residual-current input for
non-directional earth-fault protection and current
circuit supervision, or three phase-current inputs,
one residual-current input and one residual

voltage input for directional earth-fault protection
and current circuit supervision.
The phase-current inputs are rated 1/5 A. Two
optional residual-current inputs are available, i.e.
1/5 A or 0.2/1 A. The 0.2/1 A input is normally
used in applications requiring sensitive earth-fault
protection and featuring core-balance current
transformers. The residual-voltage input covers
the rated voltages 60-210 V.
The phase-current input 1 A or 5 A, the residual-
current input 1 A or 5 A, alternatively 0.2 A or 1 A,
and the rated voltage of the residual voltage input
are selected in the IED software. In addition, the
binary input thresholds 18...176 V DC are
selected by adjusting the IED's parameter
settings.
