Optional arc fault protection (with
an external module)
Further the relay includes a disturbance recorder. Arc
protection is optionally available.
The relay communicates with other systems using common
protocols, such as the Modbus RTU, ModbusTCP, IEC 61850,
Ethernet / IP and DNP 3.0. An optional communication option
is required for this (see ordering code in technical description).
1.2.
User interface
The relay can be controlled in three ways:
Locally with the push-buttons on the relay front panel
Locally using a PC connected to the USB port on the front
Via remote control over the optional remote control port on
the relay rear panel.
1.3.
Operating Safety
The terminals on the rear panel of the relay may
carry dangerous voltages, even if the auxiliary
voltage is switched off. A live current transformer
secondary circuit must not be opened.
Disconnecting a live circuit may cause dangerous
voltages! Any operational measures must be carried out
according to national and local handling directives and
instructions.
Carefully read through all operation instructions before any
operational measures are carried out.
