Local parameterization
When the parameters are set locally, the setting parameters can be chosen via the
hierarchical menu structure. The wanted language can be selected for parameter
descriptions. Refer to the Operator
’
s Manual for further information.
External parameterization
Relay Setting Tool is used for parameterizing the relay units. Adjusting the
parameter values using Relay Setting Tool is done off-line, after which the
parameters can be downloaded to the relay via a communication port.

Design description
5.2.1.
Input/output connections
All external circuits are connected to the terminals on the rear panel of the relay.
*
Terminals X2.1-_ are dimensioned for one 0.5...6.0 mm
2
(AWG 20-8) wire or
two max 2.5 mm
2
(AWG 24-12) wires
*
Terminals X3.1-_ and X4.1-_ are dimensioned for one 0.2...2.5 mm
2
wire or two
0.2...1.0 mm
2
(AWG 24-16) wires.
The energizing phase currents of the relay are connected to terminals:
*
X2.1/1-2
*
X2.1/3-4
*
X2.1/5-6
For inputs for ground-fault currents, refer to Table 5.2.1.-1.
The relay can also be used in single or two-phase applications by
leaving one or two energizing inputs unoccupied. However, at least
terminals X2.1/1-2 must be connected.
The energizing of the relay is connected to terminals X2.1/7-8, see Table 5.2.1.-1.
The input terminals of the optional RTD module are located on connection socket
X3.1. The RTD sensors or thermistors are connected to terminals X3.1/7-24, see
Table 5.2.1.-6. Both the inner and the outer shield of the cable must be connected to
the chassis ground screw between connectors X4.1 and X3.1 (lower screw). In
addition, the outer shield must be connected to chassis ground at the other end of the
cable as well.
When connection socket X3.1 is used, the RTD module must be
installed.
