NOTE:
Cables for sensors, DI inputs and data communication must be kept separate from other high voltage cables to
avoid electric noises.
◦ Use separate cable trays
◦ Keep a distance between cables of at least 10 cm
◦ Long cables at the DI input should be avoided
Do not use excessive force while securing wires in to the connectors, allowed tightening torque and wire sizes
are:
◦ Power connectors: wire size = 0.5 – 1.5 mm
2
, max. tightening torque = 0.4 Nm
◦ Low voltage signal connectors: wire size = 0.15 – 1.5 mm
2
, max. tightening torque = 0.2 Nm
◦ 2L and 3L must be connected to the same phase

DI1
12,13
Digital input signal
The dened function is active when the input is short-circuited or opened, depending on the function dened in o02.
Note: DI1 can also be used for a Sc Condenser sensor
DI2
13,14
Digital input signal
The dened function is active when the input is short-circuited or opened, depending on the function dened in o37.
