DANGER! Risk of fatal injury!
Incorrect electrical connections can cause fatal electric shocks.
• Due to the increased discharge current in motors with more than
11 kW, it is also necessary to connect reinforced earthing acc. to
EN 50178 (see Fig. 27).

Notes
3~380 V - 3~440 V AC, (±10%), 50/60 Hz, IEC 38
Type of signal: Voltage (0–10 V, 2–10 V)
Input resistance: R ≥ 10 kΩ
i
Type of signal: Current (0-20 mA, 4-20 mA)
Input resistance: R = 500 Ω
i
Can be configured in the service menu <5.3.0.0>
Connected at the factory via the M12 threaded cable connec-
tion (Fig. 2), via (1), (2), (3) according to the sensor cable des-
ignations (1,2,3).
In2 can be used as the input for remote setpoint adjustment
in all operating modes.
Type of signal: Voltage (0–10 V, 2–10 V)
Input resistance: R ≥ 10 kΩ
i
Type of signal: Current (0-20 mA, 4-20 mA)
Input resistance: R = 500 Ω
i
Can be configured in the service menu <5.4.0.0>
For both input In1 and In2
Max. load 60 mA The voltage is short-circuit proof.
Contact load: 24 V DC/10 mA
Pump cycling can be performed using an external, potential-
free contact. One-time bridging of the two terminals will
cause external pumping to take place, if it is enabled. Bridging
a second time will cause the procedure to repeat, provided
the minimum run time is adhered to.
Can be configured in the service menu <5.1.3.2>
Contact load: 24 V DC/10 mA
Interface for dual pump function
The pump can be switched on/off via the external potential-
free contact.
In systems with a high switching frequency (> 20 on/off oper-
ations per day); switching on/off must take place via "External
off".
Can be configured in the service menu <5.1.7.0>
Contact load: 24 V DC/10 mA
Potential-free individual run signal/collective run signal
(changeover contact), operation readiness signal is available
at the SBM terminals (menus <5.1.6.0>, <5.7.6.0>).
