An external power supply unit can be used to supply the DA1 variable
frequency drive's control section with 24 V DC.

Terminal 7, 9
￫
The external control voltage (+24 V) should be able to handle a
load of at least 100 mA.
The residual ripple of this external control voltage must be less
than ±5 % ΔU
If the control section is powered with an external power supply unit, the
control section, the control signal terminals, and the RJ45 interface will be
active.
You will be able to do the following:
• Change parameters (but not save them)
• Read readings and error registers
• Address and read parameters via the RJ45 interface, the drivesConnect
parameter configuration program, field buses, and SmartWire-DT
• Control level functions are controlled without the power section being
powered.
• A fieldbus communication is maintained, even if there is no power
supply.
