Follow instructions below for the proper installation of the control wiring:
Wire gauge: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
Maximum tightening torque: 0.5 N.m (4.50 lbf.in).
If necessary, use shielded cables. The correct connection of the cable shield is
showed in the figure 3.9.
Do not ground
Insulate with tape

Shield connection
Relays, contactors, solenoids or coils of electromechanical brakes installed close to
the output inverters may occasionally generate interferences in the control circuitry.
To eliminate this effect, RC suppressors (with AC power supply) or freewheel
diodes (with DC power supply) must be connected in parallel to the coils of these
devices.
The rated operating voltage of the DBW03 is configured by means of the DIP switch
S1, located on the CDB1 board. A model of line 400 V (DBW030380D3848SZ)
can be adjusted for three different voltage ranges: 380 V, 400 – 415 V, 440 – 480 V,
see table 3.3.
