106 Electrical installation
Leave the other ends of the control cable shields unconnected or ground them indirectly
via a high-frequency capacitor with a few nanofarads, eg, 3.3 nF / 630 V. The shield can
also be grounded directly at both ends if they are in the same ground line with no
significant voltage drop between the end points.
Connect the conductors to the appropriate terminals (see page
unit or optional terminal block X504.
Note: Keep any signal wire pairs twisted as close to the terminals as possible. Twisting the
wire with its return wire reduces disturbances caused by inductive coupling.

Connecting the external 230 V uninteruptible control voltage (UPS, option +G307)
