N O T I C E
If the AC drive is supplied with external 24 V DC power, use a diode in terminal #6 (or #12) to prevent the current to flow in
opposite direction. Put a 1 A fuse in 24 V DC line for each AC drive. The maximum current consumption of each drive is 1 A from
the external supply.

N O T I C E
The control unit I/O ground is not isolated from the chassis ground/protective earth. In the installation, consider the potential
differences between the grounding points. We recommend using galvanic isolation in the I/O and 24 V circuitry.
7.3 Control Unit Cabling
7.3.1 Selection of the Control Cables
The control cables must be a minimum of 0.5 mm
2
(20 AWG) shielded multicore cables. See more on the cable types in Table 16. The
terminal wires must be a maximum of 2.5 mm
2
(14 AWG) for the terminals of the relay board and 1.5 mm
2
(16 AWG) for other termi-
nals.
NOTE! The drive option with the integrated control unit does not require connecting of cables by the customer except for frame
FR12.
