Cabling should be 300V rated. Rated for at least 3A continuous in line
with local wiring regulations. Cabling should be protected 3A non time
delay fuses i.e. gG, Class CC or Class J and rated for at least 300V, in
accordance with local wiring regulations.

Key:
Destination Indicates the parameter which is being controlled by the
parameter: terminal / function
Source
Indicates the parameter being output by the terminal
parameter:
Mode Analog - indicates the mode of operation of the terminal,
parameter: i.e. voltage 0-10V, current 4-20mA etc.
Digital - indicates the mode of operation of the terminal,
i.e. positive / negative logic, open collector.
All analog terminal functions can be programmed in menu 7.
All digital terminal functions (including the relays) can be programmed in
menu 8.
The setting of Pr 6.04 can cause the function of digital inputs T25 to T27
to change. For more information, refer to section 11.22.5 Start / stop
logic modes on page 143.
If the control circuits are to be connected to other circuits
classified as Safety Extra Low Voltage (SELV) (e.g. to a
personal computer), an additional isolating barrier must be
included in order to maintain the SELV classification.
WARNING
If any of the digital inputs (including the drive enable input)
are connected in parallel with an inductive load (i.e.
contactor or motor brake) then suitable suppression (i.e.
diode or varistor) should be used on the coil of the load. If no
CAUTION suppression is used then over voltage spikes can cause
damage to the digital inputs on the drive.

The control circuits are isolated from the power circuits in the
drive by basic insulation (single insulation) only. The installer
must ensure that the external control circuits are insulated
from human contact by at least one layer of insulation
(supplementary insulation) rated for use at the AC supply
