Connections to the communication and control board
Each cable which must be connected to the communication and control
board must pass through one of the three service cable glands.
• An M20 that takes cables from 7 mm to 13 mm in diameter. Gaskets
with two holes are supplied as standard to insert into the cable gland,
which enables two separate cables of a maximum cross-section of 5 mm
to be accommodated
• Two M25 that take cables from 10 mm to 17 mm in diameter. Gaskets
with two holes are supplied as standard to insert into the cable gland,
which enables two separate cables of a maximum cross-section of 6 mm
to be accommodated
Remote control connection
The connection and disconnection of the inverter to and from the grid can
be controlled through an external control.
The function must be enabled in the relevant menu. If the remote control
function is disabled, the switching on of the inverter is dictated by the
presence of the normal parameters that allow the inverter to connect to
the grid.
If the remote control function is operating, besides being dictated by the
presence of the normal parameters that allow the inverter to connect to the
grid, the switching on of the inverter also depends on the state of the R1
ON/OFF terminal compared to the RTN terminal present on the connector
29
of the communication card
06
.
When the R1 ON/OFF signal is brought to the same potential as the RTN
signal (i.e. by making a short circuit between the two terminals of the con-
nector), this causes the inverter to disconnect from the grid.
The remote control OFF condition is shown on the display.
The connections of this control are made between the “R1 ON/OFF” in-
put and “RTN”.
Since this is a digital input, there are no requirements to be observed
as regards cable cross-section (it only needs to comply with the sizing
requirement for passing cables through the cable glands and the terminal
connector).
