5.2 Cable connection in inverter
versions with wiring box
To connect the signal cables to the accessory
board is necessary to:
- Remove both front covers (wiring box
(05)
and
inverter compartment
(04)
)
-
Insert the appropriate water-tight conduit
connector on signal conduit opening
(15)
and
tighten to the chassis to maintain NEMA 4X
compliance.
Conduit must be sealed using water-tight
fittings to maintain NEMA Type 4X enclosure
integrity.

ATTENTION –
A
The communication
cable (ethernet and/or RS485) must
be wrapped around the EMI ferrite
(08)
supplied in the package (1 winding); such a
EMI ferrite should be appropriately placed
on the inside bottom side of the inverter
compartment (see side illustration and
ethernet/RS485 connection paragraph in
this guide).
ATTENTION –
A
The connection of the
communication and control signal cables
should be done with no over-length of
the above mentioned cables (as in the
illustration). i.e. the cables should be
run over the internal protective sheet.
Moreover the communication and control
signal connection cables should not be in
contact witn AC cables.
