4)
For wiring distances longer than 50 m (150 ft), it is necessary to use
galvanic isolators for the XC1:11 to
XC1
:
20 analog signals.
5)
Relays, contactors, solenoids or electromagnetic braking coils installed
near inverters can generate interference in the control circuit. In order to
eliminate this interference, connect RC suppressors in parallel with the
coils of AC relays. Connect a free - wheeling diode in case of DC relays/
coils.
6)
When an external keypad (HMI) is used (Refer to chapter 8), separate the
cablethat connects the keypad totheinverter from other cables,maintaining
a minimum distance of 10 cm (4 in) between them.
Connection 1
– Keypad Start/Stop (Local Mode)
With the
factory default setting
, you can operate the inverter in the local
mode. This operation mode is recommended for users who are operating the
inverter for the first time; without additional control connections. For start-up
according to this operation mode, follow chapter 5.

Connection 2
-
2-Wire Control Start/Stop (Remote Mode)
Valid for
factory default setting
and inverter operating in
remote mode
. For
the factory default programming, the selection of the operation mode (Local/
