6 - Connect the keypad to the inverter using the wire supplied. On the keypad side, the wire is provided with a
telephone connector and a loop lug connected to the wire screening braiding. Fasten the loop to the panel
grounding using one of the mounting jig fastening screws. Tighten the screw in an uncoated area of the panel,
to ensure it is electrically connected to the ground. Panel grounding must comply with the safety regulations in
force.
7 – Fit the display/keypad to its housing (side tabs snap); make sure that the telephone connector is connected
both to the keypad and to the inverter. Avoid stretching the keypad wire.
The remoting kit ensures degree of protection IP54 for the front panel.

CAUTION
Never connect and disconnect the keypad when the inverter is on. Temporary
overload may lock the inverter due to alarm trip.
CAUTION
Only use wires supplied by Elettronica Santerno for the keypad wiring. Wires with a
different contactor arrangement will cause irreparable damages to the inverter and
the display/keypad. A remoting wire with different specifications may cause
disturbance and affect communications between the inverter and the
display/keypad.
CAUTION
Properly connect the remoting wire by grounding its braiding as explained above.
The remoting wire must not be parallel-connected to the power wires connecting the
motor or feeding the inverter.
This will reduce disturbance between the inverter and the display/keypad connection
to a minimum.
