Mounting

Warning! Before installation, switch off the drive power supply.
Wait for five minutes to ensure that the capacitor bank of the drive
is discharged. Switch off all dangerous voltages connected from
external control circuits to the inputs and outputs of the drive.
Note: Before mounting the module, set the supply voltage
jumpers as described above.
FEN-31 is inserted into the option slot of the drive. See the drive
hardware manual for more information.
The module is held in place with plastic retaining clips and one
screw. The screw also provides the earthing of the cable shields
connected to the module and interconnects the GND signals of the
module and the drive.
On installation of the module, the signal and power connection to
the drive is automatically made through a 20-pin connector.
Mounting procedure:
• Insert the module carefully into the option slot until the retaining
clips lock the module into position.
• Fasten the screw (included) to the stand-off.
Note: Correct installation of the screw is essential for fulfilling the
EMC requirements and for proper operation of the module.
