RFI filter
Drive
Alternative safety ground
connection for the motor
DC bus choke
Optional motor isolator
Armour or shields must be bonded using
isolator case or a flat, wide conductor.
Maximum length of conductor: 100mm (4 in)
When dimension D >300mm (12 in), bond the
armour or shield to the back-plate. If the enclosure
construction permits, you may instead bond the
armour or shield to the enclosure at the cable entry
point. Refer to R
adiated emissions in the EMC Data
Sheet.
Bond the Drive frame to
the back-plate.
Bond the RFI filter to the
back-plate using the
mounting screws.
See signal
connections
diagrams.
Fit two ferrite rings
Part No. 3225-1004
around all control cables
that exit the enclosure.
Example connections using a
DIN-rail connector
Bond armour or shields to back-plate
using an uninsulated terminal.
Bond the DIN-rail to the back-plate.
Back-plate
Enclosure
Bond the armour or shield to
the back-plate.
If the enclosure construction
permits, you may instead
bond the armour or shield to
the enclosure at the cable
entry point.
Refer to
Radiated emissions
in the EMC Data Sheet.
Alternative location
of fuses or MCB
Do not connect
the cable shields
to the resolver or
motor.
Connect the cable shields
to the ground connection
of the Drive. Refer to the
signal connections
diagram.
Optional external braking resistor
Protect and shield the resistor with a metal grille.
Use armoured or shielded cable to connect the
braking resistor.
Alternative motor and braking resistor connections
Use these wiring techniques as appropriate for the following:
Motor connected to the Drive through a terminal block.
Wiring to optional braking resistor external to the enclosure and the resistor shielding.
