As you install the wiring, observe the following:
• For the power connection points on the drive see the "Connection Diagrams"
section below.
• Use separate conduit runs to keep these three classes of wiring apart:
– Input power wiring.
– Motor wiring.
– Control/communications wiring.
• For details on power connections, refer to the following sections in "Technical
Data":
– "Input Power Connections" on page 225.
– "Motor Connections" on page 229.
• For floating networks (also known as IT, ungrounded, or high impedance
networks):
– Disconnect the internal RFI filter by removing both the EM1 and EM3 screws
(frame sizes R1…R4, see page 10), or F1 and F2 screws (frame sizes
R5…R6, see page 11).
– Do NOT install an external filter, such as one of the kits listed in the filter table
on 233. Using an EMC/RFI filter grounds the input power through the filter
capacitors, which could be dangerous and could damage the unit.
– Where EMC requirements exist, check for excessive emission propagated to
neighboring low voltage networks. In some cases, the natural suppression in
transformers and cables is sufficient. If in doubt, use a supply transformer with
static screening between the primary and secondary windings.
• For details on control connections, refer to the following sections:
– "Control Connections" on page 234.
– "Application Macros" starting on page 30.
• For electro-magnetic compliance (EMC), follow local codes and the requirements
in "Motor Cable Requirements for CE & C-Tick Compliance" on page 231. For
example:
– Properly ground the wire screen cable shields.
– Keep individual un-screened wires between the cable clamps and the screw
terminals as short as possible.
– Route control cables away from power cables.
