To install the AYK550 you need the following:
• Screwdrivers (as appropriate for the mounting hardware used)

• Frame Size R5 or R6: Punch for conduit mounting holes
•Mounting hardware: screws or nuts and bolts, four each. The type of hardware depends

Confirm that the site meets the environmental requirements. To prevent damage
prior to installation, store and transport the drive according to the environmental
requirements specified for storage and transportation. See "Ambient Conditions" on
page 241.
Confirm that the enclosure is appropriate, based on the site contamination level:
• IP 21 / UL type 1 enclosure. The site must be free of airborne dust, corrosive
gases or liquids, and conductive contaminants such as condensation, carbon
dust, and metallic particles.

Confirm that the mounting location meets the following constraints:
• The drive must be mounted vertically on a smooth, solid surface, and in a suitable
environment as defined above.
• The minimum space requirements for the drive are the outside dimensions (see
"Outside Dimensions" on page 241), plus air flow space around the unit (see
"Cooling" on page 237).
• The distance between the motor and the drive is limited by the maximum motor
cable length. See either "Motor Connection Specifications" on page 230, or
"EN61800-3 Compliant Motor Cables" on page 233.
• The mounting site must support the drive’s modest weight. See "Weight" on page

1. Mark the position of the mounting holes.
2. Drill holes of appropriate size.

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.

• Nominal frequency
• Nominal speed
• Nominal power
2. Edit parameters 9905…9909 to the correct values.
