• Mounting hardware: screws or nuts and bolts, four each. The type of hardware
depends on the mounting surface and the frame size:
Suitable Environment and Enclosure
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 244.
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.
Suitable Mounting Location
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 243), plus air flow space around the unit (see
"Cooling" on page 240).
• The distance between the motor and the drive is limited by the maximum motor
cable length. See either "Motor Connection Specifications" on page 232, or
"EN61800-3 Compliant Motor Cables" on page 235.

Wiring Overview
Warning! Ensure the motor is compatible for use with the AYK550. The AYK550
must be installed by a competent person in accordance with the
considerations defined in "Preparing for Installation" on page 4. If in doubt,
contact your local YORK sales or service office.
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 228.
– "Motor Connections" on page 232.
• 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 236. 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 237.
– "Application Macros" starting on page 35.
• For electro-magnetic compliance (EMC), follow local codes and the requirements
in "Motor Cable Requirements for CE & C-Tick Compliance" on page 234. 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.

Note! Before increasing motor speed, check that the motor is running in the desired
direction.To change rotation direction, switch motor leads as shown below.
Note! For drives with bypass, if motor is running in reverse switch incoming power
lines at input disconnect.
Start-Up
The AYK550 has default parameter settings that are sufficient for many situations.
However, review the following situations. Perform the associated procedures as
appropriate.
Spin Motor
When first installed and started the control panel displays a welcome screen with the
following options.
• Press Exit to commission the drive as described in section “Start-Up by Changing
the Parameters Individually” on page 23.
• Press Enter to move to the following options:
– Select “Commission Drive” to commission the drive as described in section
“Start-Up by Using the Start-Up Assistant” on page 23.
– Select “Spin Motor” to operate the motor prior to commissioning. This option
operates the motor without any commissioning, except entry of the motor data
as described below. Spin Motor is useful, for example, to operate ventilation
fans prior to commissioning.
Note! When using Spin Motor, the motor speed is limited to the range 1/3…2/3 of
maximum speed. Also, no interlocks are activated. Finally, once the drive is
commissioned, the welcome screen and this option no longer appear.

Motor Data
The motor data on the ratings plate may differ from the defaults in the AYK550. The
drive provides more precise control and better thermal protection if you enter the
rating plate data.
1. Gather the following from the motor ratings plate:
•Voltage
• Nominal motor current
• Nominal frequency
• Nominal speed
• Nominal power
2. Edit parameters 9905…9909 to the correct values.
• Assistant Control Panel: The Start-up Assistant walks you through this data entry
(see page 27).
• Basic Control Panel: Refer to "Parameters Mode" on page 26, for parameter
editing instructions.
Macros
Note! Selecting the appropriate macro should be part of the original system design,
since the control wiring installed depends on the macro used.
1. Review the macro descriptions in "Application Macros" on page 35. Use the macro
that best fits system needs.
2. Edit parameter 9902 to select the appropriate macro. Use either of the following:
• Use the Start-up Assistant, which displays the macro selection immediately after
motor parameter setup.
• Refer to "Parameters Mode" on page 26, for parameter editing instructions.
Tuning – Parameters
The system can benefit from one or more of the AYK550 special features, and/or fine
tuning.
1. Review the parameter descriptions in "Parameter Descriptions" starting on page 51.
Enable options and fine tune parameter values as appropriate for the system.
2. Edit parameters as appropriate.
Fault and Alarm Adjustments
The AYK550 can detect a wide variety of potential system problems. For example,
initial system operation may generate faults or alarms that indicate set-up problems.
1. Faults and alarms are reported on the control panel with a number. Note the number
reported.
2. Review the description provided for the reported fault/alarm:
