Safety
Use of warnings and notes
There are two types of safety instructions throughout this manual:
• Notes draw attention to a particular condition or fact, or give information on a
subject.
• Warnings caution you about conditions which can result in serious injury or death
and/or damage to the equipment. They also tell you how to avoid the danger. The
warning symbols are used as follows:
Electricity warning warns of hazards from electricity which can cause physical
injury and/or damage to the equipment.
General warning warns about conditions, other than those caused by electricity,
which can result in physical injury and/or damage to the equipment.
WARNING! The AYK550 adjustable speed AC drive should ONLY be installed by a
qualified electrician.
WARNING! Even when the motor is stopped, dangerous voltage is present at the
power circuit terminals U1, V1, W1 (L1, L2, L3) and U2, V2, W2 (T1, T2 T3) and,
depending on the frame size, UDC+ and UDC-, or BRK+ and BRK-.
WARNING! Dangerous voltage is present when input power is connected. After
disconnecting the supply, wait at least 5 minutes (to let the intermediate circuit
capacitors discharge) before removing the cover.
WARNING! Even when power is switched off from the input terminals of the
A<.550, there may be dangerous voltage (from external sources) on the terminals
of the relay outputs.
WARNING! When the control terminals of two or more drives are connected in
parallel, the auxiliary voltage for these control connections must be taken from a
single source which can either be one of the drives or an external supply.

Safety
WARNING! Disconnect the internal EMC filter when installing the drive on an IT
system (an ungrounded power system or a high-resistance-grounded [over 30 ohm]
power system).
WARNING! Do not attempt to install or remove EM1, EM3, F1 or F2 screws while
power is applied to the drive’s input terminals.
WARNING! Do not control the motor with the disconnecting device (disconnecting
means); instead, use the control panel keys or commands via the I/O board of the
drive. The maximum allowed number of charging cycles of the DC capacitors (i.e.
power-ups by applying power) is five in ten minutes.
WARNING! Never attempt to repair a malfunctioning AYK550; contact the factory or
your local Authorized Service Center for repair or replacement.
WARNING! The AYK550 will start up automatically after an input voltage
interruption if the external run command is on.
WARNING! The heat sink may reach a high temperature.
Note: For more technical information, contact the factory or your local JCI
representative.

Confirm that the mounting location meets the following constraints:
• R1…R6: The drive must be mounted vertically on a smooth, solid surface, and in
a suitable environment as defined above.
• The drive must be located in a suitable environment as defined above.
• The minimum space requirements for the drive are the outside dimensions (see
Outside dimensions – R1…R6 on page 1-325 or Outside dimensions – R7…R8
on page 1-326), plus air flow space around the unit (see Cooling on page 1-320).
• The distance between the motor and the drive is limited by the maximum motor
cable length. See either Motor connection specifications on page 1-311, or
EN 61800-3 compliant motor cables on page 1-314.
• The mounting site must support the drive’s weight. See Weight on page 1-324.

Wiring overview
Conduit kit
Wiring R1…R6 drives with the UL type 1 Enclosure requires a conduit kit with the
following items:
• conduit box
• screws
• cover
The kit is included with UL type 1 Enclosures.
Wiring requirements
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 1-10. If in doubt, contact your local ABB
sales or service office.
As you install the wiring, observe the following:
• There are two sets of wiring instructions – one set for each enclosure type (UL
type 1 and UL type 12). Be sure to select the appropriate procedure.
• For the power connection points on the drive see the Connection diagrams
section below.
• Use separate, metal conduit runs to keep these three classes of wiring apart:
– Input power wiring.
– Motor wiring. (Use a separate, metal conduit run for each drive)
– Control/communications wiring.
• When installing input power and motor wiring, refer to the following, as
appropriate:
• To locate input power and motor connection terminals, see Connection diagrams
starting on page 1-20. For specifications on power terminals, see Drive’s power
connection terminals on page 1-309.
• For corner grounded TN systems, see section Unsymmetrically grounded
networks on page 1-307.
• For IT systems, see section Floating networks on page 1-308.
• For frame size R6, see Power terminal considerations – R6 Frame size on page
1-309 to install the appropriate cable lugs.

• For electro-magnetic compliance (EMC), follow local codes and the requirements
in Motor cable requirements for CE & C-Tick compliance on page 1-313. 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.
