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 ACH550 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
ACH550, 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

3-4 ACH550-PCR/PDR User’s Manual

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 ACH550; contact the factory or
your local Authorized Service Center for repair or replacement.

WARNING! The ACH550 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 ABB

representative.

Installation

Study these installation instructions carefully before proceeding. Failure to observe
the warnings and instructions may cause a malfunction or personal hazard.

WARNING! Before you begin read Safety on page 3-3.

WARNING! When the ACH550 with Input Disconnect is connected to the line power,

the Motor Terminals T1, T2, and T3 are live even if the motor is not running. Do not
make any connections when the ACH550 with Input Disconnect is connected to the
line. Disconnect and lock out power to the drive before servicing the drive. Failure to
disconnect power may cause serious injury or death.

Application

This manual contains supplemental information that is unique to ACH550 input
disconnect configurations (PCR or PDR). Refer to the base manual, ACH550-UH
HVAC User’s Manual (1…550 HP) on page 1-1, for all other information.

Input disconnect features and functions

The ACH550 with Input Disconnect is an ACH550 AC adjustable frequency drive
packaged with an input disconnect switch or circuit breaker, and with a door
mounted, external operating handle. The operating handle can be padlocked in the
OFF position (padlock not supplied). Enclosure options are UL Type 1, UL Type 12,
and UL Type 3R (NEMA 1, NEMA 12, and NEMA 3R).

The following is a typical power diagram.

Ratings and frame size

The charts in the Ratings section on page 1-297 of the ACH550-UH User’s Manual
manual list technical specifications, and identify the drive’s frame size.

Note: Some instructions in this document vary, depending on the drive’s frame size.
To read the Ratings table, you need the “Output current rating” entry from the Type

code (see page 3-10).

Suitable mounting location

For selecting a suitable mounting location for PCR/PDR configurations, refer to:

• The ACH550-UH User’s Manual on page 1-13, and

• The Technical data section on page 3-19 in this manual for the appropriate
information on dimensions and weights

• UL Type 3R, PX3R-1...PX3R-4 enclosures are designed to be mounted on a wall.
Mounting these 3R enclosures on an open rack system requires the use of the
supplied 3R enclosure back plates to maintain 3R integrity.

Installing the wiring (supplement to ACH550-UH User’s Manual)

WARNING!

• Metal shavings or debris in the enclosure can damage electrical equipment and
create a hazardous condition. Where parts, such as conduit plates require cutting
or drilling, first remove the part. If that is not practical, cover nearby electrical
components to protect them from all shavings or debris.

• Do not connect or disconnect input or output power wiring, or control wires, when
power is applied.

• Never connect line voltage to drive output Terminals T1, T2, and T3.

• Do not make any voltage tolerance tests (Hi Pot or Megger) on any part of the
unit. Disconnect motor wires before taking any measurements in the motor or
motor wires.

• Make sure that power factor correction capacitors are not connected between the
drive and the motor.

Wiring requirements

Refer to the Wiring requirements section on page 1-18 in the ACH550-UH User’s
Manual. The requirements apply to all ACH550 drives. In particular:

• Use separate, metal conduit runs for the following different classes of wiring:
– Input power wiring.

– Motor wiring.
– Control/communications wiring.

• Properly and individually ground the drive, the motor and cable shields.

This procedure applies to drive with disconnect configurations in UL Type / NEMA 12
hinged door wall mount enclosures. This filter is located at the bottom of the
enclosure. Use the following procedure to check and replace filters.

1. On the enclosure, remove the screw holding the filter bracket in place.

2. Slide the filter bracket forward until the hooks on the bracket clear the slots on the
enclosure base. This step allows the filter and bracket to drop free from the
enclosure.

3. Lift the filter out of the filter bracket and replace as appropriate.

4. With the filter in the filter bracket, align the hooks on the bracket with the slots in the
enclosure base, and press the hooks up into the slots.

5. Slide the filter bracket back, making sure that the hooks catch on the enclosure.

6. Replace the mounting screw. Tighten until the gasket on the bracket is about 50%
compressed.

Additional free space recommendations

In addition to the free space requirements for cooling shown in the ACH550-UH
User’s Manual (Cooling on page 1-318), allow:

• 800 mm (31.5 in) in front of UL Type/NEMA 1&12 floor mount enclosures – room
for the cabinet door to swing open.

• 305 mm (12 in) above UL Type 12/NEMA 12 floor mount enclosures – room for
fan replacement.

Degrees of protection

Available enclosures:

• UL Type 1 (NEMA 1 / IP 21) enclosure. The site must be free of airborne dust,
corrosive gases or liquids, and conductive contaminants such as condensation,
carbon dust, and metallic particles.

• UL Type 12 (NEMA 12 / IP 54) enclosure. This enclosure provides protection from
airborne dust and light sprays or splashing water from all directions.

• UL Type 3R (NEMA 3R) enclosure. This enclosure provides protection from the
ingress of water (rain, sleet, or snow). The external formation of ice does not
damage this enclosure.

13/32

Plenum Rating: ACH550 drives have been evaluated in accordance with the
requirements of UL508, meets all of the requirements for plenum rated drives, and is
“Suitable for Installation in a Compartment Handling Conditioned Air”.
