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.
