Safety

WARNING! The ACH550 adjustable speed AC drive with Input Disconnect

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 and U2, V2, W2 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 removed 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 drive units 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 units or an

external supply.

WARNING! The ACH550 will start up automatically after an input voltage

interruption if the external run command is on.

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.

Note! For more technical information, contact the factory or your local ABB sales

representative.

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:

Dangerous voltage warning warns of high voltage which can cause physical

injury and/or damage to the equipment.

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 1.

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), 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).

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 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.
