ACQ550-CC Packaged Drive with Bypass 1
Safety
Safety
WARNING! The ACQ550 adjustable speed AC drive with Bypass 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
ACQ550, 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 ACQ550 will start up automatically after an input voltage
interruption if the external run command is on.
WARNING! When the ACQ550 with Bypass 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 ACQ550 with Bypass 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.

Application
This manual is a supplement to the ACQ550-U1 User’s Manual and documents
Bypass configurations.
Bypass Features and Functions
The ACQ550 with Bypass is an ACQ550 AC adjustable frequency drive in an
integrated UL Type/NEMA 1, UL Type/NEMA 12, or UL Type/NEMA 3R package
with a bypass function configured entirely of standard industrial control components.
The ACQ550 with Bypass provides:
• Main circuit breaker with door mounted control lever. The lever can be padlocked
in the OFF position (padlock not supplied).
• Electrically interlocked Bypass and drive output contactors
• Class 20 motor overload protection.
• ACQ-CP-AQ drive control panel
– Cover mounted - UL Type/NEMA 1 and 12 enclosures
– Drive mounted - UL Type/NEMA 3R enclosures
• Bypass cover mounted control
