Quick installation guide -
ACSM1-04/04Lx
Introduction
This guide contains the very basic information
about the mechanical and electrical installation
of the ACSM1-04/04Lx drive module (55 to
160 kW). For complete documentation, see
either ACSM1-04 Drive Modules (55 to
110 kW) Hardware Manual (code:
3AFE68912130 [English]) or ACSM1-04Lx
Liquid Cooled Drive Modules (55 to 160 kW)
Hardware Manual (code: 3AUA0000022083
[English]) depending on drive type. Both are
available at www.abb.com/drives. In this guide,
the manual is referred to as the Hardware
Manual.

Safety instructions

WARNING! All electrical installation
and maintenance work on the drive
should be carried out by qualified
electricians only.
Never work on the drive, the braking chopper
circuit, the motor cable or the motor when input
power is applied to the drive. After
disconnecting input power, always wait for 5
minutes to let the intermediate circuit
capacitors discharge before you start working
on the drive, control cabling, motor or motor
cable. Even when input power is not applied to
the drive, externally supplied control circuits
may carry dangerous voltages. Always ensure
by measuring that no voltage is actually
present.
A rotating permanent magnet motor can
generate a dangerous voltage. Lock the motor
shaft mechanically before connecting a
permanent magnet motor to the drive, and
before doing any work on a drive system
connected to a permanent magnet motor.
With ACSM1-04Lx, beware of hot coolant. Do
not work on the cooling system until the
pressure is lowered down by stopping the
pumps. High-pressure hot coolant (max.
1000 kPa, 55 °C [145 PSI, 131 °F]) is present
in the cooling circuit when it is in operation.

Planning the installation

• The ACSM1-04/04Lx is an IP20 (UL open
type) drive to be used in a heated, indoor
controlled environment. The drive must be
installed in clean air according to enclosure
classification. Cooling air must be clean, free
from corrosive materials and electrically
conductive dust. See the Hardware Manual
for detailed specifications.
• The maximum ambient air temperature is
40 °C (104 °F) at rated current. The current
is derated for 41 to 55 °C (104 to 131 °F).
• The drive is suitable for use in a circuit
capable of delivering not more than 100,000
rms symmetrical amperes, 480 V maximum.
• The cables located within the motor circuit
must be rated for at least 75 °C (167 °F) in
UL-compliant installations.
• Install a hand-operated input disconnecting
device (disconnecting means) between the
AC power source and the drive. The
disconnecting device must be of a type that
can be locked to the open position for
installation and maintenance work on the
drive or the motor.
• The input cable must be protected with fuses
or circuit breakers. Suitable IEC (class gG)
and UL (class T) fuses are listed in the
Technical data section of the Hardware
Manual. For suitable circuit breakers, contact
your local ABB representative.
• For installation in the United States, branch
circuit protection must be provided in
accordance with the National Electrical Code
(NEC) and any applicable local codes. To
fulfill this requirement, use the UL classified
fuses.
• For installation in Canada, branch circuit
protection must be provided in accordance
