MicroFlex e190
Introduction
This guide contains the very basic information
about the mechanical and electrical installation
of the MicroFlex e190 drive module. For
complete documentation see the
MicroFlex e190 User’s Manual (code:
3AXD50000037326 [English]).
Safety instructions
WARNING! All electrical
installation and maintenance work on
the drive should be carried out by
qualified electricians only.
WARNING! Operation of this
equipment requires detailed
installation and operation instructions
provided in the Installation/Operation
manual intended for use with this product. It
should be retained with this device at all times.
A hard copy of this information may be ordered
at +358 10 22 11 or your local ABB sales office.
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.
• The MicroFlex e190 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 User’s Manual for
detailed specifications.
• The MicroFlex e190 must be installed where
the pollution degree according to UL and EN
61800-5-1 shall not exceed 2.
• The maximum ambient air temperature is:
1.6 A model
: 45 °C (113 °F) at rated current.
The current is derated for 45 to 50 °C (113 to
122 °F). See user’s manual.
3 A - 9 A models
: 55 °C (131 °F) at rated
current. No current derating is required.
• Motor overtemperature sensing is not
provided by the drive.
• The drive is suitable for use in a circuit
capable of delivering not more than 5,000
rms symmetrical amperes, 240 V maximum,
when protected by CC class fuses, rated
max. 20 A.
• The cables located within the motor circuit
must be rated for at least 75 °C (167 °F) in
UL-compliant installations.
• Use 75 °C copper wiring only.
• The input cable must be protected with
fuses. Suitable IEC (class gG) and UL (class
CC) fuses are listed in the Technical data
section of the MicroFlex e190 User’s
Manual.
• Integral solid state short circuit protection
does not provide branch circuit protection.
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.
