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 con ditions whic h 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.
•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.
•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.
General warning warns about
conditions, other than those caused
by electricity, which can result in
physical injury and/or damage to the
equipment.
•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.

ACH550 E-Clipse Bypass
Installation – drive
Follow the Installation instructions for the drive on page 3. Failure to observe the
warnings and instructions may cause a malfunction or personal hazard.
WARNING! Before you begin read Safety on page 2.
Installation – bypass
WARNING! When the ACH550 with E-Clip se Byp ass 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 E-Clipse 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.
1. Install wiring – bypass
WARNING!
•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.

Line input connections
Connect input power to the terminals of the disconnect switch or circuit breaker.
Connect the equipment grounding conductor to the ground lug at the top of the
enclosure. The figure below shows the connection points for Standard E-Clipse
Bypass configurations. Also see Connection diagrams – Standard E-Clipse Bypass
(wall mounted) on page 41 and Connection diagrams – Standard E-Clipse Bypass
(R8, floor mounted) on page 43.
Motor connections
Connect the motor cables to the output terminal block as shown in the figure below.
Also see Connection diagrams – St andard E-Clipse Bypass (wall mounted) on page
41 and Connection diagrams – Standard E-Clipse Bypass (R8, floor mounted) on
page 43. The motor grounding conductor can be connected to the ground lug near
the terminal block.
Note: Route cables through the cable guides on the left side of the enclosure. Use
separate conduits for input power and motor cables. Follow the guides to separate
the cables from each other.

WARNING! Check the motor and motor wiring insulation before connecting the
ACH550 to line power . Follow the procedure on page 12. Before proce eding with the
insulation resistance measurements, check that the ACH550 is disconnected from
incoming line power. Failure to disconnect li ne power could result in death or serious
injury.
Install the control wiring
Connect control wiring to terminal block X1 on the ACH550 control board and to
terminal block X2 on the E-Clipse Bypass control board. For more information on
these connections, refer to the following:
•X1 terminal block location and terminal data are defined in the ACH550-UH User’s Manual.
•X2 terminal block location is illustrated in the figures starting with Connection
diagrams – Vertical E-Clipse Bypass on page 40.
•X2 terminal data are provided in Basic control connections for E-Clipse HVAC
Default on page 53.
•Basic connections are described in the following paragraphs. Alternate
configurations using the E-Clipse Bypass macro are described in the ACH550 User’s Manual.
•On Terminal Block X1 inside the ACH550, analog inputs and outputs and
additional digital input and relay output connections (AI1, AI2, AO1, AO2,
DI1…DI6 and RO1…RO6) are available for use.
Note: The E-Clipse Bypass control circuitry uses serial communications connections
(X1:28…X1:32) inside the ACH550. These connections are not available for any
other purpose and must not be reconfigured.

Basic connections
The figure on page 53 shows the basic
control connections for use with the EClipse Bypass HVAC Default macro.
These connections are described in the
following paragraphs.
In typical installations, only analog input
wires connect to the ACH550 terminal
block, with other control connections
made on the E-Clipse Bypass control
board.
Use wire ties to permanently affix control/
communications wiring to the hooked wire
race tie points provided, maintaining a
minimum 6 mm (1/4") spacing from power
wiring.
Drive’s power connection terminals
The following tables list power and motor cable terminal sizes for connections to an
input circuit breaker or disconnect switch, a motor terminal block and ground lugs.
The tables also list torque that should be applied when tightening the terminals.
