16 ACH580 Installation, Operation and Maintenance Manual
ACH580-01 Installation
4. Install wiring
WARNING! Ensure the motor is compatible for use with the ACH580. The ACH580
must be installed by a competent person. If in doubt, contact your local ABB sales or
service office.
WARNING! If the drive will be connected on an IT (ungrounded) system, make sure
neither the EMC filter nor the ground-to-phase varistor are connected. If the drive will
be connected on a corner-grounded TN system, make sure you have not connected
the EMC filter. See Checking the compatibility with IT (ungrounded) and corner-
grounded TN systems (North America) on page 17.
Checking the insulation of the assembly
WARNING! Do not make any voltage tolerance or insulation resistance tests on any
part of the drive as testing can damage the drive. The drive has been tested at the
factory.
1. Check the insulation of the input cable according to local regulations be
fore
con
nection to the drive. Minimum cable temperature rating of 167 Β°F (75
Β°C) must be
use
d.
2. With the motor cable connected to the motor, but NOT to the drive outpu
t terminals
T1/U,
T2/V and T3/W, measure the insulation resistance between the
phase
con
ductors and between each phase conductor and the Protective Ea
rth (PE)
con
ductor, using a measuring voltage of 1000 V DC. The insulation resistan
ce must
exceed 1
00 Mohm at 25 Β°C.
Ground connections
For personnel safety, proper operation and to reduce electromagnetic emission/pick-
up, the drive and the motor must be grounded at the installation site.
β’ Conductors must be adequately sized as required by safety regulations.
β’ Power cable shields must be connected to the drive PE terminal in order to meet
safety regulations.
β’ Power cable shields are suitable for use as equipment grounding conducto
rs only
when
the shield conductors are adequately sized as required by safe
ty
regu
lations.
β’ In multiple drive installations, do not connect drive terminals in series.
