300 ACQ550-U1 User’s Manual
Technical data
C-Tick marking is required in Australia and New Zealand. A C-Tick mark is attached
to the drive to verify compliance with the relevant standard (IEC 61800-3 (2004) –
Adjustable speed electrical power drive systems – Part 3: EMC product standard
including specific test methods), mandated by the Trans-Tasman Electromagnetic
Compatibility Scheme.
The Trans-Tasman Electromagnetic Compatibility Scheme (EMCS) was introduced
by the Australian Communication Authority (ACA) and the Radio Spectrum
Management Group (RSM) of the New Zealand Ministry of Economic Development
(NZMED) in November 2001. The aim of the scheme is to protect the radio
frequency spectrum by introducing technical limits for emission from electrical/
electronic products.
Compliance with IEC/EN 61800-3 (2004)
See page 301 .
UL/CSA markings
An UL mark is attached to ACQ550 drives to verify that the drive follows the
provisions of UL 508C.
A CSA mark is attached to ACQ550- U1 type drives to verify that the drive follows the
provisions of C22.2 NO. 14.
The ACQ550 is suitable for use in a circuit capable of delivering not more than
100 kA RMS symmetrical amperes, 600 V maximum. The ampere rating is based on
tests done according to UL 508.
Branch circuit protection must be provided in accordance with local codes.
The ACQ550 has an electronic motor protection feature that complies with the
requirements of UL 508C and, for ACQ550-U1, C22.2 No. 14. When this feature is
selected and properly adjusted, additional overload protection is not required unless
more than one motor is connected to the drive or unless additional protection is
required by applicable safety regulations. See parameters 3005 (
MOT THERM PROT
)
and 3006 (
MOT THERM RATE
).
The drives are to be used in a controlled environment. See section Ambient
conditions on page 296 for specific limits.
Note: For open type enclosures, i.e. drives without the conduit box and/or cover for
IP21 / UL type 1 drives, or without the conduit plate and/or hood for IP54 /
UL type 12 drives, the drive must be mounted inside an enclosure in accordance
with National Electric Code and local electrical codes.
Brake choppers, when applied with appropriately sized brake resistors, will allow the
drive to dissipate regenerative energy (normally associated with quickly decelerating
a motor). Frame sizes R1 and R2 have a built-in brake chopper as standard
equipment. For frame sizes R3…R6, contact your ABB representative for
appropriate parts. See section
Brake components on page 285 .
