Technical data
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 293 .
UL/CSA markings
An UL mark is attached to ACS550 drives to verify that the drive follows the
provisions of UL 508C.
A CSA mark is attached to ACS550- U1 type drives to verify that the drive follows the
provisions of C22.2 NO. 14.
The ACS550 is suitable for use on a circuit capable of delivering not more than
100,000 RMS symmetrical amperes, 480 V maximum.
Branch circuit protection must be provided in accordance with local codes.
The ACS550 has an electronic motor protection feature that complies with the
requirements of UL 508C and, for ACS550-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 289 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 277 .
IEC/EN 61800-3 (2004) Definitions
EMC stands for E lectro m agnetic C ompatibility. It is the ability of electrical/electronic
equipment to operate without problems within an electromagnetic environment.
