Technical data
The drives are to be used in a controlled environment. See section Ambient
conditions on page 1-328 for specific limits.
For open type enclosures, units must be mounted inside an enclosure per National
Electrical Code and local electrical codes. Open type enclosures are IP21 / UL type
1 units without the conduit box and/or cover, or IP54 / UL type 12 units without the
conduit plate and/or top cover.
EMC (Europe, Australia, and New Zealand)
This section describes conformance with EMC requirements (in Europe, Australia,
and New Zealand).
CE Marking
When a CE mark is attached to the ACH550 AC drive, it verifies that the drive follows
the provisions of the European Low Voltage and EMC Directives (Directive
73/23/EEC, as amended by 93/68/EEC and Directive 89/336/EEC, as amended by
93/68/EEC). The corresponding declarations are available on request and can be
found using the internet at: http://www.abb.com.
The EMC Directive defines the requirements for immunity and emissions of electrical
equipment used in European Economic Area. The EMC product standard
EN 61800-3 covers the requirements stated for drives, such as the ACH550. The
drive complies with the First environment (restricted distribution) and Second
Environment limits of EN/IEC 61800-3.
C-Tick Marking
When a C-Tick mark is attached to the ACH550 drive, it verifies compliance with the
relevant standard, IEC 61800-3 (1996) – Adjustable speed electrical power drive
systems – Part 3: EMC product standard including specific test methods, mandated
by the Trans-Tasman Electromagnetic Compatibility Scheme. The drive complies
with the First environment (restricted distribution) and Second Environment limits of
EN/IEC 61800-3.
Electromagnetic Environments
Product standard EN 61800-3 (Adjustable speed electrical power drive systems -
Part 3: EMC product standard including specific test methods) defines
First
Environment as environment that includes domestic premises. It also includes
establishments directly connected without intermediate transformers to a low voltage
power supply network which supplies buildings used for domestic purposes.
Second Environment includes establishments other than those directly connected
to a low voltage power supply network which supplies buildings used for domestic
purposes.
