“C-tick” marking
“C-tick” marking is pending as follows.
“C-tick” marking is required in Australia and New Zealand. A “C-tick” mark is attached to each drive in
order to verify 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.
Definitions
EMC stands for Electromagnetic Compatibility. It is the ability of electrical/electronic equipment to
operate without problems within an electromagnetic environment. Likewise, the equipment must not
disturb or interfere with any other product or system within its locality.
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 radiofrequency spectrum by introducing technical limits for emission from electrical/
electronic products.
First environment includes establishments connected to a low-voltage network which supplies buildings
used for domestic purposes.
Second environment includes establishments connected to a network not supplying domestic premises.
Restricted distribution: mode of sales distribution in which the manufacturer restricts the supply of
equipment to suppliers, customers or users who separately or jointly have technical competence in the
EMC requirements of the application of drives.
Unrestricted distribution: mode of sales distribution in which the supply of equipment is not dependent
on the EMC competence of the customer or user for the application of drives.
Compliance with IEC 61800-3
First environment (restricted distribution)
The drive complies with the limits of IEC 61800-3 with the following provisions:
1. The drive is equipped with EMC filter E202.
2. The drive is installed according to the instructions given in the Hardware Manual.
3. The motor and control cables used are selected as specified in the Hardware Manual.
4. Maximum cable length is 100 metres.
Note: The drive must not be equipped with the EMC filter E202 when installed to IT (unearthed)
systems. The mains becomes connected to earth potential through the EMC filter capacitors. In IT
systems this may cause danger or damage the unit.
