9. Taking measures to satisfy the CE/UL/CSA standards

9.1 How to cope with the CE standard

In Europe, the EMC directive and the low-voltage directive, which took effect i n 1996 and 1997, respectively, make it
obligatory to put the CE mark on every applicable product to prove that i t complies with the directives. Inverters do
not work alone but are designed to be installed in a control panel and always u sed in combination with other
machines or systems which control them, so they themselves are not consi dered to be subject to the EMC directive.
However, the CE mark must be put on all inverters because they are subject to the l ow-voltage directive.
The CE mark must be put on all machines and systems with built-in inve rters because such machines and systems
are subject to the above directives. It is the responsibility of the manufa cturers of such final products to put the CE
mark on each one. If they are “final” products, they might also be subject to machine-related directives. It is the
responsibility of the manufacturers of such final products to put the CE mark o n each one. In order to make machines
and systems with built-in inverters compliant with the EMC directive and th e low-voltage directive, this section
explains how to install inverters and what measures should be taken to satisf y the EMC directive.
We have tested representative models with them installed as described later in th is manual to check for conformity
with the EMC directive. However, we cannot check all inverters for conformity becau se whether or not they conform
to the EMC direction depends on how they are installed and connected. Applicabl e EMC standards vary depending
on the composition of the control panel in which the inverter is installed, th e relationship with other electrical devices
installed in the control panel, wiring conditions, equipment layout, and so on , so you should check whether your
machine or system complies with EMC standards as a whole. Therefore, please ve rify for yourself whether your
machine or system conforms to the EMC directive.

9.1.1 EMC directive!

The CE mark must be put on every final product that includes an inverter( s) and a motor(s). The VF-AS1 series of
inverters complies with the EMC directive if an EMC filter recommended b y Toshiba is connected to it and wiring is
carried out correctly.
The EMC standards are broadly divided into two categories; immunity- and e mission-related standards, each of
which is further categorized according to the operating environment of eac h individual machine. Since inverters are
intended for use with industrial systems under industrial environments, they fa ll within the EMC categories listed in
Table 1 below. The tests required for machines and systems as final products are almost the same as those requi red
for inverters.
