Wiring To Comply with EMC To declare the conformity with the requirements for CE Mark,
8720MC-RPS Regenerative Power Supply must comply with both
EMC directive and low voltage directive. This section describes
notes on wiring to comply with EMC directive.
Important: 8720MC-RPS Regenerative Power Supply itself is not
subject to Machine directive. When 8720MC-RPS Regenerative
Power Supply is combined with other equipment, control cabinet
and machine, it is needed to declare the compliance with Machine
directive. Noise level will vary depending on the installation and
wiring of 8720MC-RPS Regenerative Power Supply, other
equipment and control cabinet. It has been already confirmed that
8720MC-RPS Regenerative Power Supply complies with EMC
standards only when 8720MC-RPS Regenerative Power Supply is
composed of the component parts designated by Reliance Electric.
In order for users to declare the conformity with the requirements
for CE Mark, do not fail to confirm that the unit complies with
EMC standards on the final conditions after completion of
installation and wiring.
The following show with which EMC standards each of the
8720MC-RPS Regenerative Power Supply complies.
8720MC-RPS027 EN61800-3:1996 including
Amendment A11:2000
8720MC-RPS065 EN55011:1991 Group 1, Class A, and
Amendment A1:1999
EN50082-2:1995
8720MC-RPS190 EN61800-3:1996 including
Amendment A11:2000
Wiring must be made taking into consideration of the following
countermeasures since there is the possibility that input and output
lines of the 8720MC-RPS Regenerative Power Supply may yield
strong noise.
1. Use a control cabinet made of metal for installing the 8720MC-
RPS Regenerative Power Supply (It has been confirmed that
this unit complies with EMC standards when installed inside the
control cabinet).
2. Install a line filter designated by Reliance Electric to the power
input line of the 8720MC-RPS units. Wiring to the line filter
must be as short as possible.
3. Because current will leak to the earth when a line filter is
installed, connection to the earth must be secured. Due to
leaked current, the earth leakage breaker may malfunction.
Select a proper breaker complying with leaked current (Rated
current 100 to 500mA and operating time within 0.1 to 2
seconds).
4. The control cabinet must be securely grounded. Wiring to be
taken into grounding terminal of the control cabinet must be as
thick and short as possible.
