Rockwell Automation 161 SERIES A - Manual (Page 36)

Bulletin 161
30
Appendix A: CE Conformity
The Bulletin 161 is CE marked for conformity to the Low Voltage (LV) Directive 73/23/EEC when installed as
described. It also has been tested to meet the Council Directive 89/336/EEC Electromagnetic Compatibility
(EMC).
The standards used are:
LV EN50178, EN60204-1, EN60950
EMC Emissions: EN61800-3 (EN55011, Group 1, Class B)
Immunity: EN61800-3 (Industrial Environment).
Important : The conformity of the drive and filter to any standard does not guarantee that the entire
installation or machine will conform. Many other factors can influence the total installation and
only direct measurements can verify total conformity. It is therefore the responsibility of the
machine manufacturer or end user to ensure that conformity is met.
General Notes and Instructions:
)
The motor cable should be kept as short as possible in order to avoid electromagnetic
emission as well as capacitive currents. The cable length increases the capacitive current
and electromagnetic emission.
It is recommended that the motor cable length does not exceed 50 m.
It is always recommended to install output reactors if the cable length exceeds 50 m.
)
The filters contain capacitors between the phases and the phases to ground as well as
suitable discharging resistors. But after switching off the line voltage wait a minimum of
60 seconds before removing protective covers or touching terminals to avoid an electric
shock.
)
The use of ground fault monitoring devices (RCD’s) is not recommended. If unavoidable
only monitoring devices which are suited for DC-, AC- and HF-ground currents (type B
RCD’s) should be used. It is recommended to use devices which responsiveness and time
characteristics are adjustable, to avoid nuisance tripping during power up the drive.
)
The thermal capacity of the line filter is guaranteed up to a maximum motor cable length of
50 m.
)
The line filters have been developed for use in grounded systems. Use in ungrounded
systems is not recommended.
Essential requirements for a conforming EMC installation
1. An input line filter module (see table below) must be installed to reduce conducted emissions.
