G7 ASD Operation Manual
CE Compliance Requirements
In addition to the local and regional safety requirements, this section describes additional criteria that
must be met to qualify for European Conformity (CE) certification. All relevant apparatus placed on
the European market is required to comply to the European Community directive on electromagnetic
compatibility (EMC). The following instructions provide a means of compliance for the 7-series of
ASDs. A Technical Construction File (TFC) indicates the rationale used to declare compliance and is on
file at Toshiba International Corporation, Houston, Texas U.S.A.
EMC Installation Guidelines
All systems placed on the European market are required to comply with the European Community
directive regarding electromagnet compatibility (EMC). Toshiba ensures that all systems deployed in
the European market have been screened and are in 100% compliance with the following standards:
•
Radiated Interference: EN 55011 Group 1 Class A
•
Mains Interference: EN 55011 Group 1 Class A
•
Radiated Susceptibility: IEC 801-3 1984
•
Conducted RFI Susceptibility:
pr
EN55101-4 (prIEC801-6) Doc 90/30270
•
Electrostatic Discharge: IEC801-2 1991
•
Electrical Fast Transient: IEC 801-4 1988
•
Surge: IEC1000-4-5 1995 2 KV line-to-line, 4 KV line-to-earth
•
Voltage Interruption: IEC 1000-4-11
General EMC Guidelines for Consideration
•
Input filters of the appropriate rating shall be used.
•
Proper grounding is a requirement.
•
Grounds shall be kept to the minimum length to accomplish the connection.
•
Grounds shall have low RF impedance.
•
A central ground shall employed in a complex system.
•
Paint or corrosion can hamper good grounding; remove as required.
•
Keep control and power cabling separated. Minimize exposed (unscreened) cable.
•
Use 3600 screened connections where possible.
CE Compliant Installation Guidelines
ASDs should be installed in accordance with the following guidelines.
1.
Filtering — An input filter shall be used with the ASD. A Schaffner FN258 series input filter of the
appropriate rating shall be mounted next to the ASD.
2.
Mechanical — The ASD and the associated equipment shall be mounted on a flat metallic
backplane. A minimum space of 5 cm (2 inches) shall be between the ASD and the filter to allow
for ventilation. The filter output cable is to be connected from the bottom of the filter to the ASD
power input and is to be the minimum length required for a connection. See
Table 1 on page 11
for
filter selection assistance.
