CE Compliance Requirements
In addition to the local and regional safety requirements, this section describes additional criteria that must be met to qualify for Eur opean 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 instructi ons provide a means of compliance for the Q7 Flow. A Technical Construct ion F ile (TFC) indicates the rationale used to declare compliance and is on file at Toshiba International Corporation, Houston, Texas, U.S.A.
Using RCD Protection
Where a residual-current-operated protective dev ice (RCD) is used to guard against direct or indirect contact, only an RCD of Type B is allowed on the s upply side of this Electronic Equi pment.
Otherwise, anot her protective measure shall be applied, such as sep aration of the Electronic E quipm ent fro supply side by a transformer.
EMC Installation Guidelines
All systems placed on th e 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 ha ve be en s cre ened and are in 100% compliance with the foll owing s tandards:
