Conformance to UL and CE Markings
Information regarding conformance to UL and CE markings is provided in this section.
‹ CE Markings
CE markings indicate conformance to safety and environmental standards that apply to business transactions
(including production, imports, and sales) in Europe. There are unified European standards for mechanical
products (Machine Directive), electrical products (Low Voltage Directive), and electrical noise (EMC Direc-
tive). CE markings are required for business transactions in Europe (including production, imports, and sales).
The Varispeed G7-Series Drives bear CE markings indicating conformance to the Low Voltage Directive and
the EMC Directive.
• Low Voltage Directive: 73/23/EEC
93/68/EEC
• EMC Directive: 89/336/EEC
92/31/EEC
93/68/EEC
Machinery and installations that incorporate the Drive are also subject to CE markings. It is ultimately the
responsibility of customers making products incorporating the Drive to attach CE markings to the finished
products. The customer must confirm that the finished products (machines or installations) conform to the
European Standards.
‹ Requirements for Conformance to CE Markings
„ Low Voltage Directive
Varispeed G7-Series Drives satisfy testing for conformance to the Low Voltage Directive under the conditions
described in European Standard EN50178.
Requirements for Conformance to the Low Voltage Directive
Varispeed G7-Series Drives must satisfy the following conditions in order to conform to the Low Voltage
Directive.
• It must be used under conditions corresponding to overvoltage category 3 or less and pollution degree 2 or
less as specified in IEC664.
• Input fuses:
For details on selecting fuses, refer to Table 10.2 Selection Requirements for Input Fuses with Examples.
• With Drives CIMR-G7U2018 to 2110 and CIMR-G7U4018 to 4300, an enclosure preventing foreign mat-
ter from entering from the top or front sides is required (IP4X or higher: panel installation).
