directives must be provided.
*1
Maximum allowable rating by US National Electrical Code. Exact size must be chosen for each installation.
For wiring protection of the converter unit (FR-CC2) refer to the FR-CC2 Instruction Manual-
A.1.3 Short circuit ratings
200V class
Suitable for use in a circuit capable of delivering not more than 100kA rms symmetrical amperes, 264V maximum.
400V class
Suitable for use in a circuit capable of delivering not more than 100kA rms symmetrical amperes, 550V or 600V
maximum.
A.1.4 Machinery directive
The frequency inverter itself is not a machine in the spirit of the EU machinery directive. The start up of the frequency
inverter in a machine is prohibited so long until it has been confirmed that the entire machine complies with the provisions
of Directive 98/37/EC (from 29.12.2009 Machinery Directive 2006/42/EC).
