APPENDIX
Wiring protection
For installation Class T, Class J, Class CC, or Class L fuse, or UL 489 Molded Case Circuit Breaker (MCCB) according to the local direc
-
tives must be provided.
For the FR-A820 series, Class T, Class J, or Class CC fuse, or UL 489 Molded Case Circuit Breaker (MCCB) must be provided.
*1
Maximum allowable rating by US National Electrical Code. Exact size must be chosen for each installation.
*2
Select an appropriate molded case circuit breaker with a rating that is suitable for the size of the cable.
For wiring protection of the converter unit (FR-CC2) refer to "FR-A802-R2R Instruction Manual (Hardware)".
A.1.3 Short circuit ratings
O
200 V class
Suitable for use in a circuit capable of delivering not more than 100 kA rms symmetrical amperes, 240 V maximum.
O
400 V class
Suitable for use in a circuit capable of delivering not more than 100 kA rms symmetrical amperes, 500 V 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).
