Step 5:  The wiring enters the inverter through an entr y/exit plate. For plastic plates, remove the 
knockout portions of the plate. For metal plates  with rubber grommets, cut an “X” in the center 
of the grommet as shown. Be especially careful to  avoid cutting into the thick outer ring, so that 
the wiring will have a cushion from contacting the metal plate.
NOTE:  Some inverter models will have a wiring box for NEMA rating compliance. Make sure...

Determining Wire 
and Fuse SizesThis section includes tables for 200V class a nd 400V class inverters (on the next page). The 
following notes will help you read the tables in this section:
 Locate the row corresponding to the motor size and particular inverter in your application.  The maximum motor current determin es the recommended wire sizes.
 The length column specifies that some inverters can optionally use a smaller wire gauge...

Determining wire and fuse sizes, continued...
Note 1: Field wiring must be made by a UL-liste d and CSA certified ring lug terminal 
connector sized for the wire gauge involve d. The connector must be fixed by using 
the crimping tool specified by  the connector manufacturer.
Note 2: Be sure to consider the capacity of the circuit breaker to be used.
Note 3: Be sure to use a larger wire gauge if power line length exceeds 66 ft (20m).
Note 4:...
