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 
the wire entry to the NEMA box also has pr otective cushion from chaffing of insulation.
 Before proceeding, plea se study the caution and  warning messages below.
WARNING:  Use 75°C Cu wire  only or equivalent.
WARNING: Open Type Equipment. For models SJ700–750H to SJ700–4000H.
WARNING: A Class 2 circuit wired with Class 1 wire or equivalent.
WARNING: Suitable for use on a circuit capable of delivering not more than 100,000 rms 
symmetrical amperes, 240 V maximum. For models with suffix L.
WARNING: Suitable for use on a circuit capable of delivering not more than 100,000 rms 
symmetrical amperes, 480 V maximum. For models with suffix H.
HIGH VOLTAGE:  Be sure to ground the unit. Otherwise,  there is a danger of electric shock 
and/or fire.
HIGH VOLTAGE:  Wiring work shall be carried out only by qualified personnel. Otherwise, 
there is a danger of electric shock and/or fire.
HIGH VOLTAGE: Implement wiring after chec king that the power supply is OFF. Otherwise, 
you may incur electric shock and/or fire.
HIGH VOLTAGE: Do not connect wiring to an inverter  or operate an inverter that is not 
mounted according the instructions given in this  manual. Otherwise, there is a danger of elec-
tric shock and/or injury to personnel.

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 if  the wires are shorter than 10m and the  inverter is located in an enclosure.
 Power Lines columns include wire s connecting to terminals [R, S, T, U, V, W, P, PD, and N]. 
Only power input and motor leads  will be fused: [R, S, T, U, V, and W]. The breaker ratings 
(GFI—ground fault interrupter) are slightly high er than fuse ratings to allow for nominal 
surges without tripping.
 The chassis ground columns li st the Hitachi-recommended AWG and the minimal AWG for 
UL conformity.
 The optional external braking re sistor wiring only applies to a few models that have a built-
in braking unit. The other models us e an optional external braking unit.
 Parallel wires increase effective wire gauge, and are denoted by “||” in the tables.
 Signal Lines, not listed in these tables, conn ect to the removable logic connector. The recom-
mended wire gauge for all wiring to  the logic connector is 28 AWG (0.75 mm
2). Be sure to 
use shielded wire fo r any analog signals.

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: Prepackaged (included) square washer is to  be used when the bare wire is directly 
connected to terminal with out using crimp contact (such as ring lug connector).
Note 5: When replacing J300-055HF or SJ300-055HFF2 inverter with SJ700-055HFF2, 
you may use power wiring size 2mm
2.
Note 6: Wire must be rated for operation up to 75°C.
