1 Caution: B e s u re t o re a d t he L 2 00 2 In verter Manual and follow its Cautions and W arnings for the initial pr oduct installation. This Quick Refer ence Guide is intended for refer enc e use by experienced users in servic ing existing installations.
2 T ermin al Tightening T orque and Wire Size The wire size range and tightening torq ue for field wiring terminals are presented i n the tables below . 200V Models Motor output In verter Model Wire S ize (A WG) T orque kW HP ft-lbs (N-m) 0.2 1/4 –002NFE(F)2/NFU2 16 0.
3 Wire Connec tors Wa r n i n g : Field wirin g connections must be made by a UL Listed and CSA Certified ring lug terminal connector sized for the wir e gauge being used. The connector must be fixed using the crimping tool specified by the con- nector manufactur er .
4 Motor Overload Protection Hitachi L200 2 in verters provide solid state motor ov erload protection, which depends on the proper sett ing of the following para meters: • B012 “electronic ov erloa.

8 Basic Wiring Dia gram The following wiring diag ram show s the power and motor connections for basic operation. The op tional signal input wiring supports e xternal Fwd and Rev Run command, an d a speed potentiome ter .
9 In ver ter Ke ypad Operation • Run/Stop LED – ON when the inv erter output is ON and the motor is de veloping torque , and OFF when the in verter ou tput is OFF (Stop Mode). • Program/Monitor LED – ON when the inv er ter is ready for parame- ter editing (Program Mode).
10 • Para meter Disp lay – A 4-digit, 7-segment display for parameter s and function codes. • Display Units: Hertz/Amperes – One of these LEDs will be O N to indicate the units associated with the parameter display . • Po wer LED – ON when the power input to the inv erter is ON.

12 P owerup T est The Powerup T est procedure uses minimal pa rameter settings to run the motor . The procedure describes two alternati ve methods for commanding the in verter: via the in verter keypad , or via the lo gic terminals . • Check power input and m otor output wiring (see page 8 diagram) .
13 Error Codes The L200 2 series inv erters will trip on over -current, over-v oltage, and under-v o ltage to protect the in verter . The motor output turns OFF , a llo w- ing the motor to free-run to a stop. Pr ess the Stop/Reset key to reset the in verter and clear the error .
14 Erro r T rip Conditions Use function code D081 to access the er ror trip conditions for the current error as shown in the table below . Use the Up and Down arro w keys to scroll through the trip c ondition parameters. E35 Thermistor • Thermistor input, [THM] and [L], is over the temp.
