Warning

1, 2, 3...

1. After turning off the main circuit powersupply, do not touch cir-

cuitcomponentsuntilthe“CHARGE”lampisextinguished.The

capacitors are still charged and can be quite dangerous.

2. Do not change the wiring while power is applied to the circuit.

3. Do not check signals during operation.

4. Be sure to ground 3G3SV using the ground terminal G (E).

5. Never connect main circuit output terminals, T1 (U), T2 (V), T3

(W), to AC main circuit supply.

Caution

1. Allthepotentiometersof3G3SVhavebeenadjustedatthefac-

tory. Do not change their settings unnecessarily.

2. Donotperformwithstandvoltagetestonanypartofthe3G3SV

Main Circuit Input/Output

1, 2, 3...

1. Phase rotation of input terminals L1 (R), L2 (S), L3 (T) isavail-

able in either direction, clockwise and counterclockwise.

2. When inverter output terminals T1 (U), T2 (V), and T3 (W) are

connected to motor terminals T1 (U), T2 (V), and T3 (W), re-

spectively,motorrotatescounterclockwise, viewed from oppo-

site drive end, upon forward operation command. To reverse

the rotation interchange any two of motor leads.

3. Never connect AC main circuit power supply to output termi-

nals T1 (U), T2 (V), and T3 (W).

4. Careshouldbetakentopreventcontactofwiringleadswiththe

3G3SV cabinet, or a short-circuit may result.

5. Never connect power factor correction capacitor or noise filter

to 3G3SV output.

6. Never open or close contactors in the output circuit unless in-

verter is properly sized.

Grounding Ground the casing of the 3G3SV using ground terminal G (E).

1, 2, 3...

1. Ground resistance should be 100 or less.

2. Never ground the 3G3SV in common with welding machines,

motors, and other large-current electrical equipment, or

ground pole. Run the ground lead in a separate conduit from

leads for large-current electrical equipment.

3. Use the ground leads which comply with AWG standards and

make the length as short as possible.

4. Where several 3G3SV units are used side by side, all the units

should preferably be grounded directly to the ground poles.

However,connecting all the ground terminalsof3G3SV inpar-

allel, and grounding only one of 3G3SV to the ground pole is

also permissible (Fig. 4). However, do not form a loop with the

ground leads.
