2.4.3 Terminal arrangement and screw specifications

2.4.3.1

Main circuit terminals

The tables and figures given below show the screw specifications and wire sizes. Note that the terminal
arrangements differ depending on the inverter types. In each of the figures, two grounding terminals ( G)
are not exclusive to the power supply wiring (primary circuit) or motor wiring (secondary circuit).
Use crimp terminals covered with an insulation sheath or with an insulation tube.
The recommended wires for main circuit terminals are selected according to the sizes conforming to
UL508C.

Note: A box ( ) in the above table replaces S or H depending on the enclosure.
When the inverter power is ON, a high voltage is applied to the following terminals.
Main circuit terminals: L1/R, L2/S, L3/T, P1, P(+), N(-), DB, U, V, W, R0, T0, R1, T1, AUX-contact (30A, 30B,
30C, Y5A, Y5C)
Insulation level
Main circuit ― Enclosure : Basic insulation (Overvoltage category III, Pollution degree 2)
Main circuit ― Control circuit : Reinforced insulation (Overvoltage category III, Pollution degree 2)
Relay output ― Control circuit : Reinforced insulation (Overvoltage category II, Pollution degree 2)
An electric shock may occur.
