９．Selection Of Peripheral Devices; Selection Of Wiring Equipment - Toshiba TOSVERT VF-P7 Instruction Manual

9. Selection of peripheral devices
・ When using the inverter without the front cover, be sure to place the inverter unit inside a
cabinet. If they are used outside the cabinet, it may cause electric shock.
Mandatory
・Be sure to ground every unit. If not, it may cause electric shock or fire on the occasion of
failure, short-circuit or electric leak.
Be grounded

(*1): Indicates wire sizes of input terminals R, S, T and output terminals U, V, W. Wiring distance is supposed to
be 30 m at maximum.
(*2): Cable sizes in this table is in case of 75 degree copper wire.
(*3): For the control circuit, use shielded wires whose size (cross-section) is 0.75 mm
(*4): For the earth cable, use wires larger than the specified ones in size (cross-section).
(*5): Do not connect more than two wires to a terminal block (except for terminal blocks of 2900, 2110K, 4160K
to 4315K and PA terminals of models that have only one PA terminal). If wiring with more than two wires is
needed, set a external relay terminal.
