2-5 Installation and Connection
2
(3) DC reactor connecting terminals (P1, P (+))
a. Use this terminal to connect a DC
reactor (option). Remove the jumper
connected in the factory before
connecting the DC reactor.
b. Do not remove the jumper if no DC
reactor is used.
Cut the barrier in the main circuit
terminal block cover for the P1, P (+),
DB and N (-) cable port when connecting
wiring.
(4) External braking resistor connecting
terminals (P (+), DB)
VXSM is not equipped with a braking
resistor. An external braking resistor
(option) is necessary for frequent operation
or heavy duty inertia load operation to
enhance the braking performance.
a. Connect the P (+) and DB terminals of
the external braking resistor to the P (+)
and DB terminals of the inverter.
b. Arrange devices so that the wiring
length is within 5 m and twist or closely
(in parallel) place the two cables.
(5) Inverter grounding terminal ( G )
Ground the grounding terminal G for
safety and noise reduction without fail. The
metallic frame of electrical equipment must
be grounded in accordance with national
regulations to avoid electric shock, fire and
other disasters

CAUTION
• Check that the number of phases
and the rated voltage of the product
agrees with the number of phases and the
voltage of the AC power supply.
• Do not connect the AC power cables to the
output terminals (U, V, W).
Otherwise injuries could occur.
• Do not connect a braking resistor directly
to the DC terminals (P (+), N (-)).
Otherwise fire could occur.
