(3) DC reactor connecting terminal [P1, P(+)]
Use this terminal to connect a input power-factor correcting
DC reactor (optional). Remove the jumper connected in
the factory before connecting the DC reactor (see Figure
2-3-2. Use diagonal cutting pliers to cut the surface cover
barriers from P1, P(+) terminals before connection.
If no DC reactor is used, do not remove the jumper
(4) Drive grounding terminal [
G]
For safety and noise reduction, always ground the
drive grounding terminal [
G]. Grounding of the
metal frames of electric equipment must be done
in accordance with the applicable national and lo-
cal safety codes.
¬
Connect a short, heavy gauge wire to the
grounding terminal of the drive for connection
with a ground electrode installed exclusively
for the drive system.
!
CAUTION
1. Check that the number of phases and the rated voltage of this product
match the number of phases and voltage of the AC power supply
Risk of fire!
2. Never connect the AC power supply to the output terminals [U, V, W]
Risk of injury!
3.
Do not connect a braking resistor directly to the DC terminals [P(+), N(-)]
Risk of fire!

Connecting the control terminals
Table 2-3-2 lists the functions of the control circuit
terminals. The method of connecting a control circuit
terminal depends on how its function is set. Connect
the control circuit terminals according to the set func-
tions.

Figure 2-3-3 shows the circuit configuration.
Use a reliable contact.
