8.3.3 Running the inverter by terminal commands
(Note 1) When connecting an optional DC reactor (DCR), remove the jumper bar from the terminals [P1] and [P (+)].
(Note 2) Install a recommended molded-case circuit breaker (MCCB) or an earth-leakage circuit-breaker (ELCB)
(with an overcurrent protection function) in the primary circuit of the inverter to protect wiring. At this time,
ensure that the circuit breaker capacity is equivalent to or lower than the recommended capacity.
(Note 3) Install a magnetic contactor (MC) for each inverter to separate the inverter from the power supply, apart
from the MCCB or ELCB, when necessary.
Connect a surge killer in parallel when installing a coil such as the MC or solenoid near the inverter.
(Note 4)
THR
function can be used by assigning code "9" (external alarm) to any of the terminals [X1] to [X5], [FWD]
and [REV] (function code: E01 to E05, E98, or E99).
(Note 5) Frequency can be set by connecting a frequency-setting device (external potentiometer) between the
terminals [11], [12] and [13] instead of inputting a voltage signal (0 to +10 VDC, 0 to +5 VDC or +1 to
+5 VDC) between the terminals [12] and [11].
(Note 6) For the control signal wires, use shielded or twisted pair wires. Ground the shielded wires. To prevent
malfunction due to noise, keep the control circuit wiring away from the main circuit wiring as far as possible
(recommended: 10 cm or more). Never install them in the same wire duct. When crossing the control circuit
wiring with the main circuit wiring, set them at right angles.
