When using an optional internal braking resistor
An optional internal braking resistor should be con-
nected to terminals P(+) and DB. Connect the wires from
the braking resistor, following the procedure described
in “When a dc reactor is not to be connected together
with the braking resistor” or “When using a dc reactor
together” on the previous page, as applicable.
Figure 2.9 Braking Resistor Connection
TIP: The option internal braking resistor type is available
only in 3-phase 230V and 460V models of 2 hp and
above.
(5) DC link circuit terminals, P (+) and N (-)
These are provided for the dc bus link circuit system.
Connect these terminals with terminals P(+) and N (-) of
other drives.
NOTE: Consult GE Fuji if these terminals are to be used.
(6) Main circuit power input terminals, L1/R, L2/S,
and L3/T (for 3-phase voltage input) or L1/L and L2/N
(for 1-phase voltage input)
1) For safety, make sure that the Molded Case Circuit
Breaker (MCCB) or Magnetic Contactor (MC) is
disconnected before wiring the main circuit power
input terminals.
2) Connect the ground wire of the main circuit power
input terminals (L1/R, L2/S and L3/T or L1/L and
L2/N) to the ground terminal (G).
3) Connect the main circuit power supply wires (L1/R,
L2/S and L3/T or L1/L and L2/N) to the input
terminals of the drive via an MCCB or Ground Fault
Circuit Interrupter (GFCI), and MC if necessary.
It is not necessary to align phases of the power
supply wires and the input terminals of the drive
with each other.
TIP: It is recommended that a manual on/off magnetic
contactor be connected. This is to enable you to discon-
nect the drive from the power supply in an emergency
(e.g. when the protective function is activated) so as to
prevent accidents or damage.

2.3.5 Replacing the Main Circuit Terminal Block (TB)
Cover
1) As shown in Figure 2.11, pull out the wires from the
main circuit terminals in parallel.
2) Hold both sides of the main circuit TB cover
between thumb and forefinger and slide it back into
place. Pull the wires out through the grooves of the
main circuit TB cover.
NOTE: When replacin the main circuit TB cover, take
care not to apply any stress to the wires. Stress on the
wires imposes a mechanical force on the main circuit
terminal screws, loosening them.
