3-2-3 Terminal Block Wiring
When wiring a Terminal Block, pay attention to wire sizes, grounding systems, and anti-
noise measures.

R88D-WN@H-ML2 (50 to 400 W)
Single-phase 200/230 V AC (170 to 253 V), 50/60 Hz (There is no L3
terminal.)
R88D-WN08H-ML2 (750 W)
Single-phase 200/230 V AC (170 to 253 V), 50/60 Hz (The L3 terminal is
not used; do not connect it.)
R88D-WN@H-ML2 (500 W to 3.0 kW)
Three-phase 200/230 V AC (170 to 253 V), 50/60 Hz
R88D-WN@L-ML2 (50 to 400 W)
Single-phase 100/115 V AC (85 to 127 V), 50/60 Hz (There is no L3 ter-
minal.)

These terminals normally do not need to be connected. If there is high
regenerative energy, connect an External Regeneration Resistor
between B1 and B2. (There is no B3 terminal.)
R88D-WN@H-ML2 (500 W to 3.0 kW)
Normally short between B2 and B3. If there is high regenerative energy,
remove the short bar between B2 and B3 and connect an External
Regeneration Resistor between B1 and B2.
Red These are the output terminals to the Servomotor. Be
careful to wire them correctly.
