3-2-3 Terminal Block Wiring

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

Do not connect anything to these terminals.
(Only the R88D-WT60H, R88D-WT75H, and R88D-WT150H have this termi-
nal.)
Normally short between 1 and 2.
When harmonic control measures are required, connect a DC Reactor be-
tween 1 and 2. tween 1 and 2
(The R88D-WT60H, R88D-WT75H, and R88D-WT150H do not have these
terminals.)
Do not connect anything to these terminals.

30 to 400 W: These terminals normally do not need to be connected. If there
is high regenerative energy, connect an External Regeneration Resistor be-
tween B1 and B2. tween B1 and B2.
500 W to 5 kW: Normally short between B2 and B3. If there is high regenera-
tive energy, remove the short bar between B2 and B3 and connect an Exter-
nal Regeneration Resistor between B1 and B2. nal Regeneration Resistor between B1 and B2
6 to 15 kW: Connect an External Regeneration Resistance Unit between B1
and B2.
