*1. A recommended product is listed in 4-3, Wiring
Confirming to EMC Directives.
*2. Recommended relay: MY relay by OMRON (24-V)
MY2 relay by OMRON can be used because its
CN1
rated inductive load is 2 A (24 VDC).

*3. Models with a built-in Regeneration Resistor
1 XB
(KN04L-ECT-L, KN08H-ECT-L, KN10H-ECT-L and
(*2)
KN15H-ECT-L) have B2 and B3 shorted. When the
2
amount of regeneration is large, remove the
connection between B2 and B3 and connect a
Regeneration Resistor between B1 and B2.
*4. There is no Internal Regeneration Resistor for
KNA5L-ECT-L to KN02L-ECT-L, and KN01H-ECT-L
to KN04H-ECT-L. When the amount of regeneration
is large, connect the necessary Regeneration
Resistor between B1 and B2.
