*1. A recommended product is listed in 4-3, Wiring Confirming
to EMC Directives.
*2. Do not use shielded cables for power cables.
*3. Recommended relay: MY relay by OMRON (24 VDC 2A)
Select one that matches the ratings of the brake etc. to be used.
*4. Models with a built-in Regeneration Resistor

XB
(KN04L-ECT-L, KN08H-ECT-L, KN10H-ECT-L, and
KN15H-ECT-L) have B2 and B3 shorted. When the
(*3)
amount of regeneration is large, remove the connection
between B2 and B3 and connect the Regeneration
Resistor between B1 and B2.
*5 There is no Internal Regeneration Resistor for KN01L-ECT-L,
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.
