*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
(KN08H-ECT-L to KN15H-ECT-L) have B2
and B3 shorted. When the amount of
regeneration is large, remove the connection
between B2 and B3 and connect the
Regeneration Resistor between B1 and B2.
