*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 for a
rated inductive load of 2 A (24 VDC).
*3. Models with a built-in Regeneration
Resistor (KN20H-ECT-L) have B2 and
B3 shorted. When the amount of
regeneration is large, remove the
connection between B2 and B3 and
connect a Regeneration Resistor
between B1 and B2.
