OL - Overload relay (electronic).
PC1,2,3 - SCR power cells.
R1 - Run relay, DPDT.
RS - Snubber resistor.
S - SCR overtemperature switch.
SCR - Silicon controlled rectifier.
TB1 - Terminal block.
X - Control transformer (control voltage).
MOV
Caution: Read Note
4 Turns (3 Loops)
Notes:
Control transformer must be properly connected for line voltage (see transformer nameplate).
Do not apply voltage to LCM terminals 12 and 13. Dry contact type only.
Number of cooling fans depends on the FLA rating.
Tachometer is only required when LCM is used in Tach Feedback mode.
MOVs are connected in parallel for greater energy absorption for control sizes above 420Amp FLA.
For factory supplied enclosure fans only.
