➀
Do not connect any additional loads to these
terminals. These “parasitic” loads may cause
incorrect operation.
➁
When set for External Bypass mode, the SMC
Flex can be used to control a properly sized
external contactor and overload once the motor
reaches full speed. The SMC-Flex overload
functionality is disabled in this mode.
➂
RC Snubbers are required on inductive type
loads connected to auxiliary contacts.
➃
Control power on units rated 625…1250 A is
pre-wired internally, from terminal block CP1.
