The FlexSeT ERMS feature for the main breaker in the FlexSeT switchboard is powered by the ERMS/ERM2 I-Line Enable Module (I-LEM) mounted in the I-Line section that is downstream of the main breaker. The main breaker must be in the ON position, and line side power must be present, to energize the switchboard bus and I-Line section before the ERMS function can be enabled. The ERMS function for the main breaker cannot be enabled or disabled if the main breaker is switched OFF or has TRIPPED. The ERMS/ERM2 I-LEM mounted in the I-Line section takes a few seconds after energization before it is available for use. Once the ERMS is enabled, the main breaker will retain the ERMS enabled state if the main breaker is switched OFF, has TRIPPED, or power is lost before disabling the ERMS.

Schneider Electric™ recommends that all feeder (downstream) breakers in the switchboard be switched OFF before switching ON the main breaker for any use cases where ERMS functionality is desired, including the startup of the FlexSeT switchboard.

Schneider Electric recommends that ERMS be enabled before switching OFF the main breaker when any maintenance or service is performed on the switchboard or downstream equipment. After turning the ERMS switch to ON and waiting a few seconds, confirm that the ERMS/ERM2 I-LEM switch’s internal light is illuminated blue and the main breaker's display flashes the ERMS legend before switching OFF the main breaker. The main breaker will retain the ERMS enabled state if the main breaker is switched OFF, has TRIPPED, or power is lost. The ERMS feature can be disabled once the main breaker is switched ON and the ERMS/ERM2 I-LEM has completed its startup sequence.
