R—RIM module is required to restrain any devices.

Numerical References—Maximum number of upstream circuit breakers which can be restrained without requiring a RIM Module.

ENGLISH

Circuit breaker terminals are shipped with terminals Z3, Z4 and Z5 jumpered to self- restrain the short-time and ground-fault functions. Remove the jumpers when activating zone-selective interlocking.
