(1) The ground fault sensing feature of the SMC-50 controller is intended for monitoring purposes only.

(2) External components may be needed. See the SMC-50 controller user manual, publication 150-UM011,

for additional information.

(3) See the SMC-50 Controller selection guide, publication 150-SG010

, or SMC-50 controller user manual, publication 150-UM011, for a list of compatible 20-COMM-X communication modules.

(4) When installed in an SMC-50 controller, 20-COMM-X modules physically reside in the space assigned to Port 9, but connect to DPI Port 4 with a ribbon cable that is supplied with the communications

module.

(5) For most systems, a single HIM device is used. You can use multiple HIMs by using DPI Port 2 and a DPI Port-Splitter See the SMC-50 controller user manual, publication 150-UM011,

for additional

information.

ATTENTION: The ground fault sensing feature of the SMC-50 controller is

intended for monitoring purposes only and not as a ground fault circuit

interrupter for personnel protection as defined in Article 100 of the NEC. The

ground fault sensing feature has not been evaluated for conformance to

UL 1053.
