Typically, when a system is in sleep mode, you cannot
communicate with the modules. In sleep mode, the SSRs open to
prevent current from flowing through the load. Consequently, the
system consumes minimal power and may dissipate less heat than
it does in normal mode. Refer to the Specifications section for more
information about power consumption and thermal dissipation.
