General Information
Transfer Switch Data Decal
A data decal is permanently affixed to the transfer switch
enclosure. Use this transfer switch only with the specific
limits shown on the data decal and on other decals and
labels that may be affixed to the switch. This will prevent
damage to equipment and property.
When requesting information or ordering parts for this
equipment, make sure to include all information from the
data decal.
For future reference, record the Model and Serial
numbers in the space provided on the front cover of this
manual.
Transfer Switch Enclosure
The standard switch enclosure is a National Electrical
Manufacturer's Association (NEMA) and UL 3R type. UL
and NEMA 3R (indoor/outdoor rated) type enclosures
primarily provide a degree of protection against falling
rain and sleet; are undamaged by the formation of ice on
the enclosure.

Load Management Options
Load management systems are designed to work
together to prevent a generator from being overloaded by
large appliance loads. A Smart A/C Module (SACM) is
provided as standard equipment with this switch. An
optional Smart Management Module (SMM) is also
available.

Smart A/C Module (SACM)
Up to four air conditioner loads can be managed by the
SACM. The SACM manages the loads by "shedding" the
connected loads in the event of a drop in generator
frequency (overload). Loads to be "shed" are in 4 priority
levels on the module.
See
Figure
for an air conditioner. To control an air conditioner, no
additional equipment is required. Internal normally closed
relays interrupt the 24 VAC thermostat control signal to
disable the air conditioner load.
Four LEDs, located on the SACM (B), illuminate when a
load is connected and powered.

even when the transfer signal is inactive. The Generator
