Setting Priorities

High priority 240 VAC loads should be set to the highest
priorities so those loads recover first in the event of
generator/inverter overload.
NOTE: The highest priority, and first load to activate is
Priority 1. The last load to activate is Priority 8.
Setting priority determines timing for 3 scenarios:
•
Order in which loads recover
•
Delay time until power returns during an outage
•
Delay time for post load shed recovery

prioritization of loads.

Priority 1 - Baseboard heat
Priority 2 - Air conditioner
Priority 3 - Range
Priority 4 - Clothes Dryer
1. Set the priority of each SMM module as desired
(using the example configuration for reference).
2. Apply priority decal in a suitable location on
electrical panel
designations.
3. Record priorities on decal.

Setting Lockout

Early, Normally Open Contactor
Most installations will require the lockout switch to be
DISABLED. When performing a whole house backup
with a generator/PWRcell system not sized to manage all
household loads, SMM's can be used to disable
appliances or circuits during an outage. For non-essential
loads that will not be used on generator or inverter power,
set lockout switch to ENABLED.

Open Contactor)

NOTE: Early Version: When lockout switch is engaged
and running on generator, module will start in load shed
mode. After approximately 1 minute of run time the
module will enter lockout mode. When utility returns while
in lockout mode, the module will delay for 2 minutes
before returning to load shed mode. After a 4 minute
timer expires the load will be activated.

Function
If overloaded, module sheds
load until utility returns.
Contactor is OPEN.
NOTE: Early version goes into
lockout mode. Load is never
activated until Utility returns.
Power is available on module
output (contactor output).
Contactor is CLOSED.
Module operates with standard
load shed logic. Contactor is
OPEN or CLOSED per logic.
Power is available on module
output (contactor output).
Contactor is CLOSED.
