Main breaker power “on” 
•
Power “on” to PH-X, Y and Z
OVERLOAD CIRCUIT PROTECTION
•
Electromagnetic breakers, with  
 
a long time delay curve, provide both  
 
manual on/off switching and trips  
 
automatically in an overload condition
LOCAL/OFF/REMOTE SWITCHING
•
Local: Power “on or off” to the switched  
 
outlets
•
Off: When breaker is “on” but this switch  
 
is in the “off” mode, you will have power  
 
to the unswitched outlets only
•
Remote: Power “on or off” to the  
 
switched outlets via a remote device
•
When using the Latching remote option,  
 
the selection switch is wired for  
 
Remote/Off/Remote - There is no local  
 
control
MULTIPLE TIME DELAY™ (MTD™)
•
Activated “Locally” or “Remotely”, PH-X  
 
powers up, followed 4-seconds later by  
 
PH-Y, which is followed 4-seconds later  
 
PH-Z, then 4-seconds later the  
 
sequenced remote activates the next 
system in line
(4 N/O) REMOTE I/O PORTS
•
Remote on/off and EPO control, EPO  
 
overrides remote and local control
•
Sequence Power Up additional
