SlowSwitchingregulationlimitstheswitching
frequencyto10hz.(maximum),whichcan
eliminatenoiseissuesinsomesystems.
PWMchargingisselectedbydefault.
To Install the Terminal Cover (requiredbyUL/ETLlistedsystems):
1. Removethetwolowerscrewsfrom
thefaceplate.
2. AligntheTerminalCoverover
theholes.
3. InsertthescrewsremovedinStep1and

withlead‐acidorNiCdbatteries.NiMH,Li‐ion,
andotherbatterychemistriesarenotcompatible
withtheSunSaverchargingalgorithm.

WARNING: Explosion Hazard
NeverinstalltheSunSaverinanenclosurewithvented/
floodedbatteries.Batteryfumesareflammableand
willcorrodeanddestroytheSunSavercircuits.Ensure
sufficientventilation.
Step 1: Choose Mounting Location
LocatetheSunSaveronaverticalsurfacewithin10feet(3m)ofthebattery
bankthatisprotectedfromdirectsun,hightemperatures,andwater.
Step 2: Check for Clearance and Ventilation
PlacetheSunSaverinthelocationwhereitwillbemounted.
Verifythatthereissufficientroomtorunwiresandthat
thereisampleroomaboveandbelowthecontrollerforairflow.
Step 3: Mark Holes
Useapencilorpentomarkthefour(4)mounting
holelocationsonthemountingsurface.
Step 4: Drill Holes
Removethecontrolleranddrill3/32”(2.5mm)
holesinthemarkedlocations.
Step 5: Secure Controller
Placethecontrolleronthesurfaceandalignthemountingholes
withthedrilledholesinstep4.Securethecontrollerinplace
usingtheMountingscrews(included).
