4.6 Inspection and Maintenance
WARNING: RISK OF ELECTRICAL SHOCK.
NO POWER OR ACCESSORY TERMINALS ARE
ELECTRICALLY ISOLATED FROM DC INPUT, AND MAY
BE ENERGIZED WITH HAZARDOUS SOLAR VOLTAGE.
UNDER CERTAIN FAULT CONDITIONS, BATTERY COULD
BECOME OVER-CHARGED. TEST BETWEEN ALL
TERMINALS AND GROUND BEFORE TOUCHING.
AVERTISSEMENT: RISQUE DE CHOC
ÉLECTRIQUE.
NON ALIMENTATION OU AUX BORNES
D’ACCESSOIRES SONT ISOLÉS ÉLECTRIQUEMENT
DE L’ENTRÉE DE C.C ET DOIT ÊTRE ALIMENTÉS
À UNE TENSION DANGEREUSE SOLAIRE. SOUS
CERTAINES CONDITIONS DE DÉFAILLANCE, LA
BATTERIE POURRAIT DEVENIR TROP CHARGÉE. TEST
ENTRE TOUTES LES BORNES ET LA MASSE AVANT DE
TOUCHER.
WARNING: Shock Hazard
Disconnect all power sources to the controller
before removing the wiring box cover. Never remove the
cover when voltage exists on the SunSaver-MPPT power
connections.
Battery Reverse Polarity
(No LED indication) Fully protected against reverse
battery connection. No damage to the controller will result.
Correct the miswire to resume normal operation.
Damaged Local Temperature Sensor
(Charging Status LED: R solid) The local ambient
temperature sensor is short-circuited or damaged. Charging
stops to avoid over or under-charging. This is a critical error.
Contact your authorized Morningstar dealer for service.
Damaged Internal Temperature Sensor
(Charging Status LED: R solid) The internal heatsink
temperature sensor is damaged. This is a critical error.
Contact your authorized Morningstar dealer for service.
High Temperature
(Battery Status LEDs: R-Y sequencing) The heatsink
temperature has exceeded safe limits and the load is
disconnected. The load will automatically reconnect when
the heatsink cools to a safe temperature.
Remote Temperature Sensor (RTS)
(Battery Status LEDs: R/Y - G/Y sequencing) A bad RTS
connection or a severed RTS wire has disconnected the
temperature sensor during charging. Charging automatically
resumes when the problem is xed. To resume operation
without an RTS, disconnect all power to the SunSaver
MPPT, and then reconnect.
High Voltage Transients
Solar, battery, and load power connections are protected
against high voltage transients. In lightning prone areas,
