LOADnotPROTECTED
TEMP TOO HIGH The temperature of the cooling plates or output transformer is
too high.
As a result the load may be transferred to bypass.
The operating temperature can rise intolerable as a result of:
• extreme environmental temperature;
• lack of proper ventilation;
• an overload situation;
• fan failure.
If the UPS operates in “on line” mode, it will switch to bypass mode (if allowed, see explanation
in alarm “UPS overloaded” above) until the temperature is normal again.
If however the UPS operates “on battery”, a shutdown will occur and output power is lost.
LOADnotPROTECTED The DC inter-circuit voltage is too high, internal failure
VOLTAGE TOO HIGH
BATTERY CHARGER
VOLTAGE TOO HIGH The output voltage of the battery charger is too high, internal
failure.
BATTERY CHARGER
TEMP TOO HIGH The battery temperature is too high due to a battery failure or
a too high ambient temperature.
BATTERY CHARGER
NO FLOAT After 24 hours of charging time, the battery voltage did not
reach the normal float voltage.
This may be caused by faulty batteries, many battery packs
connected or a charger fault.
CAPACITOR C2
CAPACITY LOW One or more of the DC-capacitors needs replacement due to
ageing or failure.
CAPACITOR C3
CAPACITY LOW One or more of the DC-capacitors needs replacement due to
ageing or failure.
LOADnotPROTECTED
INVERTER OFF Due to a failure the output converter's output is not available.
As a result the load may have been transferred to bypass.
LOADnotPROTECTED
BATTERY DEPLETED The remaining autonomy is zero.
As a result the load may have been transferred to bypass.
