LOADnotPROTECTED
TEMP 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.

The temperature of the cooling plates or output transformer is
too high.
The DC inter-circuit voltage is too high, internal failure
The output voltage of the battery charger is too high, internal
failure.
The battery temperature is too high due to a battery failure or
a too high ambient temperature.
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.
One or more of the DC-capacitors needs replacement due to
ageing or failure.
One or more of the DC-capacitors needs replacement due to
ageing or failure.
Due to a failure the output converter's output is not available.
As a result the load may have been transferred to bypass.
The remaining autonomy is zero.
As a result the load may have been transferred to bypass.
