SBS Overload
Phase A
Alarm NO NO NO YES
With the load on Static Bypass, the phase A
output kVA or kW or RMS current has
exceeded 115% of the nominal per-phase
kVA or kW or RMS current rating. The UPS
will show time remaining until a shutdown
will occur, per the Overload vs. time curve.
The alarm will clear when the overload falls
to below 110% of the rating.

Phase B
SBS Overload
Phase B
Alarm NO NO NO YES

output kVA or kW or RMS current has
exceeded 115% of the nominal per-phase
kVA or kW or RMS current rating. The UPS
will show time remaining until a shutdown
will occur, per the Overload vs. time curve.
The alarm will clear when the overload falls
to below 110% of the rating.

Phase C
SBS Overload
Phase C
Alarm NO NO NO YES
With the load on Static Bypass, the phase C
output kVA or kW or RMS current has
exceeded 115% of the nominal per-phase
kVA or kW or RMS current rating. The UPS
will show time remaining until a shutdown
will occur, per the Overload vs. time curve.

Inverter I
Limit
Inverter
Current Limit
Alarm NO NO NO YES
The instantaneous inverter current of any
one phase has exceeded its pulse-by-pulse
current limit value. The UPS will shutdown
when the Current Overload vs. time curve is
exceeded.
Output OF/UF Output OF/UF Alarm NO YES NO YES
Output frequency differs from the nominal
(60Hz) by more than 0.5Hz. No transfer or
shutdown occurs. Contact Liebert Global

Inv Ovld
Phase A
Inverter
Overload
Phase A
Alarm NO YES NO YES
With the load on UPS, Phase x output KVA
or KW or RMS current has exceeded 105%
of the nominal per phase rating. The UPS
will begin sending the time remaining until a
transfer or shutdown will occur, per the
Overload vs. Time Curve. The alarm
condition will clear when the overload
returns to below the nominal rating.
Inv Ovld
Phase B
Inverter
Overload
Phase B
Alarm NO YES NO YES
With the load on UPS, Phase A output kVA
or kW or RMS current has exceeded 105%
of the nominal per phase rating. The UPS
will begin sending the time remaining until a
transfer or shutdown will occur, per the
Overload vs. Time Curve. The alarm
condition will clear when the overload
returns to below the nominal rating.
