additional power modules.

Option 2: Replace failed modules.

Refer to Module Replacement Section

for procedures.

Runtime is below alarm

threshold

Actual power module redundancy has

fallen below user-speciﬁed

redundancy alarm threshold. Either

power module(s) failed or the load

increased.

Option 1: If possible, install

additional power modules.

Option 2: Replace failed modules.

Refer to Module Replacement Section

for procedures.

Option 3: Decrease load or

reconﬁgure threshold.

Runtime is below alarm

threshold

The predicted runtime is lower than

the user-speciﬁed minimum runtime

alarm threshold. Either the battery

capacity has decreased, or the load

has increased

Option 1: Allow the battery modules

to recharge.

Option 2: If possible, increase the

number of battery modules.

Option 3: Reduce load or re-

conﬁgure threshold.

Load is above kW alarm
