1. Ac input failure.
2. Ac input voltage is high.
3. Ac input voltage is low.
4. Actual responding modules
less than defined.
5. Adapter (PC710) not
responding.
6. All UPS modules not
responding.
7. Auxiliary #N fault.
8. Batteries failed last test.
9. Battery test in progress.

E There is no ac input voltage. The UPS will automatically go to bypass mode, or if the bypass voltage is also absent, then battery mode.
R Verify that the input circuit breakers are ON.
Verify that the input cable connections are secure.
E The ac input voltage is higher than normal.
R The UPS can accommodate a high input voltage for a short period of time, after which it transfers the load to bypass. If the bypass voltage
is also too high, the UPS will go to battery mode.
E The input voltage is lower than normal.
R The UPS automatically transfers the load to bypass. If the bypass voltage is also too low, the UPS will go to battery mode.
E The number of power modules installed is greater than the number of power modules defined to the UPS.
R Either too many modules were defined to the system, or too few modules were inserted into the system.
If too many modules were defined, correct the definition ("Setup > System > Number of modules").
•
If too few modules were inserted, insert the proper number of modules.
•
E PC710 is a communication adapter in the computer rack.
R Replace PC710.
E A communication problem exists between the modules and the controller.
R
• There may be a break in the communication cable, or it has become disconnected.
• The controller may need to be rebooted.
• A single defective module may be monopolizing the communication channel. Pull out one module and see if the problem is solved. If
not, put the module back in, and pull out the next module. Do this with each module. If you find that removing a specific module
resolved the problem, that module is defective and should be replaced with a good module.
E Input dry contact #"N" has changed state.
R The response to this notification depends upon the nature of the external circuit connected to this input dry contact. This is user-defined.
E The last battery test found the battery voltage lower than acceptable.
R
Check value of voltage threshold for battery test. 350 V is recommended. Repeat the test after 2 hrs.
•
Check dc voltage between leads of each battery. If any battery measures <10 V replace it immediately.
•
E A battery test is in progress.
