Series 7400 Single Phase 1+N UPS

5.3.2 Weekly Checks

5.3.3 Annual Service

Carry out the following checks from the mimic panel and log the results:

1.Measure and record the battery float charge voltage.

2.Measure and record the battery charge current.

3.Measure and record the UPS output voltage on all three phases.

4.Measure and record the UPS output line currents. If these are significantly different from the values previously logged then, if possible, record the size, type and location of any additional load connected to the UPS supply since the previous inspection. This type of information could prove useful to the troubleshooting engineer should a problem occur.

If any of the above indications differ greatly from the previously logged values for no apparent reason then you should contact the Customer Service & Support Department at the address given at the front of this manual for advice.

The equipment should be thoroughly cleaned and the following checks carried out annually. This entails working inside the equipment in regions containing hazardous voltages.

Amanufacturer-trained engineer is fully aware of the hazards concerned and will carry out this procedure with the load connected to the maintenance bypass supply; however if the customer decides to carry out this service procedure himself it is imperative that the UPS be totally shut down and isolated from the input mains supply and bypass supplies and batteries using the procedure given below. We therefore strongly recommend that the annual service is carried out by trained personnel.

1.Carry out the weekly checks detailed above.

2.Shut down the UPS following the recommended operating procedure.

3.Isolate the UPS input mains supply externally (also the bypass supply if a split bypass is in use) and isolate the battery.

4.Ensure that the UPS is totally powered down by checking for voltage at the mains input terminals, battery connection terminals, and output terminals (and bypass mains input terminals in a split bypass configuration).

5.Gain full access to the UPS interior by opening its internal hinged safety panel.
