Chapter 6 - Maintenance

This section contains the procedures necessary to effect general maintenance of the UPS and battery.
Certain procedures entail gaining internal access to the UPS, and should be undertaken only by a com
petent engineer who is familiar with the operation and layout of the equipment and is fully conversant
with the areas of potential hazard. If there are any doubts concerning safety, or the method of carrying
out any procedure then contact an approved service agent for assistance or advice.
Safety The equipment contains live voltages at ALL Swiss unless externally isolated from the mains
supply, bypass supply and batteries.
Precautions
When working on the UPS it is essential that the safety and precautionary notes in this man
ual are read and FULLY UNDERSTOOD before touching any UPS internal component part.
6.1 -

Scheduled Maintenance

The UPS utilises solid state components not subjected to wear, with the only moving part the cooling
fan. Scheduled maintenance requirements, beyond ensuring that the environmental conditions remain
suitably cool and clean, are therefore minimal. However, a well documented periodic program of inspec
tion and preventive maintenance, as suggested below; will ensure optimum equipment performance
and serve to detect minor malfunctions prior to them developing into a major fault.

6.1.1 - Daily Checks

Carry out a daily walk by inspection of the UPS, checking the following points:

6.1.2 - Weekly Checks

Perform the following checks and log the results:
If there are significant differences from the values previously recorded, note the size, type and location
of any additional load connected to the UPS supply since the previous inspection. This type of informa
tion 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
you should contact the Customer Service & Support Department at the address given at the front of this
manual for advice.
