Series 7400 Single Phase 1+N UPS

Chapter 5

Maintenance

5.1 Introduction

This chapter contains the procedures necessary to effect general maintenance of the UPS module and battery. Certain procedures entail gaining internal access to the UPS, and should only be undertaken by a competent engineer who is familiar with the operation and layout of the equipment and understands the areas of potential hazard. If you have any doubts concerning safety or the method carrying out any procedure then contact an approved service agent for assistance or advice. If the locally approved agent is known to you, then you should contact the Customer Services & Support department at the address shown at the front of this manual.

The manufacturer offers customer training, at a nominal fee, if required. Such training can range from a one-day operator course to in-depth training on maintenance and troubleshooting lasting several days, and can be carried out at the manufacturer’s plant or at the customer premises.

5.2 Safety Precautions

When working on the UPS remember that the equipment contains live voltages at ALL TIMES unless it is externally isolated from the mains supply, bypass supply and batteries. It is essential that the safety and precautionary notes contained throughout this manual are read and FULLY UNDERSTOOD before touching any UPS internal component part.

5.3 Scheduled Maintenance

5.3.1 Daily Checks

The UPS utilises solid-state components which are not subject to wear, with the only moving parts being the cooling fans. Scheduled maintenance requirements, beyond ensuring that the environmental conditions remain suitably cool and clean, are therefore minimal. However, a well documented periodic program of inspection and preventive maintenance, as suggested below, will help to ensure optimum equipment performance and may serve to detect certain minor malfunctions prior to them developing into a major fault.

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

1.Carry out a spot check of the operator control panel; ensuring that all mimic LED indications are normal, all metered parameters are normal and no warning or alarm messages are present on the display panel.

2.Check for obvious signs of overheating.

3.Listen for any noticeable change in audible noise.

4.Ensure that the ventilation grills around the UPS are unobstructed.

5.If possible, log the results of the inspection, noting any discrepancies from the norm.
