Maintenance 

7.1

Introduction

The UPS does not contain any user-serviceable parts, so the maintenance requirements are minimal other than to ensure

the environment in which the UPS is installed is kept cool and dust free. A clean operating environment will help maximise

the useful working life and reliability of both the UPS and its batteries.

7.2

Scheduled maintenance

It is essential that the UPS system and batteries receive regular preventative maintenance to maximise both the useful

working life and system reliability. When the UPS is commissioned, the commissioning engineer will attach a service

record book inside the front of the UPS which will be used to log its full service history.
We recommend that the UPS system is maintained every six months by a Kohler Uninterruptible Power Ltd. trained

engineer or approved service agent, who will complete the following.

7.2.1  Preventative maintenance inspection

Preventative maintenance inspections form an integral part of all Extended Warranty Agreements (maintenance contracts)

offered by Kohler Uninterruptible Power Ltd. Ltd. 
During a preventative maintenance inspection a trained Kohler Uninterruptible Power Ltd. engineer will check and

validate:

• Site environmental conditions
• Integrity of electrical installation
• Cooling airflow
• Load characteristics
• Integrity of alarm and monitoring systems
• Operation of all installed options
• All stored event logs

7.2.2  System calibration

To ensure optimum UPS operation and efficient load protection we recommended that the system’s operating parameters

are checked and recalibrated where necessary.
During a system calibration a trained Kohler Uninterruptible Power Ltd. engineer will check: 

• Rectifier operation and calibration
• Inverter operation and calibration
• Bypass operation
• Battery status and perform a battery test

WARNING: 

All the operations described in this chapter must be performed by trained personnel.

WARNING: 

Preventative  maintenance  inspections  involve  working  inside  the  UPS  which  contains

hazardous AC and DC voltages, and should be performed only by an authorised engineer who has been

trained by 

Kohler Uninterruptible Power Ltd.
