Maintenance
6.1

Introduction

WARNING: The procedures described in this chapter must be performed by an authorised electrician who
has received the appropriate level of training on this UPS system.
The UPS maintenance requirements are minimal as there are no user-serviceable parts contained within the UPS cabinet.
However, we recommend that the UPS and batteries are inspected and calibrated on a 6 monthly basis as part of a
preventative maintenance schedule to maximise the system's performance, working life and reliability.
6.2

User responsibilities

The UPS equipment should be inspected daily to ensure that the environment in which it is operating is kept cool and dust
free, and the operating temperature and humidity is within the equipment's specified operational range (20°C ~ 25°C).
Any active alarm or status indication that suggests that the UPS is not functioning correctly should be dealt with
immediately by referring to the troubleshooting chapter of this manual or contacting the manufacturer's service desk.
Routine maintenance
WARNING: When working inside the UPS cabinet there is a risk of exposure to potentially lethal AC and
DC voltages. All work that requires internal cabinet access must be carried out by trained personnel only.
The commissioning engineer will leave a service record book with the UPS which will be used to log the UPS service
history. To ensure optimum UPS operation we recommend that the system's operating parameters are checked and
logged every six months.
Preventative maintenance inspections form an integral part of all Extended Warranty Agreements (maintenance contracts)
offered by Kohler Uninterruptible Power Ltd. For further details on Extended Warranty Agreements see the warranty
information at the front of this manual.
A preventative maintenance inspection includes the following:
• Site/environment conditions
• Cooling airflow
• Inverter operation and calibration
• Battery status and condition
• Integrity of alarm and monitoring systems
6.3

Battery testing

A battery test can be initiated from the module control panel and takes approximately 3 minutes to complete. The test
procedure can be carried out irrespective of the operating mode ('on inverter' or 'on bypass') and whether or not the load
is connected, should be performed only if there are no existing alarm conditions and the battery is initially fully charged.
WARNING: Batteries contain dangerous substances that will harm if discarded without out due care. Please
ensure that any faulty batteries are discarded in accordance with local and national codes of practice for the
disposal of hazardous waste.
