Factory Trained Engineers
All our engineers in the UPS service division undergo a comprehensive in-house training program on the fundamental checks which must be carried out on the UPS system during routine maintenance. In addition, all engineers attend the manufacturer factory for further training on the use of diagnostic software for fault finding, more in-depth training of the UPS in its operation and the control philosophy. Engineers are fully equipped with the required tools and calibrated test equipment, when attending each site.

The scope of works completed during the maintenance will include:

Thorough external & internal system clean
Power and control cable connections checked for tightness.
Levels checked for rectifier output voltage, when operating on boost charge and float charge.
Check the inverter output voltage and back up battery supply is within the system specifications.
