10. MAINTENANCE & SERVICING
10.1 INTRODUCTION
With extremely high reliability (MTBF >125,000 Hours), OSES Stabilisers require an
exceptionally low level of ongoing annual (or biennial) maintenance or servicing.
Front line servicing, maintenance and most remedial work can usually be performed by
universally available skill sets held by most competent qualified electricians.
With our strategically located dedicated teams of technical support specialists and field
service engineers, we are always on-hand to offer email or telephone technical support
and, where deemed appropriate, direct on-site assistance.
10.2 ROUTINE MAINTENANCE PROCEDURES
In order to ensure reliability and optimise the service life of the unit, we recommended
that the Voltage Stabilizer is subject to periodic (annual or biennial) inspections and
maintenance.
WARNING!
The procedures detailed below should only be carried out by duly
qualified personnel.
The Stabiliser can contain potentially dangerous and life threatening
voltages – up to 600 V AC. Use extreme caution when opening the covers
and do not leave the unit unattended with the doors open or covers off.
Before attempting any maintenance it is imperative that the mains supply to the AC
Automatic Voltage Stabiliser is switched off.
