5.5 FINAL STEPS
•
Disconnect any test equipment that has been connected to the
system and make sure that materials that do not belong in the
equipment have been removed.
• Restore the equipment to its original condition. Make sure the
cabinet is placed so that cooling air has free access.
•
If a failure remains in the equipment, contact the responsible field
engineer.
6 MAINTENANCE
All the components of the inverter system have been developed for
continuous operation and are practically maintenance-free. To ensure
continuous operation, it is recommended that flow of cooling air is
periodically checked and any dust is removed from the units.
Warning!
Do not use pressurized air to remove the dust since the
dust particles can be blown into the interior of the unit and
may cause malfunctions.
If servicing is required (exchange of units, work on the mains supply or
the DC supply etc.) the proper position of the manual maintenance by-
pass switch must be verified.
6.1 USE OF THE MANUAL BY-PASS SWITCH
The manual maintenance by-pass switch is only required for servicing.
This manual switch when operated by-passes the SBS unit and connects
without interruption the mains (“Load on By-pass Input”) or the inverter
outputs (“Load on Inverter Output ") directly to the connected load
equipment depending on the switch position.
Warning!
The manual maintenance by-pass switch may only be
operated by qualified personnel.
