8 MAINTENANCE
An ISM system, like other electrical equipment, needs periodic preventive maintenance.
A regular maintenance check of your installation guarantees higher reliability of your ISM.
Preventive maintenance work on the ISM can be done only by trained Service Technicians.
We therefore recommend you sign a Maintenance and Service contract with the local Service Centre
organisation.
The ISM follows the same service program and intervals as for UPS systems.
Service check
If this LED lights up during the normal operation, that means that the unit has not been serviced for the
last 20’000 hours by a GE Trained Technician.
We highly recommend that you contact your Service Centre for preventive maintenance work.
ISM room conditions and temperature
The ISM room has to be maintained clean and free from dust.
A high temperature of the ISM room affects the lifetime of several components inside the equipment.
Component with limited lifetime
We recommend the replacement of component such as lithium battery for the backup of data on the
control boards of the units every 50’000 hours.
